Remarks

  • This command will warp the image as a 3D spherical shape around a specific center point. 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.
  • This command does not support 32-bit grayscale images.
