Changelog

+
+
v1.82 (2019-12-07)
+
+- Removed a deprecation notice under PHP 7.4.
+
+
v1.81 (2015-12-20)
+
+- Added GetPageWidth() and GetPageHeight().
+- Fixed a bug in SetXY().
+
+
v1.8 (2015-11-29)
+
+- PHP 5.1.0 or higher is now required.
+- The MakeFont utility now subsets fonts, which can greatly reduce font sizes.
+- Added ToUnicode CMaps to improve text extraction.
+- Added a parameter to AddPage() to rotate the page.
+- Added a parameter to SetY() to indicate whether the x position should be reset or not.
+- Added a parameter to Output() to specify the encoding of the name, and special characters are now properly encoded. Additionally the order of the first two parameters was reversed to be more logical (however the old order is still supported for compatibility).
+- The Error() method now throws an exception.
+- Adding contents before the first AddPage() or after Close() now raises an error.
+- Outputting text with no font selected now raises an error.
+
+
v1.7 (2011-06-18)
+
+- The MakeFont utility has been completely rewritten and doesn't depend on ttf2pt1 anymore.
+- Alpha channel is now supported for PNGs.
+- When inserting an image, it's now possible to specify its resolution.
+- Default resolution for images was increased from 72 to 96 dpi.
+- When inserting a GIF image, no temporary file is used anymore if the PHP version is 5.1 or higher.
+- When output buffering is enabled and the PDF is about to be sent, the buffer is now cleared if it contains only a UTF-8 BOM and/or whitespace (instead of throwing an error).
+- Symbol and ZapfDingbats fonts now support underline style.
+- Custom page sizes are now checked to ensure that width is smaller than height.
+- Standard font files were changed to use the same format as user fonts.
+- A bug in the embedding of Type1 fonts was fixed.
+- A bug related to SetDisplayMode() and the current locale was fixed.
+- A display issue occurring with the Adobe Reader X plug-in was fixed.
+- An issue related to transparency with some versions of Adobe Reader was fixed.
+- The Content-Length header was removed because it caused an issue when the HTTP server applies compression.
+
+
v1.6 (2008-08-03)
+
+- PHP 4.3.10 or higher is now required.
+- GIF image support.
+- Images can now trigger page breaks.
+- Possibility to have different page formats in a single document.
+- Document properties (author, creator, keywords, subject and title) can now be specified in UTF-8.
+- Fixed a bug: when a PNG was inserted through a URL, an error sometimes occurred.
+- An automatic page break in Header() doesn't cause an infinite loop any more.
+- Removed some warning messages appearing with recent PHP versions.
+- Added HTTP headers to reduce problems with IE.
+
+
v1.53 (2004-12-31)
+
+- When the font subdirectory is in the same directory as fpdf.php, it's no longer necessary to define the FPDF_FONTPATH constant.
+- The array $HTTP_SERVER_VARS is no longer used. It could cause trouble on PHP5-based configurations with the register_long_arrays option disabled.
+- Fixed a problem related to Type1 font embedding which caused trouble to some PDF processors.
+- The file name sent to the browser could not contain a space character.
+- The Cell() method could not print the number 0 (you had to pass the string '0').
+
+
v1.52 (2003-12-30)
+
+- Image() now displays the image at 72 dpi if no dimension is given.
+- Output() takes a string as second parameter to indicate destination.
+- Open() is now called automatically by AddPage().
+- Inserting remote JPEG images doesn't generate an error any longer.
+- Decimal separator is forced to dot in the constructor.
+- Added several encodings (Turkish, Thai, Hebrew, Ukrainian and Vietnamese).
+- The last line of a right-aligned MultiCell() was not correctly aligned if it was terminated by a carriage return.
+- No more error message about already sent headers when outputting the PDF to the standard output from the command line.
+- The underlining was going too far for text containing characters \, ( or ).
+- $HTTP_ENV_VARS has been replaced by $HTTP_SERVER_VARS.
+
+
v1.51 (2002-08-03)
+
+- Type1 font support.
+- Added Baltic encoding.
+- The class now works internally in points with the origin at the bottom in order to avoid two bugs occurring with Acrobat 5:
  * The line thickness was too large when printed under Windows 98 SE and ME.
  * TrueType fonts didn't appear immediately inside the plug-in (a substitution font was used), one had to cause a window refresh to make them show up.
+- It's no longer necessary to set the decimal separator as dot to produce valid documents.
+- The clickable area in a cell was always on the left independently from the text alignment.
+- JPEG images in CMYK mode appeared in inverted colors.
+- Transparent PNG images in grayscale or true color mode were incorrectly handled.
+- Adding new fonts now works correctly even with the magic_quotes_runtime option set to on.
+
+
v1.5 (2002-05-28)
+
+- TrueType font (AddFont()) and encoding support (Western and Eastern Europe, Cyrillic and Greek).
+- Added Write() method.
+- Added underlined style.
+- Internal and external link support (AddLink(), SetLink(), Link()).
+- Added right margin management and methods SetRightMargin(), SetTopMargin().
+- Modification of SetDisplayMode() to select page layout.
+- The border parameter of MultiCell() now lets choose borders to draw as Cell().
+- When a document contains no page, Close() now calls AddPage() instead of causing a fatal error.
+
+
v1.41 (2002-03-13)
+
+- Fixed SetDisplayMode() which no longer worked (the PDF viewer used its default display).
+
+
v1.4 (2002-03-02)
+
+- PHP3 is no longer supported.
+- Page compression (SetCompression()).
+- Choice of page format and possibility to change orientation inside document.
+- Added AcceptPageBreak() method.
+- Ability to print the total number of pages (AliasNbPages()).
+- Choice of cell borders to draw.
+- New mode for Cell(): the current position can now move under the cell.
+- Ability to include an image by specifying height only (width is calculated automatically).
+- Fixed a bug: when a justified line triggered a page break, the footer inherited the corresponding word spacing.
+
+
v1.31 (2002-01-12)
+
+- Fixed a bug in drawing frame with MultiCell(): the last line always started from the left margin.
+- Removed Expires HTTP header (gives trouble in some situations).
+- Added Content-disposition HTTP header (seems to help in some situations).
+
+
v1.3 (2001-12-03)
+
+- Line break and text justification support (MultiCell()).
+- Color support (SetDrawColor(), SetFillColor(), SetTextColor()). Possibility to draw filled rectangles and paint cell background.
+- A cell whose width is declared null extends up to the right margin of the page.
+- Line width is now retained from page to page and defaults to 0.2 mm.
+- Added SetXY() method.
+- Fixed a passing by reference done in a deprecated manner for PHP4.
+
+
v1.2 (2001-11-11)
+
+- Added font metric files and GetStringWidth() method.
+- Centering and right-aligning text in cells.
+- Display mode control (SetDisplayMode()).
+- Added methods to set document properties (SetAuthor(), SetCreator(), SetKeywords(), SetSubject(), SetTitle()).
+- Possibility to force PDF download by browser.
+- Added SetX() and GetX() methods.
+- During automatic page break, current abscissa is now retained.
+
+
v1.11 (2001-10-20)
+
+- PNG support doesn't require PHP4/zlib any more. Data are now put directly into PDF without any decompression/recompression stage.
+- Image insertion now works correctly even with magic_quotes_runtime option set to on.
+
+
v1.1 (2001-10-07)
+
+- JPEG and PNG image support.
+
+
v1.01 (2001-10-03)
+
+- Fixed a bug involving page break: in case when Header() doesn't specify a font, the one from previous page was not restored and produced an incorrect document.
+
+
v1.0 (2001-09-17)
+
+- First version.

