is within ... polygon shape?

[Lynch, Jonathan]

Good stuff...

I was not the original asker for this - I just chimed in because it
peaked my interest.

Cheers,

Because on my end I tried:

  if firstWithinSecond("mypoly1","mypoly2") *and* ...

instead of:

  if firstWithinSecond("mypoly1","mypoly2") *or*

Replacing "and" with "or" makes your routine work as expected (I should
have
known something was up on my end being the math guru that you are).

So Jonathan, there you are: two routines that allow you to test
intersection
with images or polygons.
