Leadtools.ImageProcessing.SpecialEffects Namespace : 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.

Syntax

Visual Basic (Declaration)  
Public Class AgingCommand 
   Inherits RasterCommand
   Implements IRasterCommand 
Visual Basic (Usage) Copy Code
Dim instance As AgingCommand
C#  
public class AgingCommand : RasterCommand, IRasterCommand 
C++/CLI  
public ref class AgingCommand : public RasterCommand, IRasterCommand 

Example

Run the AgingCommand on an image.

Visual Basic Copy Code
Public Sub AgingCommandExample()
   RasterCodecs.Startup()
   Dim codecs As New RasterCodecs()
   codecs.ThrowExceptionsOnInvalidImages = True

   Dim leadImage As RasterImage = codecs.Load(LeadtoolsExamples.Common.ImagesPath.Path + "Master.jpg")

   ' Prepare the command
   Dim command As AgingCommand = New AgingCommand()

   command.PitsColor = New RasterColor(0, 0, 255)
   command.Flags = AgingCommandFlags.AddVerticalScratch Or AgingCommandFlags.AddPits Or AgingCommandFlags.ScratchInverse Or AgingCommandFlags.PitsColor

   'Apply aging effect.
   command.Run(leadImage)
   codecs.Save(leadImage, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24)

   RasterCodecs.Shutdown()

   //Apply aging effect. 
   command.Run(image); 
   codecs.Save(image, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24); 
 
   RasterCodecs.Shutdown(); 
}

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.
