HitTestPoint Method

Summary

Performs hit-testing on this AnnContainer at the specified point.

Syntax
C#
VB
Java
Objective-C
C++
public AnnObject[] HitTestPoint( 
   LeadPointD point 
) 
Public Function HitTestPoint( _ 
   ByVal point As LeadPointD _ 
) As AnnObject() 
-(LTAnnObjectCollection*)hitTestPoint:(LeadPointD)point; 
public AnnObject[] hitTestPoint(LeadPointD point) 
public:  
   array<AnnObject^>^ HitTestPoint( 
      LeadPointD^ point 
   ) 

Parameters

point
The point to be tested in annotation units (1/720 of an inch).

Return Value

An array of AnnObjects that point intersects with.

Remarks

HitTestBuffer can be 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 testPoint will be used to perform the hit-testing.

If more than one object overlaps underneath the test point, the method will return the object on top of the Z-order.
