Bitmap information structure.
Each bit plane logically contains (cx * cy * cBitCount) bits, although the actual length can be greater because of padding.
See also BITMAPINFO2, which is preferred.
typedef struct _BITMAPINFO { ULONG cbFix; /* Length of fixed portion of structure. */ USHORT cx; /* Bitmap width in pels. */ USHORT cy; /* Bitmap height in pels. */ USHORT cPlanes; /* Number of bit planes. */ USHORT cBitCount; /* Number of bits per pel within a plane. */ RGB argbColor[1]; /* Array of RGB values. */ } BITMAPINFO; typedef BITMAPINFO * PBITMAPINFO ;
