I have images which have line like features, and I need to measure length of each line segment. I am
doing this manually, i.e., measuring the length of each line segment, looking up the length on the
toolbar, and typing it in Kaleidagraph. I cannot use the automatic measure because my TEM images
are not very high-contrast images, and thresholding would give a very high amount of error.

My problem: Is there a way to retain a line selection? When I go to the next feature, the last one
disappears. this creates confusion as I have to keep a close track of which line segments I have
measured. If they can be marked, the job (which is really tedious) will become a little easier.

Thanks
