ZigZagCommand Class


Radially distorts the image by creating waves that twist the image around a specified center. This command is available in the Imaging Pro and above toolkits.


WinRT C#
public class ZigZagCommand : RasterCommand 
function Leadtools.ImageProcessing.SpecialEffects.ZigZagCommand() 

  • As an example, if you use the following image: And you were to call ZigZagCommand using the following settings:
Parameter Value
Amplitude 47
Attenuation 92
Frequency 13
Phase -162
CenterPoint (192, 82)
FillColor Black
Flags Color | 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-bit and 16-bit grayscale and 48-bit and 64-bit color images. Support for 12-bit 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.
