You're right at present we handle only rgb images via PIL. As I
understand it PIL can handle other kinds of things including CMYK and I
guess you are right to say that converting to RGB would be wrong for
those images.

At present I'm sure we aren't planning an immediate effort to add cmyk
images, but for JPEGS I see that we allow for the colorspace to default
to 'DeviceCMYK' after testing for 1 or 3 color components.

When loading from a bitmap type image I guess we ought to allow for
testing the number of image components & masking & etc etc etc sigh :(
