// Description : This is a PHP class for generating PDF documents without
//               requiring external extensions.
//
// NOTE:
//   This class was originally derived in 2002 from the Public
//   Domain FPDF class by Olivier Plathey (http://www.fpdf.org),
//   but now is almost entirely rewritten and contains thousands of
//   new lines of code and hundreds new features.
//
// Main features:
//  * no external libraries are required for the basic functions;
//  * all standard page formats, custom page formats, custom margins and units of measure;
//  * UTF-8 Unicode and Right-To-Left languages;
//  * TrueTypeUnicode, OpenTypeUnicode, TrueType, OpenType, Type1 and CID-0 fonts;
//  * font subsetting;
//  * methods to publish some XHTML + CSS code, Javascript and Forms;
//  * images, graphic (geometric figures) and transformation methods;
//  * supports JPEG, PNG and SVG images natively, all images supported by GD (GD, GD2, GD2PART, GIF, JPEG, PNG, BMP, XBM, XPM) and all images supported via ImagMagick (http://www.imagemagick.org/www/formats.html)
//  * 1D and 2D barcodes: CODE 39, ANSI MH10.8M-1983, USD-3, 3 of 9, CODE 93, USS-93, Standard 2 of 5, Interleaved 2 of 5, CODE 128 A/B/C, 2 and 5 Digits UPC-Based Extention, EAN 8, EAN 13, UPC-A, UPC-E, MSI, POSTNET, PLANET, RMS4CC (Royal Mail 4-state Customer Code), CBC (Customer Bar Code), KIX (Klant index - Customer index), Intelligent Mail Barcode, Onecode, USPS-B-3200, CODABAR, CODE 11, PHARMACODE, PHARMACODE TWO-TRACKS, QR-Code, PDF417;
//  * Grayscale, RGB, CMYK, Spot Colors and Transparencies;
//  * automatic page header and footer management;
//  * document encryption up to 256 bit and digital signature certifications;
//  * transactions to UNDO commands;
//  * PDF annotations, including links, text and file attachments;
//  * text rendering modes (fill, stroke and clipping);
//  * multiple columns mode;
//  * no-write page regions;
//  * bookmarks and table of content;
//  * text hyphenation;
//  * text stretching and spacing (tracking/kerning);
//  * automatic page break, line break and text alignments including justification;
//  * automatic page numbering and page groups;
//  * move and delete pages;
//  * page compression (requires php-zlib extension);
//  * XOBject Templates;

 /**
	 * This is the class constructor.
	 * It allows to set up the page format, the orientation and the measure unit used in all the methods (except for the font sizes).
	 * @param string $orientation page orientation. Possible values are (case insensitive):<ul><li>P or Portrait (default)</li><li>L or Landscape</li><li>'' (empty string) for automatic orientation</li></ul>
	 * @param string $unit User measure unit. Possible values are:<ul><li>pt: point</li><li>mm: millimeter (default)</li><li>cm: centimeter</li><li>in: inch</li></ul><br />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.
	 * @param mixed $format The format used for pages. It can be either: one of the string values specified at getPageSizeFromFormat() or an array of parameters specified at setPageFormat().
	 * @param boolean $unicode TRUE means that the input text is unicode (default = true)
	 * @param boolean $diskcache if TRUE reduce the RAM memory usage by caching temporary data on filesystem (slower).
	 * @param String $encoding charset encoding; default is UTF-8
	 * @access public

	 * The method can be called before the first page is created and the font is retained from page to page.
	 * If you just wish to change the current font size, it is simpler to call SetFontSize().
	 * Note: for the standard fonts, the font metric files must be accessible. There are three possibilities for this:<ul><li>They are in the current directory (the one where the running script lies)</li><li>They are in one of the directories defined by the include_path parameter</li><li>They are in the directory defined by the K_PATH_FONTS constant</li></ul><br />

It can be either a name defined by AddFont() or one of the standard Type1 families (case insensitive):<ul><li>times (Times-Roman)</li><li>timesb (Times-Bold)</li><li>timesi (Times-Italic)</li><li>timesbi (Times-BoldItalic)</li><li>helvetica (Helvetica)</li><li>helveticab (Helvetica-Bold)</li><li>helveticai (Helvetica-Oblique)</li><li>helveticabi (Helvetica-BoldOblique)</li><li>courier (Courier)</li><li>courierb (Courier-Bold)</li><li>courieri (Courier-Oblique)</li><li>courierbi (Courier-BoldOblique)</li><li>symbol (Symbol)</li><li>zapfdingbats (ZapfDingbats)</li></ul> It is also possible to pass an empty string. In that case, the current family is retained.
	 * @param string $style Font style. Possible values are (case insensitive):<ul><li>empty string: regular</li><li>B: bold</li><li>I: italic</li><li>U: underline</li><li>D: line trough</li><li>O: overline</li></ul> or any combination. The default value is regular. Bold and italic styles do not apply to Symbol and ZapfDingbats basic fonts or other fonts when not defined.
	 * @param float $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
	 * @param string $fontfile The font definition file. By default, the name is built from the family and style, in lower case with no spaces.

	 * @param float $h Cell minimum height. The cell extends automatically if needed.
	 * @param string $txt String to print

	 * @param string $align Allows to center or align the text. Possible values are:<ul><li>L or empty string: left align</li><li>C: center</li><li>R: right align</li><li>J: justification (default value when $ishtml=false)</li></ul>
	 * @param boolean $fill Indicates if the cell background must be painted (true) or transparent (false).

	 * @param float $x x position in user units
	 * @param float $y y position in user units

	 * @param boolean $ishtml set to true if $txt is HTML content (default = false).
	 * @param boolean $autopadding if true, uses internal padding and automatically adjust it to account for line width.
	 * @param float $maxh 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.
