Code:
char on1_xpm[]={47, 42, 32, 88, 80, 77, 32, 42, 47, 10, 115, 116, 97, 116, 105, 99, 32, 99, 104, 97, 114, 32, 42, 32, 119, 9
7,
116, 99, 104, 111, 110, 95, 120, 112, 109, 91, 93, 32, 61, 32, 123, 10, 34, 50, 48, 32, 50, 48, 32, 53, 52, 32,
49, 34, 44, 10, 34, 32, 9, 99, 32, 78, 111, 110, 101, 34, 44, 10, 34, 46, 9, 99, 32, 35, 68, 48, 50, 67,
49, 48, 34, 44, 10, 34, 43, 9, 99, 32, 35, 67, 66, 50, 49, 48, 67, 34, 44, 10, 34, 64, 9, 99, 32, 35,
67, 54, 49, 55, //etc
and unlike other image types all the values are characters, so I imagine this shouldn't be too hard to sort out.
