Syntax

C#
VB
Java
Objective-C
WinRT C#
C++
public class AddNoiseCommand : RasterCommand 
@interface LTAddNoiseCommand : LTRasterCommand 
public class AddNoiseCommand extends RasterCommand 
function Leadtools.ImageProcessing.Effects.AddNoiseCommand() 

Remarks
  • 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.
