Description : convert images to text abusing Unicode
This tool takes an image and converts it to a dot matrix text
representation using the Unicode range U+2800..28FF. This allows
to hold an image at a resolution of 2×4 pixels per character used.
Certain fonts show those glyphs as a matrix of empty and filled circles,
which is readable only at a very high DPI and/or font size.
Alas, most actual Braille readers provide only a single row, thus making
these images hard to see by real blind people.
Also included is braillegraph, a simple graphing tool that makes
It has been proposed, but rejected, to incorporate this into catimg (ITP
#852878) -- its upstream prefers KISS. That tool produces images at a far
less resolution (2×2 or 4×4 times less) but in color. Color looks nice, but
limits catimg's use to catting to a terminal, less -R or ansi2html, while
black&white brailleimg can be used anywhere Unicode text can go.
