It gets its * name from the new DomDocument PHP5 extension. Source HTML is first * parsed by a DomDocument object. Dompdf takes the resulting DOM tree and * attaches a {@link Frame} object to each node. {@link Frame} objects store * positioning and layout information and each has a reference to a {@link * Style} object. * * Style information is loaded and parsed (see {@link Stylesheet}) and is * applied to the frames in the tree by using XPath. CSS selectors are * converted into XPath queries, and the computed {@link Style} objects are * applied to the {@link Frame}s. * * {@link Frame}s are then decorated (in the design pattern sense of the * word) based on their CSS display property ({@link * http://www.w3.org/TR/CSS21/visuren.html#propdef-display}). * Frame_Decorators augment the basic {@link Frame} class by adding * additional properties and methods specific to the particular type of * {@link Frame}. For example, in the CSS layout model, block frames * (display: block;) contain line boxes that are usually filled with text or * other inline frames. The Block therefore adds a $lines * property as well as methods to add {@link Frame}s to lines and to add * additional lines. {@link Frame}s also are attached to specific * AbstractPositioner and {@link AbstractFrameReflower} objects that contain the * positioining and layout algorithm for a specific type of frame, * respectively. This is an application of the Strategy pattern. * * Layout, or reflow, proceeds recursively (post-order) starting at the root * of the document. Space constraints (containing block width & height) are * pushed down, and resolved positions and sizes bubble up. Thus, every * {@link Frame} in the document tree is traversed once (except for tables * which use a two-pass layout algorithm). If you are interested in the * details, see the reflow() method of the Reflower classes. * * Rendering is relatively straightforward once layout is complete. {@link * Frame}s are rendered using an adapted {@link Cpdf} class, originally * written by Wayne Munro, http://www.ros.co.nz/pdf/. (Some performance * related changes have been made to the original {@link Cpdf} class, and * the {@link Dompdf\Adapter\CPDF} class provides a simple, stateless interface to * PDF generation.) PDFLib support has now also been added, via the {@link * Dompdf\Adapter\PDFLib}. * * * @package dompdf */ class Dompdf { /** * Version string for dompdf * * @var string */ private $version = 'dompdf'; /** * DomDocument representing the HTML document * * @var DOMDocument */ private $dom; /** * FrameTree derived from the DOM tree * * @var FrameTree */ private $tree; /** * Stylesheet for the document * * @var Stylesheet */ private $css; /** * Actual PDF renderer * * @var Canvas */ private $canvas; /** * Desired paper size ('letter', 'legal', 'A4', etc.) * * @var string|float[] */ private $paperSize; /** * Paper orientation ('portrait' or 'landscape') * * @var string */ private $paperOrientation = "portrait"; /** * Callbacks on new page and new element * * @var array */ private $callbacks = []; /** * Experimental caching capability * * @var string */ private $cacheId; /** * Base hostname * * Used for relative paths/urls * @var string */ private $baseHost = ""; /** * Absolute base path * * Used for relative paths/urls * @var string */ private $basePath = ""; /** * Protocol used to request file (file://, http://, etc) * * @var string */ private $protocol = ""; /** * The system's locale * * @var string */ private $systemLocale = null; /** * The system's mbstring internal encoding * * @var string */ private $mbstringEncoding = null; /** * The system's PCRE JIT configuration * * @var string */ private $pcreJit = null; /** * The default view of the PDF in the viewer * * @var string */ private $defaultView = "Fit"; /** * The default view options of the PDF in the viewer * * @var array */ private $defaultViewOptions = []; /** * Tells whether the DOM document is in quirksmode (experimental) * * @var bool */ private $quirksmode = false; /** * Local file extension whitelist * * File extensions supported by dompdf for local files. * * @var array */ private $allowedLocalFileExtensions = ["htm", "html"]; /** * @var array */ private $messages = []; /** * @var Options */ private $options; /** * @var FontMetrics */ private $fontMetrics; /** * The list of built-in fonts * * @var array * @deprecated */ public static $native_fonts = [ "courier", "courier-bold", "courier-oblique", "courier-boldoblique", "helvetica", "helvetica-bold", "helvetica-oblique", "helvetica-boldoblique", "times-roman", "times-bold", "times-italic", "times-bolditalic", "symbol", "zapfdinbats" ]; /** * The list of built-in fonts * * @var array */ public static $nativeFonts = [ "courier", "courier-bold", "courier-oblique", "courier-boldoblique", "helvetica", "helvetica-bold", "helvetica-oblique", "helvetica-boldoblique", "times-roman", "times-bold", "times-italic", "times-bolditalic", "symbol", "zapfdinbats" ]; /** * Class constructor * * @param Options|array|null $options */ public function __construct($options = null) { if (isset($options) && $options instanceof Options) { $this->setOptions($options); } elseif (is_array($options)) { $this->setOptions(new Options($options)); } else { $this->setOptions(new Options()); } $versionFile = realpath(__DIR__ .
