Wireless Bitmap (WBMP)

A Wireless Bitmap (WBMP) is a graphic image format for use when sending Web content to handheld wireless devices. The format is defined as part of the Wireless Application Protocol (WAP), Wireless Application Environment (WAE) Specification. If you are creating Web content that is directed to handheld phones or personal digital assistants (PDA) that have Web access, you use the Wireless Markup Language (WML) to encode the page and its text. An image can be included in the form of a WBMP file -- initially, supported only in black-and-white -- that you can convert from a Graphics Interchange Format (GUI), Tag Image File Format (TIFF), or other graphic formats.

The initial WAP WAE specification supports only WBMP type 0, which is an compression image in monochrome. Later, as the bandwidth for wireless transmission increases, richer images will be supported.
