hitTest Method (AnnObject)
Summary
Performs hit-testing on this AnnObject.
Syntax
JavaScript Syntax
AnnObject.prototype.hitTest = function(point, hitTestBuffer)TypeScript Syntax
hitTest(point: LeadPointD, hitTestBuffer: number): boolean;Parameters
point
The LeadPointD to be tested.
hitTestBuffer
Threshold buffer value, in container units.
Return Value
true if the test point intersects with the object; otherwise, false.
Remarks
hitTestBuffer is 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 the test point will be used to perform the hit-testing.
By default, an annotation object will return true if hit-testing was satisfied. Derived objects can override this method to fine tune the return value.
