- // Description : This is a PHP class for generating PDF documents without

- //
- // NOTE:
- // This class was originally derived in 2002 from the Public

- // 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;

- /**
- * 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
- * @see getPageSizeFromFormat(), setPageFormat()
