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.
