are bitmap files platform dependant?

Endianness is about how the data is stored in the memory. When you're talking about endianness, you're usually talking about big endian, little endian, and some times mixed endian. There's much more information on Wikipedia.

UPDATE: FREAD AND FWRITE DO NOT COMPENSATE FOR BIG/LITTLE ENDIAN MODE.

And yes, it would affect the data. 0xABCD is not the same as 0xDCBA. I think (but I'm not sure) that fread() and fwrite() take care of that. If you need to use specific data sizes that are cross-platform, instead of using BYTE,WORD,DWORD, and QWORD, use __int8, __int16, __int32, and __int64 (use unsigned prefix if necessary). These are guaranteed to be the same size on any system, indicated by the number after int which is the number of bits.

dargueta, you have the facility to test the bitmaps on different architectures. I think the best way to know if bitmaps depend on the underlined architecture is to test it.

I don't quite get what you mean.

You haven't done this? I mean, create the bitmap on a 16- or 32-bit architecture and try to read it on a different 64-bit architecture.

Um...no. Should I have? As long as one uses the right data type declarations, architecture shouldn't matter.
