BMP is a device independent, two dimensional raster graphics file format introduced with OS/2 v1.0 and later incorporated into Microsoft Windows where it replaced the now forgotten DDP format. The name is simply a shortening of "Bitmap" and not an acronym.
Two specialised versions of the format exist in the form of the Pointer and ICO raster graphic array files.
