public enum class OcrAutoPreprocessPageCommand : public System.Enum, System.IComparable, System.IConvertible, System.IFormattable

Value	Member	Description
0x00000000	Deskew	Automatic deskewing. If the image is skewed, the IOcrPage.AutoPreprocess method will try to deskew it
0x00000001	Rotate	Automatic rotation. If the image is rotated (its view perspective is anything other than top-left), the IOcrPage.AutoPreprocess method will auto orient it to top-left. This command is especially useful if the image upside-down.
0x00000002	Invert	Automatic inversion. If the image is black and white and is inverted (contains white on black data), the IOcrPage.AutoPreprocess method will automatically convert the image data to be black on white
0x00000003	All	Run all the commands (Deskew, Rotate, Invert)

The OCR engine can perform a series of image pre-processing steps in order to enhance the quality of the image before starting its recognition.

Perform these image pre-processing steps by calling the IOcrPage.AutoPreprocess method. Call this method prior to calling IOcrPage.Recognize or IOcrPage.RecognizeText.

For an example, refer to IOcrPage.AutoPreprocess.
