Wireless Application Protocol Bitmap Format (shortened to Wireless Bitmap and with file extension .wbmp) is a monochrome graphics file format optimized for mobile computing devices. WBMP images are monochrome (black & white) so that the image size is kept to a minimum. A black pixel is denoted by 0 and a white pixel is denoted by 1. For colored images, WAP supports the Portable Network Graphics format. The bitmap where b = black and w = white Row1 - bwb Row2 - wbw Row3 - bwb becomes Octet 1: 00000000 (WBMP type) Octet 2: 00000000 (Fixed header) Octet 3: 00000011 (Width) = 3 Octet 4: 00000011 (Height) = 3 Octet 5-7: 3 bits for data then Padding (8-3=5) Octet 5: 010 00000 (Row 1) Octet 6: 101 00000 (Row 2) Octet 7: 010 00000 (Row 3) less
