I was tried this with grayscale images. Second color in noise was exactly same as source color, but with RGB channels lowered by 1. When the source image was filled with color, which had RGB channels values equal to power of 2 (0,1,2,4,8,16,32,64,128) the noise disappears. Reproduce code: --------------- $im = imagecreatetruecolor(1045,600); $back = imagecolorallocate($im, 100, 100, 100); imagefill($im, 0, 0, $back); $im2 = imagecreatetruecolor(383,220); imagecopyresampled($im2,$im,0,0,0,0,383,220,1045,600); imagepng($im2); Expected result: ---------------- PNG file filled with color 100,100,100(RGB) Actual result: -------------- PNG file filled with color noise of 100,100,100(RGB) and 99,99,99(RGB) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41820&edit=1
