It’s a rewrite of Dinnerbone’s utility to convert Minecraft texture packs to the 1.5 format.
java -jar unstitcher.jar [-h | <input>.zip [<output>.zip]]
Calling it without parameters invokes the GUI, else the logging takes place in the command line and no window is shown.
- can be called from the command line for batch-conversions
- supports bigger texture packs due to more memory-efficient code
- supports converting animations (except lava and water as of yet)
