Detecting wether a point is inside or outside of a raphael.js shape

Question

I have a raphael.js shape which I am plotting circle\'s on top of. I only want a circle to appear if the circle does not go off the boundary of the shape it is being plotted

Answer 1

This looks very similar to "Hit-testing SVG shapes?".

You'll just need to call getIntersectionList() on the circle's position, and see if it returns the big gray shape.
