LEADTOOLS WinRT (Leadtools.Annotations.Core)
LEAD Technologies, Inc

HitTest Method (AnnRectangleObject)


The Leadtools.LeadPointD to be tested.
The threshold buffer value, in pixels.
Performs hit-testing on this AnnRectangleObject. WinRT support
Syntax
public override bool HitTest( 
   LeadPointD point,
   double hitTestBuffer
)
 function Leadtools.Annotations.Core.AnnRectangleObject.HitTest( 
   point ,
   hitTestBuffer 
)

Parameters

point
The Leadtools.LeadPointD to be tested.
hitTestBuffer
The threshold buffer value, in pixels.

Return Value

A value that represents the hit-test value; or null if the test point is not on top of this AnnObject.
Remarks

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.

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
