Rust library for encoding/decoding ASCII Hex Image (.ahi) and ASCII Hex Font (.ahf) files.
ASCII Hex Image (AHI) is a simple text-based format for storing collections of small, 16-color images. It is intended for storing sprites for games or other graphical applications, in a way that makes changes to image files result in (semi-)human-readable VCS diffs.
A typical .ahi file looks like this:
ahi0 w20 h5 n2
0000000000000FFF0000
FFFFFFFFFFFFFF11FF00
F11111111111111111FF
FFFFFFFFFFFFFF11FF00
0000000000000FFF0000
0000FFF0000000000000
00FF11FFFFFFFFFFFFFF
FF11111111111111111F
00FF11FFFFFFFFFFFFFF
0000FFF0000000000000
The top-level crate documentation has more details about the format spec.
ASCII Hex Font (AHF) is a variation on the AHI file format, meant for storing 16-color bitmap fonts as an ASCII text file.
A typical .ahf file looks like this:
ahf0 h6 b5 n2
def w4 s5
1111
1001
1001
1001
1001
1111
'A' w5 s6
01110
10001
11111
10001
10001
00000
'g' w4 s5
0000
0111
1001
0111
0001
0110
