DetectOrientationByText Method of the ImageProcessingTools Object
This method detects the image orientation using the text lines.
Visual Basic .NET
Function DetectOrientationByText( _ Image As Image, _ Language As Language, _ ) As RotationTypeEnum
HRESULT DetectOrientationByText( IImage* Image, ILanguage* Language, RotationTypeEnum* Result );
- [in] Refers to the Image object which is to be processed.
- [in] Refers to the Language object which specifies the language of the text on the image.
- [out, retval] Returns a RotationTypeEnum constant.
This method has no specific return values. It returns the standard return values of ABBYY FlexiCapture SDK functions.
This method returns the image orientation, that is, the angle by which the image was rotated from normal. To detect the angle needed to turn the image the right way up, use the DetectRequiredRotation method. The results returned by the two methods will be the opposite of each other.
