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"
