AgingCommand Class

Adds effects that simulate random color changes, scratches, dust and pits, making an image look like it was made from an old film. This command is available in the Raster Pro and above toolkits.

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

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

'Usage
 
Dim instance As AgingCommand

public sealed class AgingCommand : Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.SpecialEffects.AgingCommand()

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

Remarks

The width of the scratches is 1 pixel. The length of the scratches is random (between 2 and MaximumScratchLength).
The size of the dust particles is 1 pixel (1x1).
The size and shape of pits is selected at random. The pit shapes are random and will be between 1x1 and MaximumPitSize x MaximumPitSize.
The command will also make random changes to the pixel's intensities.
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 signed data images.
This command does not support 32-bit grayscale images.
