Fixed header | byte | 1 | Reserved. Always 0. |
Width | uintvar | variable | Width of the image in pixels. |
Height | uintvar | variable | Height of the image in pixels. |
Data | byte array | variable | Data bytes arranged in rows – one bit per pixel. A black pixel is denoted by 0 and a white pixel is denoted by 1. Where the row length is not divisible by 8, the row is 0-padded to the byte boundary. |
