No one can give you any help because your question is vague. Read the "Posting Guidelines: Read this before you post" link, it's not just for decoration on these pages because it'll guide you in how to make a post that'll properly define your question.

i don't know the actual method, but here's some help:

at the top of the file, there is a header for the file, (only in 2,16 and 256 color bmps. In 16 bit, the data for the points are the color.) also the bitmap is loaded from bottom to top, left to right (i think.)

go here:

http://www.wotsit.org/

its got info on a crap load of file formats. dont know what its missed but its got some stuff on bitmaps that would help. you basically just use the standard c++ fstream functions to do it you just have to know the order and where in the file to read to find everything you need.

Say, mash potatoes, check out: 'x2ftp.oulu.fi' under '/pub/msdos/programming/formats' inside the zip file 'BMP.ZIP'. This sheds light on how the internal workings of BMP files.
