If your PNG contains 'true colors', GD 1.x can't handle them. ------------------------------------------------------------------------ [2002-02-03 16:19:53] dirk.schaeck@system-interface.de Hello, i get a png image whith more than 16 color whith the function ImageCreateFromPNG and i send it to the Browser. If i compare the color from the original and from the Picture on browser i see the first 16 color correctly but the next colors behind are a repeating colorset. ( i think this are the default color from the gd lib). thanks dirk ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=15360&edit=1
