note 116106 added to function.imagecrop

Here is my quick implementation for older versions of PHP: if(!function_exists('imagecrop')) { function imagecrop($image, array $rect) { $radiusX = $rect['width'] / 2; $radiusY = $rect['height'] / 2; $center_x = $rect['x'] + $radiusX - 1; $center_y = $rect['y'] + $radiusY - 1; $radiusXsqr = $radiusX * $radiusX; $radiusYsqr = $radiusY * $radiusY; $max_x = min($image_width = imagesx($image), $rect['x'] + $rect['width']) - 1; $max_y = min($image_height = imagesy($image), $rect['y'] + $rect['height']) - 1; $copy = imagecreatetruecolor($image_width, $image_height); imagecopy($copy, $image, 0, 0, 0, 0, $image_width, $image_height); //make copy of image imagefilledrectangle($image, 0, 0, $image_width - 1, $image_height - 1, imagecolorallocate($image, 0, 0, 0)); //fill the image with black color imagesavealpha($image, true); imagefill($image, 0, 0, imagecolorallocatealpha($image, 0, 0, 0, 127)); //replace the black with transparent //copy back to image only pixels inside ellipse for ($x = max($rect['x'], 0); $x <= $max_x; $x++) { for ($y = max($rect['y'], 0); $y <= $max_y; $y++) { if(pow($x - $center_x, 2) / $radiusXsqr + pow($y - $center_y, 2) / $radiusYsqr <= 1) { //pixel is inside of ellipse imagesetpixel($image, $x, $y, imagecolorat($copy, $x, $y)); //copy the pixel } } } imagedestroy($copy); } } ---- Server IP: 72.52.91.14 Probable Submitter: 109.105.44.71 ---- Manual Page -- http://php.net/manual/en/function.imagecrop.php Edit -- https://master.php.net/note/edit/116106 Del: integrated -- https://master.php.net/note/delete/116106/integrated Del: useless -- https://master.php.net/note/delete/116106/useless Del: bad code -- https://master.php.net/note/delete/116106/bad+code Del: spam -- https://master.php.net/note/delete/116106/spam Del: non-english -- https://master.php.net/note/delete/116106/non-english Del: in docs -- https://master.php.net/note/delete/116106/in+docs Del: other reasons-- https://master.php.net/note/delete/116106 Reject -- https://master.php.net/note/reject/116106 Search -- https://master.php.net/manage/user-notes.php
