Looks like part of the problem is the CP’s mode allows you to place points outside the image boundary.
I assumed since it allowed it, you must be doing some fancy extrapolation and still provided some location information for the image. Or what it does it make it crash… one of these things takes less coding than the other
Suggest two features…
one - don’t let the tagging happen outside the image boundary if you aren’t prepared to cope with that.
two - if you encounter loaded/saved points beyond the specified image edges, either discard or disable that point with a warning.
(colour ! triangle again on the image in the control point list?)
I’ll parse the control point file and see how it goes when I clip for boundary manually…
but hey - using position information from points outside the image would be a great addition
Thank you
