is within ... polygon shape?

[Lynch, Jonathan]

This command:

Put the points of image "myImage1" into field "feedback"

Causes an error - it says this object does not have this property. I am
misunderstanding something aren't I?

It works reliably with images as long as the transparent regions of the
image are 100% transparent.  Try it.

Routines for polygons should work reliably as well.

(Although Jim's routine seems to work only for intersecting edges, and
not
when a smaller polygon falls *completely* within a larger polygon -- any
tweak available Jim?)
