[magick-users] Print rgb values for pixels

[Chris And Melinda LaForce]

Hello,
   Can someone give me some direction on how to print out the rgb value for
all the pixels in an image?  I've tried coping the contrast.c example from
ImageMagicks MagickWand C API page which opens an images and iterates
through the pixels, but I'm kind of lost on how to just print the rgb values
out at that point.  Any help or examples would be greatly appreciated.
Thanks,

Chris.
