GetDeskewAngle Method
Summary
Gets the angle of the skew of this IOcrPage.
Syntax
int GetDeskewAngle() Function GetDeskewAngle() As Integer int GetDeskewAngle() - (NSInteger)deskewAngle:(NSError **)error public int getDeskewAngle() function Leadtools.Forms.Ocr.IOcrPage.GetDeskewAngle() int GetDeskewAngle(); Return Value
The angle of the skew of this image expressed in tenth of degrees.
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 Recognize. 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.
Use GetPreprocessValues to obtain the accumulative pre-processing values applied to this IOcrPage.
Example
For an example, refer to AutoPreprocess.
