Uncompressed Graphic Format

[Hardboy]

Hi,

I´m searching for am uncompressed graphic file format. Does anyone know a simple one? I´d prefer a format which stores pixels in RGB.

Thanks!

It really doesn´t matter how supported it is. It´s because I´m testing some compressing techniques, and need some simple format to load and store results in. Documentation and simple layout is most important.
