Hi...sorry if something similar has already been posted but that didn't help me.
I am doing 2D image analysis on photos, and in addition to something like ImageJ which allows the placement of points and the measuring of angles and lengths, I need something that can draw midpoint, tangent and parallel lines based on coordinate locations in the image. I have tried all the standard geometry programs ubuntu has to offer but none of them allow opening an image to edit on. Any ideas?
Thanks!
