note 51315 added to function.pdf-begin-template

A template is an "image" that can be drawn like a normal image, but is composed of pdflib-commands, directly specified in the program. Templates can be used if you have a graphical pattern that you want to repeat several times - i.e. a logo repeated on top of each page. As the pdf-commands that draws the template are only included once in the file even if the template is shown several times, you can save a lot of space. This program draws a simple fractal without the use of templates: <?php function drawmenger(&$pdf,$x,$y,$w,$level) { if($level===0) { pdf_rect($pdf,$x,$y,$w,$w); pdf_fill($pdf); return; } $w /= 3; for($i=0; $i<3; $i++) for($j=0; $j<3; $j++) if($i!=1 || $j!=1) drawmenger($pdf,$x+$w*$j,$y+$w*$i,$w,$level-1); } $pdf = pdf_new(); pdf_open_file($pdf); pdf_begin_page($pdf, 595, 421); drawmenger($pdf,50,50,300,6); header('Content-type: application/pdf'); header('Content-disposition: inline; filename=test.pdf'); header('Content-length: ' . strlen($data)); echo $data; pdf_end_page($pdf); pdf_close($pdf); pdf_delete($pdf); ?> The file created is almost 1Mb. Using templates to store the intermediate results reduces the filesize to a mere 3kb. <?php function drawmenger(&$pdf,$x,$y,$w,$level) { if($level===0) { pdf_rect($pdf,$x,$y,$w,$w); pdf_fill($pdf); return; } $w /= 3; for($i=0; $i<3; $i++) for($j=0; $j<3; $j++) if($i!=1 || $j!=1) drawmenger($pdf,$x+$w*$j,$y+$w*$i,$w,$level-1); } $pdf = pdf_new(); pdf_open_file($pdf); pdf_begin_page($pdf, 595, 421); drawmenger($pdf,50,50,300,6); header('Content-type: application/pdf'); header('Content-disposition: inline; filename=test.pdf'); header('Content-length: ' . strlen($data)); echo $data; pdf_end_page($pdf); pdf_close($pdf); pdf_delete($pdf); ?> ---- Manual Page -- http://www.php.net/manual/en/function.pdf-begin-template.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+51315 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+51315&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+51315&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+51315&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+51315&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+51315&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+51315&report=yes Search -- http://master.php.net/manage/user-notes.php
