[lug] gimp suggestions?

[D. Stimits]

I'm looking for the most direct way to export, from gimp (or some other 
common tool), the RGB or RGBA data from a color image as hex data. E.G., 
for red => ff0000, green => 00ff00, blue => 0000ff. I'm experimenting 
with some of the file formats which come close, but for example the xpm 
format seems to do some encoding. Can anyone give me an idea of some 
simple way to take an image and save it as just RGB/RGBA pixel data in a 
hex string, with no compression or other information?
