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

+     * A PHP class to provide the basic functionality to create a pdf document without
+     * any requirement for additional modules.
+     *
+     * Note that the companion class CezPdf can be used to extend this class and dramatically
+     * simplify the creation of documents.
+     *
+     * Extended by Orion Richardson to support Unicode / UTF-8 characters using
+     * TCPDF and others as a guide.
+     *
+     * IMPORTANT NOTE
+     * there is no warranty, implied or otherwise with this software.
+     *
+     * LICENCE
+     * This code has been placed in the Public Domain for all to enjoy.

+     * @version  009
+     * @package  Cpdf
+     *
+     * Changes
+     * @contributor Helmut Tischer <htischer@weihenstephan.org>
+     * @version 0.5.1.htischer.20090507
+     * - On multiple identical png and jpg images, put only one copy into the pdf file and refer to it.
+     *   This reduces file size and rendering time.
+     * - Allow font metrics cache to be a different folder as the font metrics. This allows a read only installation.
+     * - Allow adding images directly from a gd object. This increases performance by avoiding temporary files.
+     * - On png image files remove alpa channel to allow display of typical png files in pdf.
+     * - On addImage avoid temporary file. Todo: Duplicate Image (currently not used)
+     * - Add a check function, whether image is already cached, This avoids double creation by caller which saves
+     *   CPU time and memory.
+     * @contributor Helmut Tischer <htischer@weihenstephan.org>
+     * @version dompdf_trunk_with_helmut_mods.20090524
+     * - Allow temp and fontcache folders to be passed in by class creator
+     * @version dompdf_trunk_with_helmut_mods.20090528
+     * - typo 'decent' instead of 'descent' at various locations made getFontDescender worthless
