Remarks

  • 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- 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.
