HitTest Method

Summary

Performs hit-testing on this AnnPolylineObject.

Syntax

C++/CLI

Java

Python

public override bool HitTest( 
   LeadPointD point, 
   double hitTestBuffer 
)

@Override public boolean hitTest( 
   LeadPointD point, 
   double hitTestBuffer 
)

public:  
   virtual bool HitTest( 
      LeadPointD^ point, 
      double hitTestBuffer 
   ) override

def HitTest(self,point,hitTestBuffer):

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.
