I hope there is a solution to this, albeit I realize this is a strange approach.
I would like to export co-ordinates from annotations within a rectangle, with the co-ordinates being relative to the said rectangle not the entire slide.
Possible solution: I draw a large rectangle within my slide and crop the image so that only that rectangle remains. The first point of the rectangle should become the new (0,0) co-ordinate. Therefore I can draw new annotations on the cropped image and export those co-ordinates.
I can successfully export co-ordinates but I don’t know how to crop a digital slide, or if a better workaround can be achieved.
