Bitmaps represented as strings
The module provides polymorphic support for representation of bitmaps as strings. This module is designed to be most efficient with lazy bytestrings.
A bitmap represented as a string
This is essentially the format of pixels in the BMP format in which each row is aligned to a four-byte boundry and each row contains a series of RGB pixels.
This type is most efficient for programs interacting heavily with BMP files.
