- 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 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.
