OS/2 bitmap family
From Just Solve the File Format Problem
IBM OS/2 BMP (also known as Presentation Manager Bitmap or PM Bitmap) is a family of raster graphics formats used on OS/2. It is closely related to Windows BMP.
The term OS/2 BMP can refer just to the "bitmap" formats (files with a signature of "BM"), or to the family of formats that also includes specialized icon and pointer formats.
There are two major versions of the bitmap format: OS/2 BMP 1.0, and OS/2 BMP 2.0. For details, refer to BMP.
For details about the icon format, see OS/2 Icon.
For details about the pointer format, see OS/2 Pointer.
