WBM, WBMP: Wireless Bitmap files



The Wireless Application Forum introduced a wireless image standard known as the Wireless BitMap (WBM), a format that is optimized for use by handheld devices. WBMs use a TypeField value, which describes encoding information like pixel and palette organization, animation and compression and also determines image characteristics. Such values are represented by an ImageType Identifier. The Image Type Identifier label for supported WBM files is 0, currently the only type that a WAP device supports. Type 0 WBM files are uncompressed monochrome (1 bit per pixel) files.
