Re: rgb -> hsv and back

[Stephane Delcroix <stephane delcroix org>]

Hey,

1. no, there's no doc but the code itself...
2. AFAIK, (Gdk)pixbuf doesn't support HSV. so "converting a RGB pixbuf
to HSV" doesn't make a lot of sense
so, you'll probably have to do the RGB->HSV conversion (and back)
yourself, but you might find some converter already available on the
web. My .02€ tip: don't do that in managed code, it'll be way too slow.
