# Experimental lossless image compression
8bit RGB images, alpha channel ignored, input must be PNG.
Compile:
```
make
```
Usage:
```
./choh infile.png outfile.hoh speed
```
Where ``speed`` is a number in the range ``0`` to ``10`` (inclusive). increasingly slower and better compression. (Higher numbers are also accepted, but usually don't help much)
Decoding:
```
./dhoh infile.hoh outfile.png
```
