Remarks

  • This command smooths the text in scanned text documents. The behavior of this command can be modified by using an Event Handler that handles the SmoothCommandEventArgs. This command works only on 1-bit black and white images.
  • This command works only on 1-bit black and white images.
  • If a region is selected, only the selected region will be changed by this command. If no region is selected, the whole image will be processed.
  • This command does not support signed data images.
  • This command does not support 32-bit grayscale images.
