LEADTOOLS OCR (Leadtools.Forms.Ocr assembly)

GetDeskewAngle Method

Show in webframe







Gets the angle of the skew of this IOcrPage.
Syntax
int GetDeskewAngle()
'Declaration
 
Function GetDeskewAngle() As Integer
'Usage
 
Dim instance As IOcrPage
Dim value As Integer
 
value = instance.GetDeskewAngle()
int GetDeskewAngle()
- (int)getDeskewAngle:(NSError**)outError;
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 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.

Example
For an example, refer to AutoPreprocess.
