vbf (IN DEVELOPMENT)

a visual bitmap font format. you can edit a .vbf font with a text editor like its ASCII art (recommend you use a monospaced font with a 2:1 ratio)

uppercase alpha is very
similar to uppercase A
so lets use the same 
for both             +------------------+

examples

glyphs are defined in floating boxes drawn with + - |. everything not in a box is ignored. pixels are drawn two characters wide: or XX

each glyph is mapped to one or more unicode sequences (a series of U+XXXX codepoints) separated by commas. whitespace in the header box is ignored.

converting to/from psf

install the two conversion tools:

pip install vbftools

convert to/from .psf:

psf_to_vbf < font.psf > font.vbf
vbf_to_psf < font.vbf > font.psf

(note: psf requires that all glyphs are the same size)

load a psf font: setfont font.psf
show the current font: showconsolefont
compress a font: gzip font.psf
decompress a font: gunzip font.psf.gz
find fonts: man setfont
