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.

Format of Wireless Bitmap Files
Field name Field type Size (in bytes) Purpose
Type uintvar variable Type of the image, and is 0 for monochrome bitmaps.
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.

Notes
    gollark: Yes, privacy-focused stuff often lacks features. But even if someone came up with "Facebook but significantly better somehow", network effects mean adoption would be very slow.
    gollark: Discord isn't ideal, but at least they seem to have a mostly non-data-harvesting business model and somewhat better privacy policy.
    gollark: Pretty much, as long as they are also not exposing data from their friends/contacts to big companies too.
    gollark: That's a different thing, I guess.
    gollark: The network effects thing also doesn't apply to, say, use of other random cloud services. Unless you are also synchronizing your contacts and other data vaguely related to other people to those.
