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




RasterImage object that is updated with a shallow copy of image that also has a region that contains the removed borders.

Syntax

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

Return Value

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

Example

Visual BasicCopy Code
ImageProcessing.Core.BorderRemoveCommand.ImageRegion
   Public Sub ImageRegionPropertyExample()
      RasterCodecs.Startup()
      Dim codecs As New RasterCodecs()
      codecs.ThrowExceptionsOnInvalidImages = True

      Dim leadImage As RasterImage = codecs.Load("C:\Program Files\LEAD Technologies\LEADTOOLS 15\Images\Clean.tif")

      ' Prepare the command
      Dim command As BorderRemoveCommand = New BorderRemoveCommand
      command.Border = BorderRemoveBorderFlags.All
      command.Flags = BorderRemoveCommandFlags.UseVariance Or BorderRemoveCommandFlags.SingleRegion Or BorderRemoveCommandFlags.LeadRegion
      command.Percent = 20
      command.Variance = 3
      command.WhiteNoiseLength = 9

      command.Run(leadImage)
      leadImage.AddGdiPlusRegionToRegion(Nothing, command.ImageRegion.RegionToGdiPlusRegion(Nothing), RasterRegionCombineMode.Set)

      RasterCodecs.Shutdown()
   End Sub
C#Copy Code

         command.WhiteNoiseLength = 9; 
 
         command.Run(image); 
         image.AddGdiPlusRegionToRegion(null, command.ImageRegion.RegionToGdiPlusRegion(null), RasterRegionCombineMode.Set);  
 
         RasterCodecs.Shutdown(); 
      }
