A command line tool to split up sprite-sheets into their constituent images.
I couldn't get any of those online sprite-sheet decomposers to work so here's a quick NodeJS take on the problem.
How to use it:
install it:
npm i -g @tomgp/decompose-sprites
run it:
node index.js -i ./test-images/badges-50-sprite.png -w 50 -h 50 -o ./test-images/output
./test-images/badges-50-sprite.png 50 50
Options
-V, --version output the version number
-i, --image [path] input image [path]
-w, --width [pixels] sprite width [pixels]
-h, --height [pixels] sprite height [pixels]
-o, --outdir [path] output directory [path]
-h, --help output usage information
