As I learned about a year ago (Sept 2004) on this very mailing list:
$ convert foo.png foo.txt
will give you something that looks like:
$ head foo.txt
# ImageMagick pixel enumeration: 72,77,255,RGB
0,0: (254,254,254) #FEFEFE
1,0: (254,254,254) #FEFEFE
2,0: (254,254,254) #FEFEFE
3,0: (254,254,254) #FEFEFE
4,0: (254,254,254) #FEFEFE
5,0: (254,254,254) #FEFEFE
6,0: (254,254,254) #FEFEFE
7,0: (254,254,254) #FEFEFE
8,0: (254,254,254) #FEFEFE
You ought to be able to hack that into whatever format you like pretty
easily.
