Can the GIMP break apart a icon sheet?
Now here is the sheet in question.
[Image: muchbetter.png]

Now I've already manually broken apart this image into 256 icons, but that was considerably time consuming. (I also did this with a second sheet with just as many icons.) Now I heard that the GIMP could do this automatically for me. If that is true, then I would like to also now the following.

1: Will png transparency be preserved?
2: Will I be forced to use a base 10 naming convention? Or can I name the rows and columns?
(As in scrollAquamarineRed.png, scrollRedSliver.png, scrollGreenBurgundy etc, etc.)
3: Will I get a copyable text list of all the files generated?

Also no, I didn't know name every scroll, I used a hexadecimal naming convention.

RE: Can the GIMP break apart a icon sheet?
Sorry for taking so long to respond, but thank you for directing me to ImageMagick. It does exactly what I need it do. I've done some playing around and I think I've got all the commands I need to work this.

For decimal output
convert INPUT.png -crop 32x32! OUTPUT%03d.png

For Hexadecimal output
convert INPUT.png -crop 32x32! OUTPUT%02x.png

For changing Directory in MS DOS Prompt
Type cd

For change drive in MS DOS Prompt
Type Drive letter then a colon (E:)

For getting a copyable list.
Type DIR when in output directory, right click and select mark, highlight desired data, hit enter, copy data into notepad.
