HitTest Method

Summary

Performs hit-testing on this AnnObject.

Syntax
C#
VB
Java
Objective-C
C++
public virtual bool HitTest( 
   LeadPointD point, 
   double hitTestBuffer 
) 
Public Overridable Function HitTest( _ 
   ByVal point As LeadPointD, _ 
   ByVal hitTestBuffer As Double _ 
) As Boolean 
-(BOOL) hitTest:(LeadPointD)pt 
         buffer:(double)buffer; 
public boolean hitTest(LeadPointD point, double hitTestBuffer) 
public:  
   virtual bool HitTest( 
      LeadPointD^ point, 
      double hitTestBuffer 
   ) 

Parameters

point
The Leadtools.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.
