When you create that image from the original GIF, you are inheriting the COLOR PALLETTE that is in that GIF. The original GIF maker may well have restricted you to, say, 4 colors, in order to make the GIF really small, none of which colors are white. I'm assuming you are using http://php.net/imagecolorallocate already, and are trying to use 255, 255, 255 to get white. However, if the pallette is only allowed to have 4 colors, and they are already in use, you ain't gonna get your white color -- Your imagecolorallocate will return -1 -- Which shouldn't work too good at all in the rest of your script... So I'm a bit confused exactly how you got the gray color. That said, here are some possible ideas. #1. Check all your return codes from all your functions. If you *think* you are getting a color, but you get -1, something went wrong. Catch it, deal with it, and do something smart about it. #2. Use http://php.net/imagecreatetruecolor to make your image. Then use http://php.net/imagecreatefromgif to pull in the GIF Then use http://php.net/imagecopy to *copy* the GIF into your image. #3. There are PHP functions to examine the pallette. Use them. Figure out where the gray is coming from and why. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
