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#
VB
WinRT C#
C++
public class PlasmaCommand : RasterCommand 
function Leadtools.ImageProcessing.SpecialEffects.PlasmaCommand() 

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.

C#
VB
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); 
 
}
