Syntax

Objective-C

C++/CLI

Java

Python

public class SizeCommand : RasterCommand

@interface LTSizeCommand : LTRasterCommand

public class SizeCommand extends RasterCommand

public ref class SizeCommand : public RasterCommand

class SizeCommand(RasterCommand):

Remarks

This command resizes the image passed to the Run method. If you want to keep the original-size image and create a new resized version, use ResizeCommand.

Example

This example will convert an image to a thumbnail size before saving it to disk.

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
 
 
public void SizeCommandExample() 
{ 
	RasterCodecs codecs = new RasterCodecs(); 
 
	string srcFileName = Path.Combine(LEAD_VARS.ImagesDir, "Image1.cmp"); 
	string destFileName = Path.Combine(LEAD_VARS.ImagesDir, "SizeCommand.bmp"); 
 
	// Load the source image from disk 
	RasterImage image = codecs.Load(srcFileName); 
	SizeCommand command = new SizeCommand(); 
	command.Width = 128; 
	command.Height = 128; 
	command.Flags = RasterSizeFlags.Resample; 
	command.Run(image); 
 
	// Save the image back to disk 
	codecs.Save(image, destFileName, RasterImageFormat.Bmp, 8); 
 
	// Clean Up 
	image.Dispose(); 
	codecs.Dispose();
