The snapshot tool in 1.7 has been vastly improved. It is now possible to produce larger snapshots quicker and more accurately matching the viewport setup. The bug with the clipping region inconsistency between viewport and snapshot has been fixed as have the grid markers bug. On large images the markers would run-out.
You can also add your own logo to the snapshot (in position of Pointools motif shown in image)and an image title. See image below!

This image was produced straight out of Pointools View Pro - nothing has been added.
These features will be available in the next 1.7 release due in late August.
