Please provide an *image* showing what you expect. Previous Comments: ------------------------------------------------------------------------ [2007-01-18 17:56:25] henus at mail dot ru i create black image and overlay it by colorized white-truecolor-png24-image ( http://fort-ross.ru/henus/gd/mask.png ) the result of colorize like: imagefilter($mask, IMG_FILTER_COLORIZE, -255, -255, -255); is image: http://www.fort-ross.ru/henus/gd/result_incorrect.png which contain artefacts... also, the result of such script ( http://fort-ross.ru/henus/gd/demo2.phps ) is: is truecolor - 1 before - Array ( [red] => 255 [green] => 255 [blue] => 255 [alpha] => 63 ) wrong result, using filter - Array ( [red] => 126 [green] => 126 [blue] => 126 [alpha] => 31 ) wrong result, using imagecolorallocatealpha and imagesetpixel - Array ( [red] => 126 [green] => 126 [blue] => 126 [alpha] => 31 ) correct result, using imagefill, imagecolorallocatealpha and imagesetpixel - Array ( [red] => 0 [green] => 0 [blue] => 0 [alpha] => 63 ) I.e. colorizing pixel ( [red] => 255 [green] => 255 [blue] => 255 [alpha] => 63 ) to black should be with ( [red] => 0 [green] => 0 [blue] => 0 [alpha] => 63 ), not ( [red] => 126 [green] => 126 [blue] => 126 [alpha] => 31 ) ------------------------------------------------------------------------ [2007-01-18 15:22:49] [EMAIL PROTECTED] Can you provide an image to show what you expect? I did not check your script but having an image will help to really understand what you are trying to achieve. By the way, filters work only with truecolor images, allocate will never fail. ------------------------------------------------------------------------ [2007-01-18 14:26:28] [EMAIL PROTECTED] >...should be without alpha... Could you plz elaborate? A unified diff would explain it much better, btw. ------------------------------------------------------------------------ [2007-01-18 14:23:38] henus at mail dot ru php-5.2.0\ext\gd\libgd\gd.c Lines 3682-3685: new_pxl = gdImageColorAllocateAlpha(src, (int)r, (int)g, (int)b, a); if (new_pxl == -1) { new_pxl = gdImageColorClosestAlpha(src, (int)r, (int)g, (int)b, a); } ....should be without alpha... ------------------------------------------------------------------------ [2007-01-18 11:03:15] henus at mail dot ru My mistake... correct 12 line in Reproduce code: imagefilter($mask, IMG_FILTER_COLORIZE, -255, -255, -255); ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
