I don't see why not.

If you want to, say, take a 24-bit or 32-bit and treat it as an 
8-bit image, you'll probably want to actually do a conversion 
rather than a simulation. In which case you'd probably be better 
off just using an existing C library like FreeImage. You can find 
a binding here:

Otherwise, you'll want to hit up a graphics programming forum for 
resources on image conversion. Two possibilities:
