Braille
Braille dots, 2×4 per cell: eight decisions where ASCII has one.
Controls
- pitch
- Distance between neighbouring dots. A cell is two pitches wide and four high, so this sets everything else
- gap
- Space between cells, in dot pitches. At zero it merges into one lattice and only the name is left of Braille
- size
- Dot diameter against the pitch. At one the dots touch into a solid blob; smaller, the lattice stays visible
- threshold
- The brightness at which a dot is raised
- dither
- Moves the threshold from dot to dot so a gradient survives. At zero it is one honest hard threshold — real relief has no halftones
- contrast
- A number from -1 to 1, 0 by default.
- ink
- A colour, #e8e4dc by default.
- paper
- A colour, #14161a by default.
