LEAD Technologies, Inc

HitTest Method (AnnObject)


The Leadtools.LeadPointD to be tested.
Threshold buffer value, in container units.
Performs hit-testing on this AnnObject. WinRT support
Syntax
public virtual bool 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.

Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
