Ohohoo and a happy new year.

For something to do I have waded through the QT4 and GTK Picture 
classes. It appears to me that adding a ToString() method for QT would 
be a simple ("hahaha" said the so-called C expert) matter as the 
underlying buffer into which the file is loaded does not appear to be 
destroyed while the Picture exists and it is essentially a byte array. 
Now for GTK, guess what?! The initial buffer is released after it is 
loaded and converted to a picture! So it is not going to be so simple to 
create a way to develop a simple ToString().

I accept that this does not advance towards a solution but it may 
relieve some of your angst about the implied "Why isn't?

cheers
