Remarks

  • This command detects the edge pixels by comparing the values of the pixel with surrounding pixels and if the edge value (the difference between the surrounding pixels and the pixel being evaluated) is greater than the Threshold value, the pixel is an edge pixel. The command then multiplies the values for the edge pixels by the brightness factor.
  • This command does not support signed data images.
