This command supports detecting deskew and orientation angles.

ref class DetectDeskewOrientationCommand : RasterCommand
This command contains special algorithms for detecting skewed checks.
This command does not support signed data images.
The calculated rotation is limited to 20 degrees in either direction. This command 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 command does not support 12- and 16-bit grayscale or 48- and 64-bit color images. If the image is 12- and 16-bit grayscale or 48- and 64-bit color, the function will not return an error.
This command does not support 32-bit grayscale images.
Runs the DetectDeskewOrientationCommand
on an image.
