Module sixel 

Sixel graphics: DCS p1 ; p2 q <data> ST, as DEC’s VT340 drew them and SyncTERM (CTerm) and xterm do today. Decoded here to an Image, which the screen places at the cursor (see crate::screen::Screen::place_image).

Each data character ?..~ is six pixels in a column (bit 0 at the top) in the current color; !n repeats the next one, #n picks a color and #n;2;r;g;b (or ;1;h;l;s) defines one, $ returns to the start of the six-pixel band and - starts the next band. "pan;pad;w;h sets the pixels’ shape and the picture’s size.

Structs

Image

A picture: 0xFFRRGGBB pixels, 0 where nothing was drawn.

Functions

decode

Decode a sixel string: params are the DCS parameters before q, data what follows it. Unset pixels are background (opaque) unless p2 is 1, when they stay see-through.

solid

An opaque pixel.
