Detailed Description

Implementation of CFile handling Windows Bitmaps.

In order to support operations on bitmaps with different color bitcounts different implementations of CPixelFormat are used. These classes are allowed to modify the bitmap headers and pixelbuffer directly.

On error CFile::FileError is thrown.
