Storing "X number of pixels" is done by outputting your RGB triplets
backwards -- i.e. BGR triplets. SImply put, fill your bitmap info
structure, write the header, and write out your pixels... however many or
few you want. 

I can mail you the format specs if you like, or paraphrase them for easier
coding. There's a lot of if/but/maybe/possibly in the full specification,
due to the enhancements made to BMP for the DIB format, but if you just
want to dump raw data to the file you don't need *all* the specs.
As the fire burneth a wood, and the flame setteth the mountains on fire; 
So persecute them with thy tempest, and make them afraid with thy storm.
