Hello everybody,
It seems to me that someone posted a method of converting hsv to rgb
using only functions.
I can't find it or I've had a dream ?
Thank you for your memories ;)

Ho yes, Trevor G Quayle of course... but hsl, not hsv.

Thank you for your memory.

Finally, I found the time to write my functions for HSL and HSV to RGB
conversations.
If anyone's interested, I've prepared a small zip (4k) containing the
library (.inc) and a test sdl (.pov).
Don't hesitate to ask.
In any case, I'll put it on my site.

I found this lurking in an old 3.7 include folder.
Pretty sure it's not mine.
Might be yours.
Might be TOK's or Ingo's, or someone else's.
I'll have to keep looking to see where the heck mine is, and what it's called.

This is the job of Trevor G Quayle.
