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



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

Syntax

Visual Basic (Declaration) 
Public ReadOnly Property ImageRegion As RasterImage
Visual Basic (Usage)Copy Code
Dim instance As InvertedTextCommand
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 inverted text.

Example

Run the InvertedTextCommand on an image.

Remarks

If InvertedTextCommandFlags.SingleRegion| InvertedTextCommandFlags.LeadRegion has been set in the Flags property, then when InvertedTextCommand returns, this property is updated with a shallow copy of the image that also has a region that contains the removed inverted text. So set the InvertedTextCommandFlags.SingleRegion| InvertedTextCommandFlags.LeadRegion flags. 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
