HitTestRect Method

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

Syntax

WinRT C#
WinRT JavaScript

public AnnObject[] HitTestRect( 
   LeadRectD rect
)

 function Leadtools.Annotations.Core.AnnContainer.HitTestRect( 
   rect 
)

Parameters

rect: The rectangle to be tested in annotation units.

Return Value

An array of AnnObjects that rect 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.

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
