Return Value
The angle of the skew of this image in degrees.Example
Remarks
If the page is not skewed, this method will return 0
Use AutoPreprocess with OcrAutoPreprocessPageCommand.Deskew to automatically deskew the page image prior to calling IOcrPage.Recognize or RecognizeText. This could enhance the quality of the image before starting its recognition.
If the image is skewed, GetDeskewAngle will return the angle needed to deskew the image, if you call AutoPreprocess on the page, all subsequent calls to GetDeskewAngle will return 0 since the image is no longer skewed. Hence, you must use GetDeskewAngle before calling AutoPreprocess.
