Remarks

  • As an example, suppose you call the PlasmaCommandBitmapEffect method, using an Opacity value of 0, which means that no image is to be used, and you use the following settings:
    ParametersValue
    Shift0
    Opacity0
    Size1000
    FlagsRandom1 | 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 PlasmaCommandBitmapEffect. 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 command does not support signed data images.
