note 39781 added to function.imagettfbbox

As "oliver dot martin at onemail dot at" noted above, imagettfbbox() does not work correctly in php 4.3.4. To remedy this, I've written a short function that uses trig to calculate the bounding box from rotating a non-rotated piece of text. Hopefully, this comment will be obsolete soon, but for now, ... function imagettfbbox_t($size, $angle, $fontfile, $text) { // compute size with a zero angle $coords = imagettfbbox($size, 0, $fontfile, $text); // convert angle to radians $a = $angle * M_PI / 180; // compute some usefull values $ca = cos($a); $sa = sin($a); $ret = array(); // perform transformations for($i = 0; $i < 7; $i += 2) { $ret[$i] = round($coords[$i] * $ca + $coords[$i+1] * $sa); $ret[$i+1] = round($coords[$i+1] * $ca - $coords[$i] * $sa); } return $ret; } ---- Manual Page -- http://www.php.net/manual/en/function.imagettfbbox.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+39781 Delete -- http://master.php.net/manage/user-notes.php?action=delete+39781&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+39781&report=yes Search -- http://master.php.net/manage/user-notes.php
