CopyDataCommand Class

Summary

Copies image data from one image to another.

Syntax

Objective-C

C++/CLI

Java

Python

public class CopyDataCommand : RasterCommand

@interface LTCopyDataCommand : LTRasterCommand

public class CopyDataCommand extends RasterCommand

public ref class CopyDataCommand : public RasterCommand

class CopyDataCommand(RasterCommand):

Remarks

The destination image must accurately identify the copied data. Therefore, the following properties must specify the same values for both the source and destination images:

The CopyDataCommand works by copying the image data from the image passed to the Run method to the image passed in the DestinationImage property.

Example

This example will use the CopyDataCommand to copy the image data from a source image to an existing image

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
 
 
public void CopyDataCommandExample() 
{ 
	RasterCodecs codecs = new RasterCodecs(); 
 
	string srcFileName = Path.Combine(LEAD_VARS.ImagesDir, "Image1.cmp"); 
	string destFileName = Path.Combine(LEAD_VARS.ImagesDir, "CopyDataCommand.bmp"); 
 
	// Load the source image from disk 
	RasterImage srcImage = codecs.Load(srcFileName); 
 
	// Create the destination image with same dimension as the source image 
	RasterImage destImage = new RasterImage( 
	   RasterMemoryFlags.Conventional, 
	   srcImage.Width, 
	   srcImage.Height, 
	   srcImage.BitsPerPixel, 
	   srcImage.Order, 
	   srcImage.ViewPerspective, 
	   srcImage.GetPalette(), 
	   IntPtr.Zero, 
	   0); 
 
	// Copy the image data from the source image to the destination image 
	CopyDataCommand command = new CopyDataCommand(); 
	command.DestinationImage = destImage; 
	command.Run(srcImage); 
 
	// Save it to disk 
	codecs.Save(destImage, destFileName, RasterImageFormat.Bmp, 24); 
 
	// Clean Up 
	srcImage.Dispose(); 
	destImage.Dispose(); 
	codecs.Dispose(); 
}