__construct

+__construct([string orientation [, string unit [, mixed size]]]) +

Description

+This is the class constructor. It allows to set up the page size, the orientation and the +unit of measure used in all methods (except for font sizes). +

Parameters

+
+
orientation
+
+Default page orientation. Possible values are (case insensitive): +
    +
  • P or Portrait
    • +
  • L or Landscape
    • +
+Default value is P. +
+
unit
+
+User unit. Possible values are: +
    +
  • pt: point
    • +
  • mm: millimeter
    • +
  • cm: centimeter
    • +
  • in: inch
    • +
+A point equals 1/72 of inch, that is to say about 0.35 mm (an inch being 2.54 cm). This +is a very common unit in typography; font sizes are expressed in that unit. +
+
+Default value is mm. +
+
size
+
+The size used for pages. It can be either one of the following values (case insensitive): +
    +
  • A3
    • +
  • A4
    • +
  • A5
    • +
  • Letter
    • +
  • Legal
    • +
+or an array containing the width and the height (expressed in the unit given by unit).
+
+Default value is A4. +
+
+

Example

+Example with a custom 100x150 mm page size: +
+
$pdf = new FPDF('P','mm',array(100,150));

AcceptPageBreak

+boolean AcceptPageBreak() +

Description

+Whenever a page break condition is met, the method is called, and the break is issued or not +depending on the returned value. The default implementation returns a value according to the +mode selected by SetAutoPageBreak(). +
+This method is called automatically and should not be called directly by the application. +

Example

+The method is overriden in an inherited class in order to obtain a 3 column layout: +
+
class PDF extends FPDF
+{
+var $col = 0;
+
+function SetCol($col)
+{
+    // Move position to a column
+    $this->col = $col;
+    $x = 10+$col*65;
+    $this->SetLeftMargin($x);
+    $this->SetX($x);
+}
+
+function AcceptPageBreak()
+{
+    if($this->col<2)
+    {
+        // Go to next column
+        $this->SetCol($this->col+1);
+        $this->SetY(10);
+        return false;
+    }
+    else
+    {
+        // Go back to first column and issue page break
+        $this->SetCol(0);
+        return true;
+    }
+}
+}
+
+$pdf = new PDF();
+$pdf->AddPage();
+$pdf->SetFont('Arial','',12);
+for($i=1;$i<=300;$i++)
+    $pdf->Cell(0,5,"Line $i",0,1);
+$pdf->Output();

AddFont

+AddFont(string family [, string style [, string file]]) +

Description

+Imports a TrueType, OpenType or Type1 font and makes it available. It is necessary to generate a font +definition file first with the MakeFont utility. +
+The definition file (and the font file itself when embedding) must be present in the font directory. +If it is not found, the error "Could not include font definition file" is raised. +

Parameters

+
+
family
+
+Font family. The name can be chosen arbitrarily. If it is a standard family name, it will +override the corresponding font. +
+
style
+
+Font style. Possible values are (case insensitive): +
    +
  • empty string: regular
    • +
  • B: bold
    • +
  • I: italic
    • +
  • BI or IB: bold italic
    • +
+The default value is regular. +
+
file
+
+The font definition file. +
+By default, the name is built from the family and style, in lower case with no space. +
+
+

Example

+
+
$pdf->AddFont('Comic','I');
+
+is equivalent to: +
+
$pdf->AddFont('Comic','I','comici.php');

AddLink

+int AddLink() +

Description

+Creates a new internal link and returns its identifier. An internal link is a clickable area +which directs to another place within the document. +

AddPage

+AddPage([string orientation [, mixed size [, int rotation]]]) +

Description

+Adds a new page to the document. If a page is already present, the Footer() method is called +first to output the footer. Then the page is added, the current position set to the top-left +corner according to the left and top margins, and Header() is called to display the header. +
+The font which was set before calling is automatically restored. There is no need to call +SetFont() again if you want to continue with the same font. The same is true for colors and +line width. +
+The origin of the coordinate system is at the top-left corner and increasing ordinates go +downwards. +

Parameters

+
+
orientation
+
+Page orientation. Possible values are (case insensitive): +
    +
  • P or Portrait
    • +
  • L or Landscape
    • +
+The default value is the one passed to the constructor. +

    • +
  • Letter
    • +
  • Legal
    • +
+or an array containing the width and the height (expressed in user unit).
+
+The default value is the one passed to the constructor. +
+
rotation
+
+Angle by which to rotate the page. It must be a multiple of 90; positive values +mean clockwise rotation. The default value is 0. +

    • +
  • If the value is not specified or equal to zero, it is automatically calculated
    • +
+
+
h
+
+Height of the image in the page. There are three cases: +

SetFont

+SetFont(string family [, string style [, float size]]) +

Description

+Sets the font used to print character strings. It is mandatory to call this method +at least once before printing text or the resulting document would not be valid. +
+The font can be either a standard one or a font added via the AddFont() method. Standard fonts +use the Windows encoding cp1252 (Western Europe). +
+The method can be called before the first page is created and the font is kept from page +to page. +
+If you just wish to change the current font size, it is simpler to call SetFontSize(). +
+
+Note: the font definition files must be accessible. They are searched successively in: + +Example using FPDF_FONTPATH: +
+
define('FPDF_FONTPATH','/home/www/font');
+require('fpdf.php');
+
+If the file corresponding to the requested font is not found, the error "Could not include font +definition file" is raised. +

