LEADTOOLS JavaScript (Leadtools.Annotations.Core)

HitTest Method (AnnPointerObject)

Show in webframe

Performs hit-testing on this AnnPointerObject.

Syntax

JavaScript

 function Leadtools.Annotations.Core.AnnPointerObject.hitTest( 
   point ,
   hitTestBuffer 
)

Parameters

Parameter	Type	Description
point	LeadPointD	The Leadtools.LeadPointD to be tested.
hitTestBuffer	double	Threshold buffer value, in pixels.

Return Value

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

Remarks

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.
