Usage

``` USAGE: pngeq [OPTIONS]

FLAGS: -h, --help Prints help information -V, --version Prints version information

OPTIONS: -d, --dither Ditherer to use [values: none, ordered, fs, fs-checkered] -O, --opt Palette optimization [values: 0, s1, s2, s3, c1, c2, c3]

ARGS: target color count for output input truecolor png

output 8bit png

K-Means optimization levels: none ('0'), optimize for smoothness ('s1' - 's3'), optimize for colors ('c1' - 'c3'). Defaults depend on NUM_COLORS: > 128 color: 's1', > 64 colors: 's2', >= 32 colors: 'c2', < 32 colors: 'c3' Available ditherers: 'none', 'ordered', 'fs', 'fs-checkered' ```