Parameters

+
+
family
+
+Family font. It can be either a name defined by AddFont() or one of the standard families (case +insensitive): +
    +
  • Courier (fixed-width)
    • +
  • Helvetica or Arial (synonymous; sans serif)
    • +
  • Times (serif)
    • +
  • Symbol (symbolic)
    • +
  • ZapfDingbats (symbolic)
    • +
+It is also possible to pass an empty string. In that case, the current family is kept. +
+
style
+
+Font style. Possible values are (case insensitive): +
    +
  • empty string: regular
    • +
  • B: bold
    • +
  • I: italic
    • +
  • U: underline
    • +
+or any combination. The default value is regular. +Bold and italic styles do not apply to Symbol and ZapfDingbats. +
+
size
+
+Font size in points. +
+The default value is the current size. If no size has been specified since the beginning of +the document, the value taken is 12. +
+
+

Example

+
+
// Times regular 12
+$pdf->SetFont('Times');
+// Arial bold 14
+$pdf->SetFont('Arial','B',14);
+// Removes bold
+$pdf->SetFont('');
+// Times bold, italic and underlined 14
+$pdf->SetFont('Times','BIU');

Description

+This method prints text from the current position. When the right margin is reached (or the \n +character is met) a line break occurs and text continues from the left margin. Upon method exit, +the current position is left just at the end of the text. +
+It is possible to put a link on the text. +

Parameters

+
+
h
+
+Line height. +
+
txt
+
+String to print. +
+
link
+
+URL or identifier returned by AddLink(). +
+
+

Example

+
+
// Begin with regular font
+$pdf->SetFont('Arial','',14);
+$pdf->Write(5,'Visit ');
+// Then put a blue underlined link
+$pdf->SetTextColor(0,0,255);
+$pdf->SetFont('','U');
+$pdf->Write(5,'www.fpdf.org','http://www.fpdf.org');

