Of course, when you use a polygon.
I've been meaning to put together a means of using graphics/polygons as
masks for some time now, and your email served as the inspiration to do so.
Execute the following in your message box (requires Rev 3 or later):
(Watch line wrap -- should be all one line.)
Two methods are shown in the demo stack, both of which rely on a combination
of ink effects and a group. While not quite as straightforward as
SuperCard, you can achieve the same effect. Plus, using the same
techniques, you can do even better by using an image as a mask, which allows
you to create soft edges around the "holes" of the mask. See the spotlight
demo available on my site:
go url "http://www.tactilemedia.com/site_files/downloads/spotlight.rev"
Of course an image is not a polygon, but you get the idea.
Hope this is useful.
