Retrieve pixel color

[halfbarrel]

Hello,
What I would like to do is pass an image file into a c program as an argument on my linux box and then loop through it's pixels to see what color they are. Does someone know what the code is to get a pixel(specifically the pixels color) and what header/s would have to be included.
Thanks,

That would depend entirely on the format of the image file.
BMP, PNG, GIF, JPG - They're all different.