Without getting into those rumors that upset civilians in the seaports and deranged the public mind even far inland, it must be said that professional seamen were especially alarmed. Traders, shipowners, captains of vessels, skippers, and master mariners from Europe and America, naval officers from every country, and at their heels the various national governments on these two continents, were all extremely disturbed by the business. +In essence, over a period of time several ships had encountered "an enormous thing" at sea, a long spindle-shaped object, sometimes giving off a phosphorescent glow, infinitely bigger and faster than any whale. +The relevant data on this apparition, as recorded in various logbooks, agreed pretty closely as to the structure of the object or creature in question, its unprecedented speed of movement, its startling locomotive power, and the unique vitality with which it seemed to be gifted. If it was a cetacean, it exceeded in bulk any whale previously classified by science. No naturalist, neither Cuvier nor Lacépède, neither Professor Dumeril nor Professor de Quatrefages, would have accepted the existence of such a monster sight unseen -- specifically, unseen by their own scientific eyes. +Striking an average of observations taken at different times -- rejecting those timid estimates that gave the object a length of 200 feet, and ignoring those exaggerated views that saw it as a mile wide and three long--you could still assert that this phenomenal creature greatly exceeded the dimensions of anything then known to ichthyologists, if it existed at all. +Now then, it did exist, this was an undeniable fact; and since the human mind dotes on objects of wonder, you can understand the worldwide excitement caused by this unearthly apparition. As for relegating it to the realm of fiction, that charge had to be dropped. +In essence, on July 20, 1866, the steamer Governor Higginson, from the Calcutta & Burnach Steam Navigation Co., encountered this moving mass five miles off the eastern shores of Australia. Captain Baker at first thought he was in the presence of an unknown reef; he was even about to fix its exact position when two waterspouts shot out of this inexplicable object and sprang hissing into the air some 150 feet. So, unless this reef was subject to the intermittent eruptions of a geyser, the Governor Higginson had fair and honest dealings with some aquatic mammal, until then unknown, that could spurt from its blowholes waterspouts mixed with air and steam. +Similar events were likewise observed in Pacific seas, on July 23 of the same year, by the Christopher Columbus from the West India & Pacific Steam Navigation Co. Consequently, this extraordinary cetacean could transfer itself from one locality to another with startling swiftness, since within an interval of just three days, the Governor Higginson and the Christopher Columbus had observed it at two positions on the charts separated by a distance of more than 700 nautical leagues. +Fifteen days later and 2,000 leagues farther, the Helvetia from the Compagnie Nationale and the Shannon from the Royal Mail line, running on opposite tacks in that part of the Atlantic lying between the United States and Europe, respectively signaled each other that the monster had been sighted in latitude 42 degrees 15' north and longitude 60 degrees 35' west of the meridian of Greenwich. From their simultaneous observations, they were able to estimate the mammal's minimum length at more than 350 English feet; this was because both the Shannon and the Helvetia were of smaller dimensions, although each measured 100 meters stem to stern. Now then, the biggest whales, those rorqual whales that frequent the waterways of the Aleutian Islands, have never exceeded a length of 56 meters--if they reach even that. +One after another, reports arrived that would profoundly affect public opinion: new observations taken by the transatlantic liner Pereire, the Inman line's Etna running afoul of the monster, an official report drawn up by officers on the French frigate Normandy, dead-earnest reckonings obtained by the general staff of Commodore Fitz-James aboard the Lord Clyde. In lighthearted countries, people joked about this phenomenon, but such serious, practical countries as England, America, and Germany were deeply concerned. +In every big city the monster was the latest rage; they sang about it in the coffee houses, they ridiculed it in the newspapers, they dramatized it in the theaters. The tabloids found it a fine opportunity for hatching all sorts of hoaxes. In those newspapers short of copy, you saw the reappearance of every gigantic imaginary creature, from "Moby Dick," that dreadful white whale from the High Arctic regions, to the stupendous kraken whose tentacles could entwine a 500-ton craft and drag it into the ocean depths. They even reprinted reports from ancient times: the views of Aristotle and Pliny accepting the existence of such monsters, then the Norwegian stories of Bishop Pontoppidan, the narratives of Paul Egede, and finally the reports of Captain Harrington -- whose good faith is above suspicion--in which he claims he saw, while aboard the Castilian in 1857, one of those enormous serpents that, until then, had frequented only the seas of France's old extremist newspaper, The Constitutionalist. diff --git a/application/third_party/fpdf/tutorial/20k_c2.txt b/application/third_party/fpdf/tutorial/20k_c2.txt new file mode 100644 index 0000000..7b5c565 --- /dev/null +++ b/application/third_party/fpdf/tutorial/20k_c2.txt @@ -0,0 +1,23 @@ +During the period in which these developments were occurring, I had returned from a scientific undertaking organized to explore the Nebraska badlands in the United States. In my capacity as Assistant Professor at the Paris Museum of Natural History, I had been attached to this expedition by the French government. After spending six months in Nebraska, I arrived in New York laden with valuable collections near the end of March. My departure for France was set for early May. In the meantime, then, I was busy classifying my mineralogical, botanical, and zoological treasures when that incident took place with the Scotia. +I was perfectly abreast of this question, which was the big news of the day, and how could I not have been? I had read and reread every American and European newspaper without being any farther along. This mystery puzzled me. Finding it impossible to form any views, I drifted from one extreme to the other. Something was out there, that much was certain, and any doubting Thomas was invited to place his finger on the Scotia's wound. +When I arrived in New York, the question was at the boiling point. The hypothesis of a drifting islet or an elusive reef, put forward by people not quite in their right minds, was completely eliminated. And indeed, unless this reef had an engine in its belly, how could it move about with such prodigious speed? +Also discredited was the idea of a floating hull or some other enormous wreckage, and again because of this speed of movement. +So only two possible solutions to the question were left, creating two very distinct groups of supporters: on one side, those favoring a monster of colossal strength; on the other, those favoring an "underwater boat" of tremendous motor power. +Now then, although the latter hypothesis was completely admissible, it couldn't stand up to inquiries conducted in both the New World and the Old. That a private individual had such a mechanism at his disposal was less than probable. Where and when had he built it, and how could he have built it in secret? +Only some government could own such an engine of destruction, and in these disaster-filled times, when men tax their ingenuity to build increasingly powerful aggressive weapons, it was possible that, unknown to the rest of the world, some nation could have been testing such a fearsome machine. The Chassepot rifle led to the torpedo, and the torpedo has led to this underwater battering ram, which in turn will lead to the world putting its foot down. At least I hope it will. +But this hypothesis of a war machine collapsed in the face of formal denials from the various governments. Since the public interest was at stake and transoceanic travel was suffering, the sincerity of these governments could not be doubted. Besides, how could the assembly of this underwater boat have escaped public notice? Keeping a secret under such circumstances would be difficult enough for an individual, and certainly impossible for a nation whose every move is under constant surveillance by rival powers. +So, after inquiries conducted in England, France, Russia, Prussia, Spain, Italy, America, and even Turkey, the hypothesis of an underwater Monitor was ultimately rejected. +After I arrived in New York, several people did me the honor of consulting me on the phenomenon in question. In France I had published a two-volume work, in quarto, entitled The Mysteries of the Great Ocean Depths. Well received in scholarly circles, this book had established me as a specialist in this pretty obscure field of natural history. My views were in demand. As long as I could deny the reality of the business, I confined myself to a flat "no comment." But soon, pinned to the wall, I had to explain myself straight out. And in this vein, "the honorable Pierre Aronnax, Professor at the Paris Museum," was summoned by The New York Herald to formulate his views no matter what. +I complied. Since I could no longer hold my tongue, I let it wag. I discussed the question in its every aspect, both political and scientific, and this is an excerpt from the well-padded article I published in the issue of April 30. + +"Therefore," I wrote, "after examining these different hypotheses one by one, we are forced, every other supposition having been refuted, to accept the existence of an extremely powerful marine animal. +"The deepest parts of the ocean are totally unknown to us. No soundings have been able to reach them. What goes on in those distant depths? What creatures inhabit, or could inhabit, those regions twelve or fifteen miles beneath the surface of the water? What is the constitution of these animals? It's almost beyond conjecture. +"However, the solution to this problem submitted to me can take the form of a choice between two alternatives. +"Either we know every variety of creature populating our planet, or we do not. +"If we do not know every one of them, if nature still keeps ichthyological secrets from us, nothing is more admissible than to accept the existence of fish or cetaceans of new species or even new genera, animals with a basically 'cast-iron' constitution that inhabit strata beyond the reach of our soundings, and which some development or other, an urge or a whim if you prefer, can bring to the upper level of the ocean for long intervals. +"If, on the other hand, we do know every living species, we must look for the animal in question among those marine creatures already cataloged, and in this event I would be inclined to accept the existence of a giant narwhale. +"The common narwhale, or sea unicorn, often reaches a length of sixty feet. Increase its dimensions fivefold or even tenfold, then give this cetacean a strength in proportion to its size while enlarging its offensive weapons, and you have the animal we're looking for. It would have the proportions determined by the officers of the Shannon, the instrument needed to perforate the Scotia, and the power to pierce a steamer's hull. +"In essence, the narwhale is armed with a sort of ivory sword, or lance, as certain naturalists have expressed it. It's a king-sized tooth as hard as steel. Some of these teeth have been found buried in the bodies of baleen whales, which the narwhale attacks with invariable success. Others have been wrenched, not without difficulty, from the undersides of vessels that narwhales have pierced clean through, as a gimlet pierces a wine barrel. The museum at the Faculty of Medicine in Paris owns one of these tusks with a length of 2.25 meters and a width at its base of forty-eight centimeters! +"All right then! Imagine this weapon to be ten times stronger and the animal ten times more powerful, launch it at a speed of twenty miles per hour, multiply its mass times its velocity, and you get just the collision we need to cause the specified catastrophe. +"So, until information becomes more abundant, I plump for a sea unicorn of colossal dimensions, no longer armed with a mere lance but with an actual spur, like ironclad frigates or those warships called 'rams,' whose mass and motor power it would possess simultaneously. +"This inexplicable phenomenon is thus explained away--unless it's something else entirely, which, despite everything that has been sighted, studied, explored and experienced, is still possible!" diff --git a/application/third_party/fpdf/tutorial/calligra.php

Minimal example

+Let's start with the classic example: +
+
<?php
+require('fpdf.php');
+
+$pdf = new FPDF();
+$pdf->AddPage();
+$pdf->SetFont('Arial','B',16);
+$pdf->Cell(40,10,'Hello World!');
+$pdf->Output();
+?>
+
+

[Demo]

