ResizeCommand Constructor(RasterImage,RasterSizeFlags)

Summary

Initializes a new instance of the ResizeCommand class with explicit parameters.

Syntax

Objective-C

C++/CLI

Java

Python

public ResizeCommand( 
   RasterImage destinationImage, 
   RasterSizeFlags flags 
)

- (instancetype)initWithDestinationImage:(LTRasterImage *)dstImage  
                                   flags:(LTRasterSizeFlags)flags

public ResizeCommand( 
   RasterImage destinationImage,  
   RasterSizeFlags flags 
)

public: 
ResizeCommand(  
   RasterImage^ destinationImage, 
   RasterSizeFlags flags 
)

__init__(self,destinationImage,flags) # Overloaded constructor

Parameters

destinationImage
The destination image for the resize.

flags
Flags that determine resizing options.

Remarks

The ResizeCommand command works by resizing the image data passed to the Run method into the image passed to destinationImage.

The destination image must be initialized with the correct RasterImage.Width and RasterImage.Height of the new, resized image.

Example

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
 
 
public void ResizeCommandExample() 
{ 
	RasterCodecs codecs = new RasterCodecs(); 
 
	string srcFileName = Path.Combine(LEAD_VARS.ImagesDir, "Image1.cmp"); 
	string destFileName = Path.Combine(LEAD_VARS.ImagesDir, "ResizeCommand.bmp"); 
 
	// Load the source image from disk 
	RasterImage srcImage = codecs.Load(srcFileName); 
 
	// Create the destination image 
	RasterImage destImage = new RasterImage( 
	   RasterMemoryFlags.Conventional, 
	   100, 
	   100, 
	   srcImage.BitsPerPixel, 
	   srcImage.Order, 
	   srcImage.ViewPerspective, 
	   srcImage.GetPalette(), 
	   IntPtr.Zero, 
	   0); 
 
	// Resize the source image into the destination image 
	ResizeCommand command = new ResizeCommand(); 
	command.DestinationImage = destImage; 
	command.Flags = RasterSizeFlags.Bicubic; 
	command.Run(srcImage); 
 
	// Save it to disk 
	codecs.Save(destImage, destFileName, RasterImageFormat.Bmp, 24); 
 
	// Clean Up 
	srcImage.Dispose(); 
	destImage.Dispose(); 
	codecs.Dispose(); 
}
