(Leadtools.Annotations.Core)

HitTest Method (AnnObject)

Show in webframe





The Leadtools.LeadPointD to be tested.
Threshold buffer value, in container units.
Performs hit-testing on this AnnObject.
Syntax
public virtual bool HitTest( 
   LeadPointD point,
   double hitTestBuffer
)
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

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.
