/**
|
|
* pdflib.php - Moodle PDF library
|
|
*
|
|
* We currently use the TCPDF library by Nicola Asuni.
|
|
*
|
|
* The default location for fonts that are included with TCPDF is
|
|
* lib/tcpdf/fonts/. If $CFG->datadir.'/fonts/' exists, this directory
|
|
* will be used instead of lib/tcpdf/fonts/. If there is only one font
|
|
* present in $CFG->datadir.'/fonts/', the font is used as the default
|
|
* font.
|
|
*
|
|
* See lib/tcpdf/fonts/README for details on how to convert fonts for use
|
|
* with TCPDF.
|
|
*
|
|
* Example usage:
|
|
* <code>
|
|
* $doc = new pdf;
|
|
* $doc->setPrintHeader(false);
|
|
* $doc->setPrintFooter(false);
|
|
* $doc->AddPage();
|
|
* $doc->Write(5, 'Hello World!');
|
|
* $doc->Output();
|
|
* </code>
