Remarks

  • The command will blur and zoom the image around the specified 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. It returns the error code ERROR_GRAY32_UNSUPPORTED if a 32-bit grayscale image is passed to this method.
