Chafa 1.4.0

on GitHub

This release adds major features to both libchafa and the chafa
command-line tool.

• Added sixel graphics support. Chafa will automatically produce sixels
  if the connected terminal supports it. It can also be forced using the
  new -f or --format flag. This is a new implementation written from the
  ground up to maximize throughput.

• Added the --glyph-file option, which loads glyph-symbol mappings from
  any file format supported by FreeType (TTF, PCF, etc). This allows for
  custom font support and improved symbol selection.

• Added the --speed option specifying animation speed. It accepts a
  unitless multiplier, a specific number of frames per second, or max
  for maximum throughput.

• There are now two ways to assign colors to symbol cells. Formerly,
  this was done based on the average color of the covered area. The new
  default is to use the median color, which produces sharper edges,
  but is slightly more prone to high-frequency noise. The new option
  --color-extractor selects the method to employ.

• When displaying multiple files, the default delay between files has
  been changed from three seconds to zero. Animations will still play
  through once. This can be overridden on the chafa command line with -d
  or --duration.

• Minor tweaks to built-in symbols.

• Performance improvements:

  • Halved pixel storage requirements from 64 bits to 32 bits, resulting
    in significant memory savings.
  • Now builds with -ffast-math, yielding a big speedup for DIN99d.
