    Command-line tool to check ADFs (Amiga Disk Files) for errors and viruses. A binary is included for Windows users; Linux users are advised to compile the application themselves. Might also compile under plain DOS; but BE WARNED! When you scan files already renamed by the TOSEC standard, consider that file names may become insanely long in no time. --UPDATE OCTOBER 2014-- This project is currently suspended! I can't currently find the time to fix/update anything with this program and hence it must be considered 'on hold' at the moment. Sorry for the inconvenience.

    angif layered

    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 (bubble sort, 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.
