PlasmaCommand Class

Summary

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

Syntax

C++

public class PlasmaCommand : RasterCommand

  
Public Class PlasmaCommand  
   Inherits RasterCommand

public ref class PlasmaCommand : public RasterCommand

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 CustomColor 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-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 method does not support signed data images.
This command does not support 32-bit grayscale images.

Example

Run the PlasmaCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
public void PlasmaCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\Image2.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, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}

   public const string ImagesDir = @"C:\LEADTOOLS21\Resources\Images";
