Rajesh,

The Platform SDK has the structures involved, but the nature of the data bits depends on the number of colors. For example, a 16 color bitmap contains the offset into a structure called an RGBQuad array in four bits in each byte of the file. A 256 color bitmap contains the offset in each byte. A 24 bit color bitmap is entirely different in that theres no array, and the colors are as specified in each DWORD. That's why I asked the question.
