Put it online somewhere or give link to any png file that produces the same problem. ------------------------------------------------------------------------ [2003-07-10 05:37:05] eric at pitte dot de Description: ------------ I see a problem with the imagecopymergegray funktion. It does not seems to be possible to make grayscale from a png color image. See my code. Spion.png is a color image and spion2 should be a grayscale one, but the result is also a color picture. Is this problem known ? Reproduce code: --------------- <?php $pic = imageCreateFrompng("spion.png"); imagecopymergegray($pic,$pic,0,0,0,0,500,500,20); imagepng($pic,"spion2.png"); imagedestroy($pic); ?> ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=24585&edit=1
