GetDeskewAngle Method

Summary

Gets the angle of the skew of this IOcrPage.

Syntax

Objective-C

C++

Java

public int GetDeskewAngle()

Function GetDeskewAngle() As Integer

- (NSInteger)deskewAngle:(NSError **)error

public int 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.
