Image Color Downsizing

[Rick Harrison]

Hi again,

Well, the news isn't as good as I'd hoped.

Apparently color downsizing doesn't go down to 16 colors
for some reason.  Even if I use a ColorList of 16 colors it
won't stick to the ones I've assigned.  Does anyone have
a work around?

Let me know.

Thanks,

Rick

The image will be color-matched to this palette before export. If colorList is not specified, a 256 entry palette will be generated.
