hitTest Method

Summary

Performs hit-testing on this AnnObject.

Syntax
TypeScript
JavaScript
AnnObject.prototype.hitTest = function( 
   point, 
   hitTestBuffer 
) 
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 the buffer is 2, a square with a length of 4 units around the test point will be used to perform the hit-testing. Derived objects can override this method to fine-tune the return value.