+After including the library file, we create an FPDF object. +The constructor is used here with the default values: pages are in A4 portrait and +the unit of measure is millimeter. It could have been specified explicitly with: +
+
$pdf = new FPDF('P','mm','A4');
+
+
+It's possible to use landscape (L), other page sizes (such as Letter and +Legal) and units (pt, cm, in). +
+
+There's no page at the moment, so we have to add one with AddPage(). The origin +is at the upper-left corner and the current position is by default set at 1 cm from the +borders; the margins can be changed with SetMargins(). +
+
+Before we can print text, it's mandatory to select a font with SetFont(). +We choose Arial bold 16: +
+
$pdf->SetFont('Arial','B',16);
+
+
+We could have specified italics with I, underlined with U or a regular font with an empty string +(or any combination). Note that the font size is given in points, not millimeters (or another user +unit); it's the only exception. The other standard fonts are Times, Courier, Symbol and ZapfDingbats. +
+
+We can now print a cell with Cell(). A cell is a rectangular area, possibly framed, +which contains a line of text. It is output at the current position. We specify its dimensions, +its text (centered or aligned), if borders should be drawn, and where the current position +moves after it (to the right, below or to the beginning of the next line). To add a frame, we would do this: +
+
$pdf->Cell(40,10,'Hello World !',1);
+
+
+To add a new cell next to it with centered text and go to the next line, we would do: +
+
$pdf->Cell(60,10,'Powered by FPDF.',0,1,'C');
+
+
+Remark: the line break can also be done with Ln(). This method additionnaly allows to specify +the height of the break. +
+
+Finally, the document is closed and sent to the browser with Output(). We could have saved +it to a file by passing the appropriate parameters. +
+
+Caution: in case when the PDF is sent to the browser, nothing else must be output by the +script, neither before nor after (no HTML, not even a space or a carriage return). If you send something +before, you will get the error message: "Some data has already been output, can't send PDF file". If you +send something after, the document might not display. + + diff --git a/application/third_party/fpdf/tutorial/tuto1.php b/application/third_party/fpdf/tutorial/tuto1.php new file mode 100644 index 0000000..3ab55a1 --- /dev/null +++ b/application/third_party/fpdf/tutorial/tuto1.php @@ -0,0 +1,9 @@ +AddPage(); +$pdf->SetFont('Arial','B',16); +$pdf->Cell(40,10,'Hello World!'); +$pdf->Output(); +?> diff --git a/application/third_party/fpdf/tutorial/tuto2.htm b/application/third_party/fpdf/tutorial/tuto2.htm new file mode 100644 index 0000000..c402cf4 --- /dev/null +++ b/application/third_party/fpdf/tutorial/tuto2.htm @@ -0,0 +1,80 @@ + + + + +Header, footer, page break and image + + + +

Header, footer, page break and image

+
+class PDF extends FPDF
+{
+// Page header
+function Header()
+{

+
+

[Demo]

+This example makes use of the Header() and Footer() methods to process page headers and +footers. They are called automatically. They already exist in the FPDF class but do nothing, +therefore we have to extend the class and override them. +
+
+The logo is printed with the Image() method by specifying its upper-left corner and +its width. The height is calculated automatically to respect the image proportions. +
+
+To print the page number, a null value is passed as the cell width. It means that the cell +should extend up to the right margin of the page; this is handy to center text. The current page +number is returned by the PageNo() method; as for the total number of pages, it's obtained +via the special value {nb} which is substituted when the document is finished +(provided you first called AliasNbPages()). +
+Note the use of the SetY() method which allows to set position at an absolute location in +the page, starting from the top or the bottom. +
+
+Another interesting feature is used here: the automatic page breaking. As soon as a cell would +cross a limit in the page (at 2 centimeters from the bottom by default), a break is issued +and the font restored. Although the header and footer select their own font (Arial), the body +continues with Times. This mechanism of automatic restoration also applies to colors and line +width. The limit which triggers page breaks can be set with SetAutoPageBreak(). + + diff --git a/application/third_party/fpdf/tutorial/tuto2.php b/application/third_party/fpdf/tutorial/tuto2.php new file mode 100644 index 0000000..6a1b4f8 --- /dev/null +++ b/application/third_party/fpdf/tutorial/tuto2.php @@ -0,0 +1,41 @@ +Image('logo.png',10,6,30); + // Arial bold 15 + $this->SetFont('Arial','B',15); + // Move to the right + $this->Cell(80); + // Title + $this->Cell(30,10,'Title',1,0,'C'); + // Line break + $this->Ln(20); +} + +// Page footer +function Footer() +{ + // Position at 1.5 cm from bottom + $this->SetY(-15); + // Arial italic 8 + $this->SetFont('Arial','I',8); + // Page number + $this->Cell(0,10,'Page '.$this->PageNo().'/{nb}',0,0,'C'); +} +} + +// Instanciation of inherited class +$pdf = new PDF(); +$pdf->AliasNbPages(); +$pdf->AddPage(); +$pdf->SetFont('Times','',12); +for($i=1;$i<=40;$i++) + $pdf->Cell(0,10,'Printing line number '.$i,0,1); +$pdf->Output(); +?> diff --git a/application/third_party/fpdf/tutorial/tuto3.htm b/application/third_party/fpdf/tutorial/tuto3.htm new file mode 100644 index 0000000..5d8363f --- /dev/null +++ b/application/third_party/fpdf/tutorial/tuto3.htm @@ -0,0 +1,115 @@ + + + + +Line breaks and colors + + + +

+The GetStringWidth() method allows to determine the length of a string in the current font, +which is used here to calculate the position and the width of the frame surrounding the title. +Then colors are set (via SetDrawColor(), SetFillColor() and SetTextColor()) and the +thickness of the line is set to 1 mm (instead of 0.2 by default) with SetLineWidth(). Finally, +we output the cell (the last parameter true indicates that the background must +be filled). +
+
+The method used to print the paragraphs is MultiCell(). Each time a line reaches the +right extremity of the cell or a carriage return character is met, a line break is issued +and a new cell automatically created under the current one. Text is justified by default. +
+
+Two document properties are defined: the title (SetTitle()) and the author (SetAuthor()). +There are several ways to view them in Adobe Reader. The first one is to open the file directly with +the reader, go to the File menu and choose the Properties option. The second one, also available from +the plug-in, is to right-click and select Document Properties.

