// 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;

     * 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 />
     * @param string $family Family font. 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 mixed $subset if true embedd only a subset of the font (stores only the information related to the used characters); if false embedd full font; if 'default' uses the default value set using setFontSubsetting(). This option is valid only for TrueTypeUnicode fonts. If you want to enable users to change the document, set this parameter to false. If you subset the font, the person who receives your PDF would need to have your same font in order to make changes to your PDF. The file size of the PDF would also be smaller because you are embedding only part of a font.

     * Text can be aligned, centered or justified. The cell block can be framed and the background painted.
     * @param float $w Width of cells. If 0, they extend up to the right margin of the page.
     * @param float $h Cell minimum height. The cell extends automatically if needed.
     * @param string $txt String to print
     * @param mixed $border Indicates if borders must be drawn around the cell. The value can be a number:<ul><li>0: no border (default)</li><li>1: frame</li></ul> or a string containing some or all of the following characters (in any order):<ul><li>L: left</li><li>T: top</li><li>R: right</li><li>B: bottom</li></ul> 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 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 int $ln Indicates where the current position should go after the call. Possible values are:<ul><li>0: to the right</li><li>1: to the beginning of the next line [DEFAULT]</li><li>2: below</li></ul>
     * @param float $x x position in user units
     * @param float $y y position in user units
     * @param boolean $reseth if true reset the last cell height (default true).

     * @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.
     * @param string $valign Vertical alignment of text (requires $maxh = $h > 0). Possible values are:<ul><li>T: TOP</li><li>M: middle</li><li>B: bottom</li></ul>. This feature works only when $ishtml=false.
     * @param boolean $fitcell if true attempt to fit all the text within the cell by reducing the font size.
