3 | # File by mwedel@scruz.net to deal with splitting png's. |
4 | # Takes any number of files on the command line, but all the split images |
5 | # are dumped in the current directory. |
6 | # does preserve alpha channel. Tested on skree images. |

8 | # Modification by PeterM |
9 | # Notes: I don't really know how this script was supposed to work |
10 | # I use it like this: |
11 | # > mkdir out (makes an output directory so I don't clobber my input) |
12 | # > split-png-linux.pl file.111.png |
13 | # |
14 | # The results end up in the directory "out" |
