ImageRegion Property

Summary
RasterImage object that is updated with a shallow copy of image that also has a region that contains the removed borders.
Syntax
C#
VB
Objective-C
C++
Java
public RasterImage ImageRegion { get; } 
Public ReadOnly Property ImageRegion As RasterImage 
@property (nonatomic, strong, readonly, nullable) LTRasterImage *imageRegion 
public RasterImage getImageRegion() 
public: 
property RasterImage^ ImageRegion { 
   RasterImage^ get(); 
} 

Property 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

Run the BorderRemoveCommand on an image.

C#
VB
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
using Leadtools.ImageProcessing.Color; 
 
public void ImageRegionPropertyExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Clean.tif")); 
 
   // Prepare the command 
   BorderRemoveCommand command = new BorderRemoveCommand(); 
   command.Border = BorderRemoveBorderFlags.All; 
   command.Flags = BorderRemoveCommandFlags.UseVariance | BorderRemoveCommandFlags.SingleRegion | BorderRemoveCommandFlags.LeadRegion; 
   command.Percent = 20; 
   command.Variance = 3; 
   command.WhiteNoiseLength = 9; 
 
   command.Run(image); 
 
   using (RasterRegion tempRegion = command.ImageRegion.GetRegion(null)) 
   { 
      image.SetRegion(null, tempRegion, RasterRegionCombineMode.Set); 
   } 
 
}

   public const string ImagesDir = @"C:\LEADTOOLS21\Resources\Images";

   command.Run(leadImage) 
 
   Using tempRegion As RasterRegion = command.ImageRegion.GetRegion(Nothing) 
      leadImage.SetRegion(Nothing, tempRegion, RasterRegionCombineMode.Set) 
   End Using
