Converting a pixel value to component RGB values

[Arthur Jerijian <lightmanaj earthlink net>]

Hi all,

I am writing a function which will copy a GdkImage to an image of another
format. As such, I need to derive the red, green, and blue component values
from the pixel value returned by gdk_image_get_pixel. Is this just a matter of
shifting bits? How would I do it if the GdkImage is a PseudoColor image?

Thanks,
