public class AddCommand : Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

'Declaration
 
Public Class AddCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage
 
Dim instance As AddCommand

public sealed class AddCommand : Leadtools.ImageProcessing.IRasterCommand

@interface LTAddCommand : LTRasterCommand

public class AddCommand extends RasterCommand

function Leadtools.ImageProcessing.Color.AddCommand()

public ref class AddCommand : public Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

This operation can be used to add several images of the same view to improve the lightness or brightness of the image. It can also eliminate the random noise contained in these images by doing an average of all images.
This command performs operations between data byte-by-byte. An image can be any color resolution. This command will allocate and store the resulting image in the DestinationImage property. The image resulting from this operation is internally copied from the first image in the list, before performing the adding operation. The operations are performed based on the smallest width and height of the input images.
All images must be either signed or unsigned.
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 toolkits.
This command does not support 32-bit grayscale images.

For more information, refer to Changing Brightness and Contrast.
