See Also  Example
Leadtools.ImageProcessing.Core Namespace > DotRemoveCommand Class : ImageRegion Property



This property is updated with a shallow copy of the image that also has a region that contains the removed dots.

Syntax

Visual Basic (Declaration) 
Public ReadOnly Property ImageRegion As RasterImage
Visual Basic (Usage)Copy Code
Dim instance As DotRemoveCommand
Dim value As RasterImage
 
value = instance.ImageRegion
C# 
public RasterImage ImageRegion {get;}
C++/CLI 
public:
property RasterImage ImageRegion {
   RasterImage get();
}

Return Value

A shallow copy of the image that also has a region that contains the removed dots.

Example

Run the DotRemoveCommand on an image.

Remarks

If DotRemoveCommandFlags.SingleRegion| DotRemoveCommandFlags.LeadRegion has been set in Flags, then when DotRemoveCommand returns, this property is updated with a shallow copy of the image that also has a region that contains the removed dots. So set Flags to (DotRemoveCommandFlags.SingleRegion| DotRemoveCommandFlags.LeadRegion). It is the programmer's responsibility to dispose of the region when it is no longer needed.

Requirements

Target Platforms: Microsoft .NET Framework 2.0, Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family
