Well, one can also write a SNG [1] file, I suppose (I never tried it).

[1] http://www.catb.org/~esr/sng/
"SNG (Scriptable Network Graphics) is a minilanguage designed specifically to represent 
the entire contents of a PNG (Portable Network Graphics) file in an editable form. Thus, 
SNGs representing elaborate graphics images and ancillary chunk data can be readily 
generated or modified using only text tools."
