just a quick thought following from an earlier comment. As an aid to
getting pixel precision on a larger area than could be displayed in one go
at a sufficient resolution.
If the mouse wheel is configured like googleEarth zoom, could this provide
a way to pinpoint with pixel accuracy each corner of the rectangle without
the need for a loupe?
Scroll zoom , select rectangle vertex 1, zoom out, find second part in
image, zoom in, click second defining vertex.
Currently the zoom is disabled while the mouse button is down.
I'll let Peter suggest the best way implement this. Whether by allowing
mouse scroll events while left button is depressed , or by some other
Currently I dont see a way to select a rectangle larger than the visible
area without compromising precision.
