Resizes the image from an existing image, and puts the resized image into a destination image, leaving the original image intact.

Inherits Leadtools.Imageprocessing.RasterCommand

public ref class ResizeCommand : public Leadtools.Imageprocessing.RasterCommand, Leadtools.Imageprocessing.IRasterCommand
The ResizeCommand command works by resizing the image data passed to the Run method into the image passed to the DestinationImage property.
The destination image must be initialized with the correct RasterImage.Width and RasterImage.Height of the new, resized image.
This command does not change the source image passed to the Run method. If you want to resize an image without creating a new version, use the SizeCommand.
For more information, refer to Introduction to Image Processing With LEADTOOLS.
This example will load an image then resize into an existing smaller image
