Dividing segmented line

[chyekeong]

Hi,

I am tracing images of blood vessels with segmented lines, and would like to measure the diameter of the vessels at even intervals along the vessel. Is there a way of dividing a segmented line into equal parts of a set length?

Thanks and regards,
Chye Keong

Hi Chye Keong,

what about Edit>Selection>Straighten?
Then it would be easier to write a macro for measuring the diameter  
of the straightened vessel.

I wrote a plugin for modeling collaterals and making arterial diameter
measurements along vascular segments in the mouse.  Perhaps it would
be of use to you.
