PNG is a lossless format.

Anyway, you will have different resulting sizes for the same image and 
the same compression level between Qt and GTK+, because the saved image 
metadata is not exactly the same.

The solution is what I implemented in the IDE: using 'pngquant' once the 
image is saved to get the smallest possible png file.
