// 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;
