HitTest Method (AnnPolylineObject)

public override bool HitTest( 
   LeadPointD point,
   double hitTestBuffer
)

 function Leadtools.Annotations.Core.AnnPolylineObject.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.

The 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.

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
