CopyImageCommand Class

Summary

Creates a copy of a RasterImage object.

Syntax

Objective-C

C++

Java

public class CopyImageCommand : RasterCommand, IDestDataCommand

Public Class CopyImageCommand 
   Inherits RasterCommand

@interface LTKernelCopyImageCommand : LTRasterCommand

public class CopyImageCommand extends RasterCommand

public ref class CopyImageCommand : public RasterCommand

Remarks

After the command is run, a copy of the current page of the source image will be in the CopyImageCommand.DestinationImage property. This property will hold a copy of the image, so the user is responsible for freeing this image after using it.

This command supports 12- and 16-bit grayscale and 48- and 64-bit color images. Support for 12- and 16-bit grayscale and 48- and 64-bit color images is available only in the Document/Medical Imaging toolkits. This command supports unsigned data images, but not signed ones. This command does not support 32-bit grayscale images. This function can only process entire images. It does not support regions.

Note: All RasterCommands in this assembly modify the underlying properties of the input RasterImage, including but not limited to:

BitsPerPixel
Data
IsMirrored

If you wish to avoid RasterImage property fidelity loss, pass a clone of your RasterImage to all RasterCommands in this assembly.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Kernel; 
 
public void CopyImageCommandExample() 
{ 
   using (RasterCodecs codecs = new RasterCodecs()) 
   { 
      // Load an image 
      using (RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "PerspectiveDeskew.jpg"))) 
      { 
         CopyImageCommand command = new CopyImageCommand(); 
         command.Run(image); 
 
         codecs.Save(command.DestinationImage, Path.Combine(LEAD_VARS.ImagesDir, "ClonedImage.bmp"), RasterImageFormat.Bmp, 24); 
 
         // Free cloned image 
         command.DestinationImage.Dispose(); 
      } 
   } 
} 
 
static class LEAD_VARS

   public const string ImagesDir = @"C:\Users\Public\Documents\LEADTOOLS Images";
