ZoomWaveCommand Class

Distorts the image with a wave zoomed from the specified center. This command is available in the Imaging Pro and above toolkits.
public class ZoomWaveCommand : RasterCommand 
Public Class ZoomWaveCommand  
   Inherits RasterCommand 
public ref class ZoomWaveCommand : public RasterCommand   
  • The command applies a sinusoidal wave zoomed from the specified center. The center point must be defined inside the image, or inside the region, if the image has a region.
  • 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-bit and 64-bit color images is available only in the Document/Medical toolkits.
  • This command does not support signed data images.
