For anyone suffering from the srcX and srcY bug (some versions of gd ignore them completely - see http://bugs.php.net/bug.php?id=12780 for details), a quick solution is to use this code snippet: <?php function imgcopyresampled(&$dst_img, $src_img, $dst_x, $dst_y, $src_x, $src_y, $dst_w, $dst_h, $src_w, $src_h) { $tmp_img = imagecreatetruecolor($src_w, $src_h); $rv2 = imagecopy($tmp_img, $src_img, 0,0, $src_x, $src_y, $src_w, $src_h); $rv1 = imagecopyresampled($dst_img, $tmp_img, $dst_x,$dst_y, 0,0, $dst_w, $dst_h, $src_w, $src_h); imagedestroy($tmp_img); return($rv1 and $rv2); } ?> By using imagecopy to extract the relevant portion of the source image, it works a lot more quickly than pike's solution below, and also without the extra blur. It may be useful to use override_function in existing projects, although I have not tested this myself. ---- Server IP: 195.221.21.36 Probable Submitter: 83.157.38.138 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.imagecopyresampled.php Edit -- http://master.php.net/note/edit/66054 Del: integrated -- http://master.php.net/note/delete/66054/integrated Del: useless -- http://master.php.net/note/delete/66054/useless Del: bad code -- http://master.php.net/note/delete/66054/bad+code Del: spam -- http://master.php.net/note/delete/66054/spam Del: non-english -- http://master.php.net/note/delete/66054/non-english Del: in docs -- http://master.php.net/note/delete/66054/in+docs Del: other reasons-- http://master.php.net/note/delete/66054 Reject -- http://master.php.net/note/reject/66054 Search -- http://master.php.net/manage/user-notes.php
