I too would very much like some info on this .. preferably some C source
code eg:

struct HSV * rgb_to_hsv_conv(struct RGB *);

type functions. The defintions of HSV RGB etc etc blah are all well documented
in numerous graphics books, but few give details on conversion techniques,
most stopping short of the trivial RGB to intensity conversion. Someone
must have some code for this, which is not so large that it can't be posted.

Please no flames, just put it down to being young and impetuous,

thank's in advance,

Ashley.
