HitTest Method (AnnObject)

public virtual bool HitTest( 
   LeadPointD point,
   double hitTestBuffer
)

'Declaration
 

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

public virtual bool HitTest( 
   LeadPointD point,
   double hitTestBuffer
)

-(BOOL) hitTest:(LeadPointD)pt
         buffer:(double)buffer;
            

public boolean hitTest(LeadPointD point, double hitTestBuffer)
            

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

Parameters

point

The Leadtools.LeadPointD to be tested.

hitTestBuffer

Threshold buffer value, in container units.

Return Value

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.
