Basically it works as if div=1 and offset=0. The formula for the conversion has been chacked in photoshop, and should work as intended. Reproduce code: --------------- <?PHP $img=imagecreatefromjpeg("image.jpg"); imageconvolution($img,array(array(-1,-1,-1),array(-1,16,-1),array(-1,-1,-1)), 8,0); imagejpeg($img,"test.jpg"); ?> Expected result: ---------------- Sharpened image that retains normal color etc. Actual result: -------------- Eccsessivly sharpened image, mostly white with some color in the high-contrast areas. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=34980&edit=1
