necessarily inside the graphic's containing rectangle?

Ray,
Have you tried the within() function? It works the way you describe for images,
but I'm not sure about
If it doesn't work the same with graphics you could cheat and snapshot,
overlay, check, delete the snapshot.

Unfortunately my feeble attempt with:
on mouseDown
grab me

This works for graphics objects as well, as long as their opaque is true.

if the grc is set to opaque (or selected) it works fine,

I like the idea of trying to get within() to work.
But if that does not work, try computing.
Consider a horizontal line through the point. Find the points where it crosses
the line segments of the sides. (Take care of the special case of a line
segment being on your horizontal line.) Count

Of course you might also want to take a look at the animationEngine sourcecode,
which has a function for that. ;-)

What's wrong with intersect(grc pointThing, grc polyThing, pixels)?
Assuming opaque polygon, of course.

It seems opaque has come up several times.
I wonder if that can be set temporarily inside lock screen and get the right
results for polygons that are not opaque.

What a cool idea! I also wonder if blending will work? I'm going to go play.
Thanks!

Well:
I made a stack with a regular polygon shape (7 sides)
filled with a very 'fetching' green,
and a field called INN,
and put this script into the graphic:
on mouseWithin
put the mouseColor into fld INN
end mouseWithin
and . . .
when the mouse was WITHIN the coloured polygon I got
Is the opaque pixelx functionality fixed for the current version (with
intersect)? It was broken in 6.0 community.
