PlasmaCommand Class
See Also  Members   Example 
Leadtools.ImageProcessing.SpecialEffects Namespace : PlasmaCommand Class



Applies color patterns that blend into each other like plasma. This command is available in the Raster Pro and above toolkits.

Syntax

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

Example

Run the PlasmaCommand on an image.

Visual Basic Copy Code
Public Sub PlasmaCommandExample()
   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 New PlasmaCommand

   ' Draw crossed plasma colors of size 10 over the current image, use Rgb1 predefined
   ' color pattern without any shifting, and blend the effect into the current image
   ' with opacity of 80%
   command.Flags = PlasmaCommandFlags.Rgb1 Or PlasmaCommandFlags.Cross
   command.Opacity = 80
   command.Size = 1000
   command.Shift = 0
   command.Run(leadImage)
   codecs.Save(leadImage, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24)

   RasterCodecs.Shutdown()
End Sub
C# Copy Code
public void PlasmaCommandExample() 
{ 
   // Load an image 
   RasterCodecs.Startup(); 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(LeadtoolsExamples.Common.ImagesPath.Path + "Master.jpg"); 
 
   // Prepare the command 
   PlasmaCommand command = new PlasmaCommand(); 
 
   // Draw crossed plasma colors of size 10 over the current image, use Rgb1 predefined 
   // color pattern without any shifting, and blend the effect into the current image 
   // with opacity of 80% 
   command.Flags = PlasmaCommandFlags.Rgb1 | PlasmaCommandFlags.Cross; 
   command.Opacity = 80; 
   command.Size = 1000; 
   command.Shift = 0; 
   command.Run(image); 
   codecs.Save(image, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24); 
 
   RasterCodecs.Shutdown(); 
}

Remarks

  • As an example, suppose you call the PlasmaCommand method, using an Opacity value of 0, which means that no image is to be used, and you use the following settings:
    Parameters Value
    Shift 0
    Opacity 0
    Size 1000
    Flags Random1 | Rgb1

    The following figure results:

  • The Opacity value will always be considered to be 0, unless specified otherwise by a value between (and including) 0 to 100.
  • Use the RedFrequency, GreenFrequency, and BlueFrequency to create a custom color pattern. To use them, pass the CustomeColor flag to PlasmaCommand. Otherwise, their values will be ignored.
  • The Hue value is a predefined color pattern that is based on the HLS color space. It creates plasma patterns by changing hue values.
  • The Rgb1 value is a predefined color pattern that is based on the RGB color space. Different combinations of red, green and blue frequencies produce different results.
  • Like the Rgb1 value, the Rgb2 value is based on the RGB color space, but uses a different combination of red, green and blue frequencies.
  • The color palette used for Shift is a continuous cylindrical color palette. In the following figures, one shows where on the palette a value of 0 lies, and the other one shows where on the palette the maximum value lies:
  • This method 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 method does not support signed data images.
  • This command does not support 32-bit grayscale images.
