While basic dash patters can be set with pdf_setdash() , sometimes a more complex pattern is required. By passing an array of alternating bacl and white dash values to pdf_setpolydash() , a more complex pattern can be achieved.
All array values must be positive and have non-zero values with a maximum of 8 elements in the array.
<?php // create new document $pdf = pdf_new(); pdf_open_file($pdf); pdf_begin_page($pdf, 500, 700); // set widening black dash $dash = array(1.2, 0.2, 2.8); // set line dash type pdf_setlinewidth($pdf,2); pdf_setpolydash($pdf, $dash); // draw dashed lines pdf_moveto($pdf, 200, 600); pdf_lineto($pdf, 250, 500); pdf_lineto($pdf, 300, 600); pdf_stroke($pdf); pdf_end_page($pdf); pdf_close($pdf); // output document $data = pdf_get_buffer($pdf); header("Content-type: application/pdf"); header("Content-disposition: inline; filename=test.pdf"); header("Content-length: " . strlen($data)); echo $data; ?>
