HitTest Method (AnnEllipseObject)

public override bool HitTest( 
   LeadPointD point,
   double hitTestBuffer
)

'Declaration
 

Public Overrides Function HitTest( _
   ByVal point As LeadPointD, _
   ByVal hitTestBuffer As Double _
) As Boolean

public override bool HitTest( 
   LeadPointD point,
   double hitTestBuffer
)

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

 function Leadtools.Annotations.Core.AnnEllipseObject.HitTest( 
   point ,
   hitTestBuffer 
)

Parameters

point

The Leadtools.LeadPointD to be tested.

hitTestBuffer

Threshold buffer value, in pixels.

Return Value

The point should be in physical coordinates.

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 pixels around testPoint 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.
