- This command retrieves the number of black objects on a white background in a binary image. The behavior of this command can be further modified by using an Event Handler that handles the ObjectCounterCommandEventArgs.
- 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 there isn't a region selected, the whole image will be processed.
- This command does not support signed data images.
