multiple length measurements of straight lines

[Stephan-26]

Dear all,

I have quite a number of images with many straight streaks in there.
All I need is the length of each streak; a streak can easily be regarded as
a line but it does not make sense to measure it as a very streched ellipse.
My plan is to measure the length of all those streaks preferably automated,
that is, not by hand.

Is there a way to do this?

Hi Stephan,

is Feret's diameter what you are looking for?

See the documentation of Set Measurements,

that's a straight tip, thanks a lot.
