Just upgraded from PHP 5.1.4 to 5.2.11 Using 5.1.4 the function would correctly position a line at the request angle with 5.2.11 zero is always used. the start and end must be at least 1 degree different to produce the correct result. Reproduce code: --------------- --- From manual page: function.imagefilledarc#Description --- <?php $img = imagecreate(200, 200); $white = imagecolorallocate($img, 255, 255, 255); $blue = imagecolorallocate($img, 153, 204, 255); $black = imagecolorallocate($img, 0, 0, 0); imagefilledarc($img, 100, 100, 175, 175,0,360, $blue,IMG_ARC_PIE); imagefilledarc($img, 100, 100, 175, 175, 150,150, $black,IMG_ARC_PIE|IMG_ARC_NOFILL |IMG_ARC_EDGED); header("Content-type: image/png"); imagepng($img); imagedestroy($img); ?> Expected result: ---------------- blue circle with black line drawn at 150degrees Actual result: -------------- blue circle with black line drawn at 0degrees ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=50036&edit=1
