Image Support

WBMP Images

The 4625SW Web browser supports rendering of Wireless Bitmap (WBMP) images. WBMP is a

graphic format optimized for mobile computing devices. At present WBMP supports only a

simple picture format that is restricted to bi-level (black and white pixel) images.

A WBMP image is identified using a TypeField value, which describes encoding information

such as pixel and palette organization, compression, and animation. The TypeField value also

determines image characteristics according to WAP documentation. An Image Type Identifier

represents Type Field values. Currently, there is only one type of WBMP specified. The Image

Type Identifier label for this is 0.

This image type has the following characteristics:

● No compression

● One bit color (white=1, black=0)

● One bit deep (monochrome)

The 4625SW Web browser does not support graphic animation.

WBMP is part of the Wireless Application Protocol, Wireless Application Environment

Specification Version 1.1. The WBMP specification is available at:

http://www.wapforum.org/docs/technical1.1/

Many utilities are available as shareware to convert other graphical file formats to the WBMP

format.
