|

7 | * A PHP class to provide the basic functionality to create a pdf document without
|
---|
8 | * any requirement for additional modules.
|
---|
9 | *
|
---|
10 | * Note that they companion class CezPdf can be used to extend this class and dramatically
|
---|
11 | * simplify the creation of documents.
|
---|
12 | *
|
---|
13 | * Extended by Orion Richardson to support Unicode / UTF-8 characters using
|
---|
14 | * TCPDF and others as a guide.

28 | * Changes
|
---|
29 | * @contributor Helmut Tischer <htischer@weihenstephan.org>
|
---|
30 | * @version 0.5.1.htischer.20090507
|
---|
31 | * - On multiple identical png and jpg images, put only one copy into the pdf file and refer to it.
|
---|
32 | * This reduces file size and rendering time.
|
---|
33 | * - Allow font metrics cache to be a different folder as the font metrics. This allows a read only installation.
|
---|
34 | * - Allow adding images directly from a gd object. This increases performance by avoiding temporary files.
|
---|
35 | * - On png image files remove alpa channel to allow display of typical png files in pdf.
|
---|
36 | * - On addImage avoid temporary file. Todo: Duplicate Image (currently not used)
|
---|
37 | * - Add a check function, whether image is already cached, This avoids double creation by caller which saves
|
---|
38 | * CPU time and memory.
|
---|
39 | * @contributor Helmut Tischer <htischer@weihenstephan.org>
|
---|
40 | * @version dompdf_trunk_with_helmut_mods.20090524
|
---|
41 | * - Allow temp and fontcache folders to be passed in by class creator
|
---|
42 | * @version dompdf_trunk_with_helmut_mods.20090528
|
---|
43 | * - typo 'decent' instead of 'descent' at various locations made getFontDescender worthless
