The aesthetical sense or nonsense of the converter is a question of personal view. But what is with the technical question? I have often talked about the possibility of saving lots of memory space, what could especially be useful when dealing with larger pictures or e.g. videos, but how are the facts?
A Deep Picture isn't just splitted into high and low resoluted disconnected parts, the borders are smooth. The pixels grow steadily from the center to the pictures corners. One can choose between linear and exponential growth (This one is exponential). For both of these options, the pixel-growth can be adjusted very precisely. Is there a point, in which the resolution suddenly changes? - No, everything is smooth! In the example below you can see the net structure, that is because I took a snapshot of the SVG-file.
