Initializes a new PlasmaCommand with explicit parameters.
Syntax
Parameters
- opacity
- A percentage value that indicates the amount of blending between the plasma color patterns and the original image. Possible values range from 0 to 100. Use 0 when not using an image, and 100 when not using the plasma values.
- size
- Value greater than 0 that represents the plasma size. (The value is divided internally by 100). The value, after it has been divided by 100, represents the size in pixels.
- shift
- The amount of color shift in the plasma color pattern. Valid range for the 16, 48, and 64-bit images is from 0 to 65535 and for 12-bit images from 0 to 4095. Otherwise, it is from 0 to 255. A value of 0 means there is no color shift.
- redFrequency
- Value that indicates which frequencies of red color should be used to create plasma patterns. Valid range for the 16, 48, and 64-bit images is from 0 to 65535 and for 12-bit images from 0 to 4095. Otherwise, it is from 0 to 255. Use 0 to turn off processing for the red frequencies.
- greenFrequency
- Value that indicates which frequencies of green color should be used to create plasma patterns. Valid range for the 16, 48, and 64-bit images is from 0 to 65535 and for 12-bit images from 0 to 4095. Otherwise, it is from 0 to 255. Use 0 to turn off processing for the green frequencies.
- blueFrequency
- Value that indicates which frequencies of blue color should be used to create plasma patterns. Valid range for the 16, 48, and 64-bit images is from 0 to 65535 and for 12-bit images from 0 to 4095. Otherwise, it is from 0 to 255. Use 0 to turn off processing for the blue frequencies.
- flags
- Enumeration that indicates which type of plasma effect to create, and which color pattern to use.
Example
Run the Leadtools.ImageProcessing.SpecialEffects.PlasmaCommand on an image.
