ChangeSaturationCommand Class

Summary
Increases or decreases the saturation of colors in an image.
Syntax
C#
Objective-C
C++/CLI
Java
Python
public class ChangeSaturationCommand : RasterCommand 
@interface LTChangeSaturationCommand : LTRasterCommand 
public class ChangeSaturationCommand 
    extends RasterCommand 
public ref class ChangeSaturationCommand : public RasterCommand   
class ChangeSaturationCommand(RasterCommand): 
Remarks
  • Negative values decrease the saturation of colors. Positive values increase the saturation. The saturation level is increased or decreased by a percentage of its present saturation level. For example, an increase of 20 percent of the current saturation level "L" will raise the new saturation level "L1" to a value L + 0.20 * L. Likewise, increasing the saturation level 100 percent doubles the saturation level ( L1 = L + 1.0 * L). Decreasing the saturation level 100 percent will set the new saturation level to 0. This process is carried out for every pixel.
  • 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 supports unsigned data images, but not signed ones.
  • This command does not support 32-bit grayscale images.

Example

Run the ChangeSaturationCommand on an image and increase its color saturation.

C#
Java
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
 
public void ChangeSaturationCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "ImageProcessingDemo\\Image1.jpg")); 
 
   // Prepare the command 
   ChangeSaturationCommand command = new ChangeSaturationCommand(); 
   //Increase the color saturation by 25 percent  of the possible range. 
   command.Change = 250; 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24);
