[Fwd: RE: Determining max width]

[morphmet]

Hello all,

I have a question for which I suspect there is a fairly straightforward
answer:

I have images of cross sections of human ribs (for the uninitiated, they
kind of look like fat commas) for which I want to determine maximum width
(orthogonal to the max. height). For our rib "comma", max width would be
at the fat part.  Does tpsDig2 (or any other utility) do any of the
following?:


   1. Determine max width by itself, perhaps with help from a reference 2.
Allow superimposition of a grid to aid in determining the widest point
without having to eyeball it
   3. Create a reference line between two points that can then be moved
allowing you to block in the points like calipers might

Thanks!
