headsort: streaming sort + 2x faster than gnu sort
...This means it has new applications in distributed computing and in some cases makes dc un-necessary. (gnu sort must finish all bins)
Well compatible with gnu sort (not perfect).
other algorthms featured if menu used:
bubble, selection, insertion, shell, distributive counting, straight radix, radix exchange, quick, merge. (some are by character, some by line, some both)
angif fork with transparency layers (proof of concept implementation)
fork of Phil Howards Angif 1.0.0 beta3 (http://freecode.com/projects/angif)
Implemented "layered" (usage of transparency) 24bit color-depth support for gif instead of the original tiled one (mosaic of 255 color gifs). Instead of the divide-and-conquer approach this one uses sorting (bubblesort, sorry) for color frequency and distance grouping.
Build as windows command line tool with MingGW.
Workflow: import truecolor image to GIMP, export 24RAW from GIMP, feeding to rawtogif.exe e.g. "rawtogif.exe 1024 768 sunflower.raw"
output a uncompressed (no LZW compression) GIF, needs to be feed to gifsicle for reasonable size.
