sng

SNG (Scriptable Network Graphics) is a mini-language designed specifically to represent the entire contents of a PNG in an editable form. Thus, SNGs representing elaborate graphics images and ancillary chunk data can be readily generated or modified using only text tools. SNG is implemented by a compiler/decompiler called sng that losslessly translates between SNG and PNG.
