hey there,

can anyone recommend a tool for cutting a big tileset file into many little individual image files?

thanks
a.

ImageMagick provides a commandline tool that can programmatically crop out regions from files. For example, to make a 32x32 crop with upper-left corner at (128, 32) you'd do:

convert -crop 32x32+128+32 tileset.png outputtile.png

If the tiles are all the same size, you could easily cut them out from the tilesheet using two nested for loops.

perfect. does it do nice scaling as well?

convert -crop 64x64+256+128 -resize 50% tilesheet.png outputtile.png

More generally, there's a list of commandline options here, and there's plenty of tutorials for common operations, readily-findable on Google.

FastStone Photo Resizer handles batches and does all kinds of stuff.
Also GlueSprites is a tiny GUI tile sheet chopper/reassembler.
