Remarks

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

    And you were to call ZigZagCommand 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:
  • If the image has a region, the effect will be applied on the region only.
  • This command supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64 bit color images is available only in the Document/Medical toolkits.
  • This command does not support signed data images.
  • This command does not support 32-bit grayscale images.