[Demo]

+A table being just a collection of cells, it's natural to build one from them. The first +example is achieved in the most basic way possible: simple framed cells, all of the same size +and left aligned. The result is rudimentary but very quick to obtain. +
+
+The second table brings some improvements: each column has its own width, headings are centered, +and numbers right aligned. Moreover, horizontal lines have been removed. This is done by means +of the border parameter of the Cell() method, which specifies which sides of the +cell must be drawn. Here we want the left (L) and right (R) ones. It remains +the problem of the horizontal line to finish the table. There are two possibilities: either +check for the last line in the loop, in which case we use LRB for the border +parameter; or, as done here, add the line once the loop is over. +

[Demo]

+The new method to print text is Write(). It's very close to MultiCell(); the differences are: +
    +
  • The end of line is at the right margin and the next line begins at the left one
    • +
  • The current position moves at the end of the text
    • +
+So it allows to write a chunk of text, alter the font style, then continue from the exact +place we left it. On the other hand, you cannot justify it. +
+
+The method is used on the first page to put a link pointing to the second one. The beginning of +the sentence is written in regular style, then we switch to underline and finish it. The link +is created with AddLink(), which returns a link identifier. The identifier is +passed as third parameter of Write(). Once the second page is created, we use SetLink() to +make the link point to the beginning of the current page. +
+
+Then we put an image with an external link on it. An external link is just a URL. It's passed as +last parameter of Image(). +
+
+Finally, the left margin is moved after the image with SetLeftMargin() and some text in +HTML format is output. A very simple HTML parser is used for this, based on regular expressions. +Recognized tags are <b>, <i>, <u>, <a> and <br>; the others are +ignored. The parser also makes use of the Write() method. An external link is put the same way as +an internal one (third parameter of Write()). Note that Cell() also allows to put links. + + diff --git a/application/third_party/fpdf/tutorial/tuto6.php b/application/third_party/fpdf/tutorial/tuto6.php new file mode 100644 index 0000000..427e4d3 --- /dev/null +++ b/application/third_party/fpdf/tutorial/tuto6.php @@ -0,0 +1,113 @@ +/U',$html,-1,PREG_SPLIT_DELIM_CAPTURE); + foreach($a as $i=>$e) + { + if($i%2==0) + { + // Text + if($this->HREF) + $this->PutLink($this->HREF,$e); + else + $this->Write(5,$e); + } + else + { + // Tag + if($e[0]=='/') + $this->CloseTag(strtoupper(substr($e,1))); + else + { + // Extract attributes + $a2 = explode(' ',$e); + $tag = strtoupper(array_shift($a2)); + $attr = array(); + foreach($a2 as $v) + { + if(preg_match('/([^=]*)=["\']?([^"\']*)/',$v,$a3)) + $attr[strtoupper($a3[1])] = $a3[2]; + } + $this->OpenTag($tag,$attr); + } + } + } +} + +function OpenTag($tag, $attr) +{ + // Opening tag + if($tag=='B' || $tag=='I' || $tag=='U') + $this->SetStyle($tag,true); + if($tag=='A') + $this->HREF = $attr['HREF']; + if($tag=='BR') + $this->Ln(5); +} + +function CloseTag($tag) +{ + // Closing tag + if($tag=='B' || $tag=='I' || $tag=='U') + $this->SetStyle($tag,false); + if($tag=='A') + $this->HREF = ''; +} + +function SetStyle($tag, $enable) +{ + // Modify style and select corresponding font + $this->$tag += ($enable ? 1 : -1); + $style = ''; + foreach(array('B', 'I', 'U') as $s) + { + if($this->$s>0) + $style .= $s; + } + $this->SetFont('',$style); +} + +function PutLink($URL, $txt) +{ + // Put a hyperlink + $this->SetTextColor(0,0,255); + $this->SetStyle('U',true); + $this->Write(5,$txt,$URL); + $this->SetStyle('U',false); + $this->SetTextColor(0); +} +} + +$html = 'You can now easily print text mixing different styles: bold, italic, +underlined, or all at once!

Adding new fonts and encodings

+This tutorial explains how to use TrueType, OpenType and Type1 fonts so that you are not limited to the +standard fonts anymore. The other benefit is that you can choose the text encoding, which allows you to +use other languages than the Western ones (the standard fonts support only cp1252 aka windows-1252). +
+
+For OpenType, only the format based on TrueType is supported (not the one based on Type1).
+For Type1, you will need the corresponding AFM file (it is usually provided with the font). +
+
+Adding a new font requires two steps: +
    +
  • Generation of the font definition file
    • +
  • Declaration of the font in the script
    • +
+ +

Generation of the font definition file

+The first step consists in generating a PHP file containing all the information needed by FPDF; +in addition, the font file is compressed. To do this, a helper script is provided in the makefont +directory of the package: makefont.php. It contains the following function: +
+
+MakeFont(string fontfile [, string enc [, boolean embed [, boolean subset]]]) +
+
fontfile
+
+

Path to the .ttf, .otf or .pfb file.

+
+
enc
+
+

Name of the encoding to use. Default value: cp1252.

+
+
embed
+
+

Whether to embed the font or not. Default value: true.

+
+
subset
+
+

Whether to subset the font or not. Default value: true.

+
+
+The first parameter is the name of the font file. The extension must be either .ttf, .otf or .pfb and +determines the font type. If your Type1 font is in ASCII format (.pfa), you can convert it to binary +(.pfb) with the help of t1utils. +
+
+For Type1 fonts, the corresponding .afm file must be present in the same directory. +
+
+The encoding defines the association between a code (from 0 to 255) and a character. The first 128 are +always the same and correspond to ASCII; the following are variable. Encodings are stored in .map +files. The available ones are: +
    +
  • cp1250 (Central Europe)
    • +
  • cp1251 (Cyrillic)
    • +
  • cp1252 (Western Europe)
    • +
  • cp1253 (Greek)
    • +
  • cp1254 (Turkish)
    • +
  • cp1255 (Hebrew)
    • +
  • cp1257 (Baltic)
    • +
  • cp1258 (Vietnamese)
    • +
  • cp874 (Thai)
    • +
  • ISO-8859-1 (Western Europe)
    • +
  • ISO-8859-2 (Central Europe)
    • +
  • ISO-8859-4 (Baltic)
    • +
  • ISO-8859-5 (Cyrillic)
    • +
  • ISO-8859-7 (Greek)
    • +
  • ISO-8859-9 (Turkish)
    • +
  • ISO-8859-11 (Thai)
    • +
  • ISO-8859-15 (Western Europe)
    • +
  • ISO-8859-16 (Central Europe)
    • +
  • KOI8-R (Russian)
    • +
  • KOI8-U (Ukrainian)
    • +
+Of course, the font must contain the characters corresponding to the selected encoding. +
+
+The third parameter indicates whether the font should be embedded in the PDF or not. When a font is +not embedded, it is searched in the system. The advantage is that the PDF file is smaller; on the +other hand, if it is not available, then a substitution font is used. So you should ensure that the +needed font is installed on the client systems. Embedding is the recommended option to guarantee a +correct rendering. +
+
+The last parameter indicates whether subsetting should be used, that is to say, whether only +the characters from the selected encoding should be kept in the embedded font. As a result, +the size of the PDF file can be greatly reduced, especially if the original font was big. +
+
+After you have called the function (create a new file for this and include makefont.php), a .php file +is created, with the same name as the font file. You may rename it if you wish. If the case of embedding, +the font file is compressed and gives a second file with .z as extension (except if the compression +function is not available, it requires Zlib). You may rename it too, but in this case you have to change +the variable $file in the .php file accordingly. +
+
+Example: +
+
<?php
+require('makefont/makefont.php');
+
+MakeFont('C:\\Windows\\Fonts\\comic.ttf','cp1252');
+?>
+
+which gives the files comic.php and comic.z. +
+
+Then copy the generated files to the font directory. If the font file could not be compressed, copy +it directly instead of the .z version. +
+
+Another way to call MakeFont() is through the command line: +
+
+php makefont\makefont.php C:\Windows\Fonts\comic.ttf cp1252 +
+
+Finally, for TrueType and OpenType fonts, you can also generate the files +online instead of doing it manually. + +

