Some more thoughts: * Other implementations: There is other people who have done such a thing. the PIL knows how to read and write PNG, but only 8 bit. The same holds for matplotlib.

Our VIGRA imaging library can read and save PNGs with 8/16 bit data, as well as several kinds of TIFF files (including float data). We are currently trying to re-model our python bindings (which have not yet been officially released) using NumPy containers for the images. Unfortunately, we seem to get a performance penalty by the common convention that the order of the indices is x,y, e.g. colorImage[x,y] == [r,g,b].
