Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php imagecopyresampled uses a resampling using weight of each original pixels in the destination image. That means even by resizing by a ratio of 0.99, you will have part of the image that will differ, in your case the edges of your square. --Pierre Previous Comments: ------------------------------------------------------------------------ [2004-10-28 11:02:46] lunter at interia dot pl Description: ------------ Imagecopyresampled function bug: Original image: Any one-color square.
