Remarks

If the DeskewOptions property contains DeskewCommandDeskewOptions.ReturnAngleOnly, the activity will update the Angle property without rotating the image.
The calculated rotation is limited to 20 degrees in either direction. This activity is intended for images, such as scanned documents, that are mainly horizontal lines of text. The results are less predictable with other types of images.
This activity includes an option to skip deskewing if the angle is very small.
This activity does not support 12 and 16-bit grayscale and 48 and 64-bit color images. If the image is 12 and 16-bit grayscale and 48 and 64-bit color, the activity will not throw an exception.
This activity does not support signed data images.
This activity does not support 32-bit grayscale images.
