hitTestPoint Method


Performs hit-testing on this AnnContainer at the specified point.


JavaScript Syntax
AnnContainer.prototype.hitTestPoint = function(point) 
TypeScript Syntax
hitTestPoint(point: LeadPointD): AnnObject[]; 



The point to be tested in annotation units.

Return Value

An array of AnnObject intersects with.


HitTestBuffer can be used to make the test point "bigger" to compensate for errors and provide smoother hit-testing. For example, if buffer is 2, a square with a length of 4 units around testPoint will be used to perform the hit-testing.

If more than one object overlaps underneath the test point, the method will return the object on top of the Z-order.
