InitBitMap

Initialize bit map structure with input values.

Initialize various elements in the BitMap structure to correctly reflect depth, width, and height. Must be used before use of BitMap in other graphics calls. The Planes[8] are not initialized and need to be set up by the caller. The Planes table was put at the end of the structure so that it may be truncated to conserve space, as well as extended. All routines that use BitMap should only depend on existence of depth number of bitplanes. The Flags and pad fields are reserved for future use and should not be used by application programs.

bm

pointer to a BitMap structure (gfx.h)

depth

number of bitplanes that this bitmap will have

width

number of bits (columns) wide for this BitMap

height- number of bits (rows) tall for this BitMap
