%description
pngquant is a command-line utility and a library for lossy
compression of PNG images.

The conversion reduces file sizes by converting images to 1/2/4/8-bit
paletted PNG format with alpha channel (often 60-80%% smaller than
24/32-bit PNG files). Generated images are compatible with all modern
web browsers, and have better fallback in IE6 than 24-bit PNGs.

- Update to version 2.11.2:
  + added support for `-o -`.
  + windows/JNI build fixes.
- Changes from version 2.8:
  + libimagequant is a separate project.
  + --strip option to disable copying of PNG metadata.
- Changes from version 2.7:
  + improved dithering of saturated and semitransparent colors.
  + fixed order of log output when using openmp.
  + improved quality sanity check in --skip-if-larger option.
  + disabled palette post-processing on colors from --map option to
    preserve them exactly.
- Changes from version 2.6:
  + when source image has no color profile information, the output
    won't have either.
- Changes from version 2.5:
  + replaced color search algorithm with vantage point tree, which
    is much faster and more reliable.
  + deprecated IE6 workaround.
  + warn when compiled without color profile support.
  + Rust API for libimagequant.
- Changes from version 2.4:
  + fixed remapping of bright colors when dithering.
- BuildRequire libimagequant-devel: the library lives in a separate
  project since version 2.8.
