Previous Comments: ------------------------------------------------------------------------ [2006-08-28 14:36:50] toby@php.net Description: ------------ 1. Allocate an image resource $a. 2. Resample (scale) $a to a second resource $b. 3. Destroy $a. 4. Assign $a = $b. 5. Resample (crop) $a to a third resource $c. 6. Destroy $a. 7. Assign $a = $c. For step 5 the initially allocated resource is used instead of the originally resampled one. Reproduce code: --------------- <?php // http://schlitt.info/misc/gd/test_original.jpg $res_1 = imagecreatefromjpeg( "test_original.jpg" ); $res_2 = imagecreatetruecolor( 200, 151 ); // Scale the image to 200x151 $res = imagecopyresampled( $res_2, // dst_img $res_1, // res_img 0, // dst_x 0, // dst_y 0, // src_x 0, // src_y 200, // dst_width 151, // dst_height 150, // src_width 113 // src_height ); // http://schlitt.info/misc/gd/test_scaled.jpg imagejpeg( $res_2, "test_scaled.jpg" ); imagedestroy( $res_1 ); $res_1 = $res_2; $res_3 = imagecreatetruecolor( 100, 100 ); // Crop the image to 100x100 selecting 50x150+50x150 $res = imagecopyresampled( $res_3, // dst_img $res_1, // res_img 0, // dst_x 0, // dst_y 50, // src_x 50, // src_y 100, // dst_width 100, // dst_height 150, // src_width 150 // src_height ); // http://schlitt.info/misc/gd/test_cropped.jpg imagejpeg( $res_3, "test_cropped.jpg" ); imagedestroy( $res_1 ); $res_1 = $res_3; // http://schlitt.info/misc/gd/test_final.jpg imagejpeg( $res_1, "test_final.jpg" ); ?> Expected result: ---------------- test_cropped.jpg should be a cropped version of test_scaled.php Actual result: -------------- test_cropped.jpg is a cropped version of test_original.jpg ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=38627&edit=1
