as PNG and image data is downloaded as compressed format, similar to using Base
Maps but without the tilling, the PNG is then overlaid on the raster image.
Does this makes sense?, would it be feasible for the a future development? The
idea is you zoom and pan as normal for a non tiled map.<o:p></o:p></span></font></span></p>
