Name OS/2 Bitmap
Version 1.0
Other names  
Identifiers PUID:  x-fmt/25
Classification Image (Raster)
Description PUID deprecated. Please see fmt/115 for information on OS/2 Bitmap 1.0 and Windows Bitmap 2.0. The only difference between Windows bitmap 2.0 and OS/2 bitmap 1.0 is the data type of the width and height fields of the bitmap header – for Windows 2.0 bitmaps they are signed short integers, for OS/2 1.0 bitmaps they are unsigned shorts. For positive numbers the representation is the same. Consequently, the file formats cannot be distinguished with a file signature test. The PUID for OS/2 Bitmap 1.0 has therefore been deprecated.