Declaration of the font in the script

+The second step is simple. You just need to call the AddFont() method: +
+
$pdf->AddFont('Comic','','comic.php');
+
+
+And the font is now available (in regular and underlined styles), usable like the others. If we +had worked with Comic Sans MS Bold (comicbd.ttf), we would have written: +
+
$pdf->AddFont('Comic','B','comicbd.php');
+
+
+ +

Example

+Let's now see a complete example. We will use the font Calligrapher. +The first step is the generation of the font files: +
+
<?php
+require('makefont/makefont.php');
+
+MakeFont('calligra.ttf','cp1252');
+?>
+
+The script gives the following report: +
+
+Warning: character Euro is missing
+Warning: character zcaron is missing
+Font file compressed: calligra.z
+Font definition file generated: calligra.php
+
+The euro character is not present in the font (it's too old). Another character is missing too. +
+
+Alternatively we could have used the command line: +
+
+php makefont\makefont.php calligra.ttf cp1252 +
+
+or used the online generator. +
+
+We can now copy the two generated files to the font directory and write the script: +
+
<?php
+require('fpdf.php');
+
+$pdf = new FPDF();
+$pdf->AddFont('Calligrapher','','calligra.php');
+$pdf->AddPage();
+$pdf->SetFont('Calligrapher','',35);
+$pdf->Write(10,'Enjoy new fonts with FPDF!');
+$pdf->Output();
+?>
+
+

+                   GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. 
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+**********************************************************************
+
+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. 
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    
+    Copyright (C)   
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see .
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+      Copyright (C)   
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+.

+### Third party fonts:
+
+This library may include third party font files released with different licenses.
+
+All the PHP files on the fonts directory are subject to the general TCPDF license (GNU-LGPLv3),
+they do not contain any binary data but just a description of the general properties of a particular font.
+These files can be also generated on the fly using the font utilities and TCPDF methods.
+
+All the original binary TTF font files have been renamed for compatibility with TCPDF and compressed using the gzcompress PHP function that uses the ZLIB data format (.z files).
+
+The binary files (.z) that begins with the prefix "free" have been extracted from the GNU FreeFont collection (GNU-GPLv3).
+The binary files (.z) that begins with the prefix "pdfa" have been derived from the GNU FreeFont, so they are subject to the same license.
+For the details of Copyright, License and other information, please check the files inside the directory fonts/freefont-20120503
+Link : http://www.gnu.org/software/freefont/
+
+The binary files (.z) that begins with the prefix "dejavu" have been extracted from the DejaVu fonts 2.33 (Bitstream) collection.
+For the details of Copyright, License and other information, please check the files inside the directory fonts/dejavu-fonts-ttf-2.33
+Link : http://dejavu-fonts.org
+
+The binary files (.z) that begins with the prefix "ae" have been extracted from the Arabeyes.org collection (GNU-GPLv2).
+Link : http://projects.arabeyes.org/
+
+### ICC profile:
+
+TCPDF includes the sRGB.icc profile from the icc-profiles-free Debian package:
+https://packages.debian.org/source/stable/icc-profiles-free

+	 * @param $fonttype (string) Font type. Leave empty for autodetect mode. Valid values are: TrueTypeUnicode, TrueType, Type1, CID0JP = CID-0 Japanese, CID0KR = CID-0 Korean, CID0CS = CID-0 Chinese Simplified, CID0CT = CID-0 Chinese Traditional.
+	 * @param $enc (string) Name of the encoding table to use. Leave empty for default mode. Omit this parameter for TrueType Unicode and symbolic fonts like Symbol or ZapfDingBats.
+	 * @param $flags (int) Unsigned 32-bit integer containing flags specifying various characteristics of the font (PDF32000:2008 - 9.8.2 Font Descriptor Flags): +1 for fixed font; +4 for symbol or +32 for non-symbol; +64 for italic. Fixed and Italic mode are generally autodetected so you have to set it to 32 = non-symbolic font (default) or 4 = symbolic font.
+	 * @param $outpath (string) Output path for generated font files (must be writeable by the web server). Leave empty for default font folder.
+	 * @param $platid (int) Platform ID for CMAP table to extract (when building a Unicode font for Windows this value should be 3, for Macintosh should be 1).
+	 * @param $encid (int) Encoding ID for CMAP table to extract (when building a Unicode font for Windows this value should be 1, for Macintosh should be 0). When Platform ID is 3, legal values for Encoding ID are: 0=Symbol, 1=Unicode, 2=ShiftJIS, 3=PRC, 4=Big5, 5=Wansung, 6=Johab, 7=Reserved, 8=Reserved, 9=Reserved, 10=UCS-4.
+	 * @param $addcbbox (boolean) If true includes the character bounding box information on the php font file.
+	 * @param $link (boolean) If true link to system font instead of copying the font data (not transportable) - Note: do not work with Type1 fonts.
+	 * @return (string) TCPDF font name or boolean false in case of error.

+	 * This method allows printing text with line breaks.
+	 * They can be automatic (as soon as the text reaches the right border of the cell) or explicit (via the \n character). As many cells as necessary are output, one below the other.
      
