|
---|
| 43 | * DOMPDF - PHP5 HTML to PDF renderer
|
---|
| 44 | *
|
---|
| 45 | * DOMPDF loads HTML and does its best to render it as a PDF. It gets its
|
---|
| 46 | * name from the new DomDocument PHP5 extension. Source HTML is first
|
---|
| 47 | * parsed by a DomDocument object. DOMPDF takes the resulting DOM tree and
|
---|
| 48 | * attaches a {@link Frame} object to each node. {@link Frame} objects store
|
---|
| 49 | * positioning and layout information and each has a reference to a {@link
|
---|
| 50 | * Style} object.
|
---|
| 51 | *
|
---|
| 52 | * Style information is loaded and parsed (see {@link Stylesheet}) and is
|
---|
| 53 | * applied to the frames in the tree by using XPath. CSS selectors are
|
---|
| 54 | * converted into XPath queries, and the computed {@link Style} objects are
|
---|
| 55 | * applied to the {@link Frame}s.
|
---|
| 56 | *
|
---|
| 57 | * {@link Frame}s are then decorated (in the design pattern sense of the
|
---|
| 58 | * word) based on their CSS display property ({@link
|
---|
| 59 | * http://www.w3.org/TR/CSS21/visuren.html#propdef-display}).
|
---|
| 60 | * Frame_Decorators augment the basic {@link Frame} class by adding
|
---|
| 61 | * additional properties and methods specific to the particular type of
|
---|
| 62 | * {@link Frame}. For example, in the CSS layout model, block frames
|
---|
| 63 | * (display: block;) contain line boxes that are usually filled with text or
|
---|
| 64 | * other inline frames. The Block_Frame_Decorator therefore adds a $lines
|
---|
| 65 | * property as well as methods to add {@link Frame}s to lines and to add
|
---|
| 66 | * additional lines. {@link Frame}s also are attached to specific
|
---|
| 67 | * Positioner and {@link Frame_Reflower} objects that contain the
|
---|
| 68 | * positioining and layout algorithm for a specific type of frame,
|
---|
| 69 | * respectively. This is an application of the Strategy pattern.
|
---|
| 70 | *
|
---|
| 71 | * Layout, or reflow, proceeds recursively (post-order) starting at the root
|
---|
| 72 | * of the document. Space constraints (containing block width & height) are
|
---|
| 73 | * pushed down, and resolved positions and sizes bubble up. Thus, every
|
---|
| 74 | * {@link Frame} in the document tree is traversed once (except for tables
|
---|
| 75 | * which use a two-pass layout algorithm). If you are interested in the
|
---|
| 76 | * details, see the reflow() method of the Reflower classes.
|
---|
| 77 | *
|
---|
| 78 | * Rendering is relatively straightforward once layout is complete. {@link
|
---|
| 79 | * Frame}s are rendered using an adapted {@link Cpdf} class, originally
|
---|
| 80 | * written by Wayne Munro, http://www.ros.co.nz/pdf/. (Some performance
|
---|
| 81 | * related changes have been made to the original {@link Cpdf} class, and
|
---|
| 82 | * the {@link CPDF_Adapter} class provides a simple, stateless interface to
|
---|
| 83 | * PDF generation.) PDFLib support has now also been added, via the {@link
|
---|
| 84 | * PDFLib_Adapter}.
