[TYPO3] GIFBUILDER and dithering

[Peter Klein]

Has anyone here a lot of experince with GIFBUILDER?

I have a gradient GIF image with 256 colors. On that I write some text using 
GIFBUILDER, and output the new image on my TYPO3 site.
But now the colors of the image is reduced to 78 colors and the image is 
dithered, EVEN if I set "reduceColors=255" and/or "quality=100"
I have tried all combinations of settings I can think of to no avail :(
