Remarks

  • Negative sharpness values decrease the sharpness of the image. Specify -1000 for minimum sharpness. Positive sharpness values increase the sharpness. Specify +1000 for maximum sharpness.
  • This operation 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 operation does not support 32-bit grayscale images.
