AgingCommand Class

Summary

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 Imaging and above toolkits.

Syntax

C++/CLI

Python

public class AgingCommand : RasterCommand

public ref class AgingCommand : public RasterCommand

class AgingCommand(RasterCommand):

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-bit and 16-bit grayscale and 48-bit and 64-bit color images. Support for 12-bit and 16-bit grayscale and 48-bit 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.

Example

Run the AgingCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
 
public void AgingCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE1.CMP")); 
 
   // Prepare the command 
   AgingCommand command = new AgingCommand(); 
   command.HorizontalScratchCount = 10; 
   command.VerticalScratchCount = 2; 
   command.MaximumScratchLength = 50; 
   command.DustDensity = 2; 
   command.PitsDensity = 5; 
   command.MaximumPitSize = 6; 
   command.ScratchColor = new RasterColor(255, 255, 0); 
   command.DustColor = new RasterColor(0, 0, 0); 
   command.PitsColor = new RasterColor(0, 0, 255); 
   command.Flags = AgingCommandFlags.AddVerticalScratch | AgingCommandFlags.AddPits | AgingCommandFlags.ScratchInverse | AgingCommandFlags.PitsColor; 
 
   //Apply aging effect. 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24);