+	 * Text can be aligned, centered or justified. The cell block can be framed and the background painted.
+	 * @param $w (float) Width of cells. If 0, they extend up to the right margin of the page.
+	 * @param $h (float) Cell minimum height. The cell extends automatically if needed.
+	 * @param $txt (string) String to print
+	 * @param $border (mixed) Indicates if borders must be drawn around the cell. The value can be a number:
      • 0: no border (default)
      • 1: frame
       or a string containing some or all of the following characters (in any order):
      • L: left
      • T: top
      • R: right
      • B: bottom
       or an array of line styles for each border group - for example: array('LTRB' => array('width' => 2, 'cap' => 'butt', 'join' => 'miter', 'dash' => 0, 'color' => array(0, 0, 0)))
+	 * @param $align (string) Allows to center or align the text. Possible values are:
      • L or empty string: left align
      • C: center
      • R: right align
      • J: justification (default value when $ishtml=false)
      
+	 * @param $fill (boolean) Indicates if the cell background must be painted (true) or transparent (false).
+	 * @param $ln (int) Indicates where the current position should go after the call. Possible values are:
      • 0: to the right
      • 1: to the beginning of the next line [DEFAULT]
      • 2: below
      
+	 * @param $x (float) x position in user units
+	 * @param $y (float) y position in user units
+	 * @param $reseth (boolean) if true reset the last cell height (default true).
+	 * @param $stretch (int) font stretch mode: 
      • 0 = disabled
      • 1 = horizontal scaling only if text is larger than cell width
      • 2 = forced horizontal scaling to fit cell width
      • 3 = character spacing only if text is larger than cell width
      • 4 = forced character spacing to fit cell width
       General font stretching and scaling values will be preserved when possible.
+	 * @param $ishtml (boolean) INTERNAL USE ONLY -- set to true if $txt is HTML content (default = false). Never set this parameter to true, use instead writeHTMLCell() or writeHTML() methods.
+	 * @param $autopadding (boolean) if true, uses internal padding and automatically adjust it to account for line width.
+	 * @param $maxh (float) maximum height. It should be >= $h and less then remaining space to the bottom of the page, or 0 for disable this feature. This feature works only when $ishtml=false.
+	 * @param $valign (string) Vertical alignment of text (requires $maxh = $h > 0). Possible values are:
      • T: TOP
      • M: middle
      • B: bottom
      . This feature works only when $ishtml=false and the cell must fit in a single page.
+	 * @param $fitcell (boolean) if true attempt to fit all the text within the cell by reducing the font size (do not work in HTML mode). $maxh must be greater than 0 and equal to $h.
+	 * @return int Return the number of cells or 1 for html mode.
+	 * @public
+	 * @since 1.3
+	 * @see SetFont(), SetDrawColor(), SetFillColor(), SetTextColor(), SetLineWidth(), Cell(), Write(), SetAutoPageBreak()

+	 * 
      • explicit width and height (expressed in user unit)
        • 
+	 * 
      • one explicit dimension, the other being calculated automatically in order to keep the original proportions
        • 
+	 * 
      • no explicit dimension, in which case the image is put at 72 dpi
      
+	 * Supported formats are JPEG and PNG images whitout GD library and all images supported by GD: GD, GD2, GD2PART, GIF, JPEG, PNG, BMP, XBM, XPM;
+	 * The format can be specified explicitly or inferred from the file extension.
      
+	 * It is possible to put a link on the image.
      
+	 * Remark: if an image is used several times, only one copy will be embedded in the file.
      
+	 * @param $file (string) Name of the file containing the image or a '@' character followed by the image data string. To link an image without embedding it on the document, set an asterisk character before the URL (i.e.: '*http://www.example.com/image.jpg').
+	 * @param $x (float) Abscissa of the upper-left corner (LTR) or upper-right corner (RTL).
+	 * @param $y (float) Ordinate of the upper-left corner (LTR) or upper-right corner (RTL).
+	 * @param $w (float) Width of the image in the page. If not specified or equal to zero, it is automatically calculated.
+	 * @param $h (float) Height of the image in the page. If not specified or equal to zero, it is automatically calculated.
+	 * @param $type (string) Image format. Possible values are (case insensitive): JPEG and PNG (whitout GD library) and all images supported by GD: GD, GD2, GD2PART, GIF, JPEG, PNG, BMP, XBM, XPM;. If not specified, the type is inferred from the file extension.
+	 * @param $link (mixed) URL or identifier returned by AddLink().
+	 * @param $align (string) Indicates the alignment of the pointer next to image insertion relative to image height. The value can be:
      • T: top-right for LTR or top-left for RTL
      • M: middle-right for LTR or middle-left for RTL
      • B: bottom-right for LTR or bottom-left for RTL
      • N: next line
      
+	 * @param $resize (mixed) If true resize (reduce) the image to fit $w and $h (requires GD or ImageMagick library); if false do not resize; if 2 force resize in all cases (upscaling and downscaling).
+	 * @param $dpi (int) dot-per-inch resolution used on resize
+	 * @param $palign (string) Allows to center or align the image on the current line. Possible values are:
      • L : left align
      • C : center
      • R : right align
      • '' : empty string : left for LTR or right for RTL
      
+	 * @param $ismask (boolean) true if this image is a mask, false otherwise
+	 * @param $imgmask (mixed) image object returned by this function or false
+	 * @param $border (mixed) Indicates if borders must be drawn around the cell. The value can be a number:
      • 0: no border (default)
      • 1: frame
       or a string containing some or all of the following characters (in any order):
      • L: left
      • T: top
      • R: right
      • B: bottom
       or an array of line styles for each border group - for example: array('LTRB' => array('width' => 2, 'cap' => 'butt', 'join' => 'miter', 'dash' => 0, 'color' => array(0, 0, 0)))
+	 * @param $fitbox (mixed) If not false scale image dimensions proportionally to fit within the ($w, $h) box. $fitbox can be true or a 2 characters string indicating the image alignment inside the box. The first character indicate the horizontal alignment (L = left, C = center, R = right) the second character indicate the vertical algnment (T = top, M = middle, B = bottom).
+	 * @param $hidden (boolean) If true do not display the image.
+	 * @param $fitonpage (boolean) If true the image is resized to not exceed page dimensions.
+	 * @param $alt (boolean) If true the image will be added as alternative and not directly printed (the ID of the image will be returned).
+	 * @param $altimgs (array) Array of alternate images IDs. Each alternative image must be an array with two values: an integer representing the image ID (the value returned by the Image method) and a boolean value to indicate if the image is the default for printing.
