// 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 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 $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.
