HitTest Method

Summary

Performs hit-testing on this AnnPolylineObject.

Syntax
C#
VB
C++
Java
public override bool HitTest( 
   LeadPointD point, 
   double hitTestBuffer 
) 
Public Overrides Function HitTest( _ 
   ByVal point As LeadPointD, _ 
   ByVal hitTestBuffer As Double _ 
) As Boolean 
@Override public boolean hitTest( 
   LeadPointD point, 
   double hitTestBuffer 
) 
public:  
   virtual bool HitTest( 
      LeadPointD^ point, 
      double hitTestBuffer 
   ) override 

point

The Leadtools.LeadPointD to be tested.

hitTestBuffer

Threshold buffer value, in pixels.

Return Value

true if the test point intersects with the object; otherwise, false.

Remarks

The point should be in physical coordinates.

The 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 pixels 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.
