First, the K value is stuck at zero no matter what the RGB values are.
Next, the C, M and Y values are integers and not in the value range 0.0 - 1.0.
I have no idea what they mean. They seem to bear no relationship at all to the
proper CMYK values.
I coded an RGB to CMY to CMYK algorithm derived from the formulas found at http://www.easyrgb.com/math.php?MATH=M2#text2 , which seem to be correct.
Is im.convert ('CMYK') broken ? I'd like to use it since this is the only
colorspace conversion available in PIL.Is there any particular reason why conversions to HSV and/or HSL don't exist ?
It would really useful to work with brightness or luminosity directly.
