Remarks

  • As an example, if you use the following image:

    And you were to call ZigZagCommandBitmapEffect using the following settings:
    ParameterValue
    Amplitude47
    Attenuation92
    Frequency13
    Phase-162
    CenterPoint(192, 82)
    FillColorBlack
    FlagsColor | RadialWave

    The following figure results:

    As another settings, if you use the same settings except you use the PondRippleWave flag, the following figure results:
  • This command does not support signed data images.
