Class OrientationDetectionMode
Define how IronOcr detect orientation angle of pages in an OcrInput
Inheritance
Namespace: IronOcr
Assembly: IronOcr.dll
Syntax
public sealed class OrientationDetectionMode : EnumChoose OrientationDetectionMode to set how hard IronOCR works to detect the rotation angle of pages in an OcrInput. Balanced trades speed against accuracy and is the right pick for default or production reads. Fast favors speed for draft or bulk processing, while Detailed and ExtremeDetailed spend more time for higher accuracy, with ExtremeDetailed even recovering skewed text. The Detailed and ExtremeDetailed modes require the IronOcr.Extensions.AdvancedScan package and are unavailable on Windows x86 and Mac ARM.
input.OrientationDetectionMode = OrientationDetectionMode.Balanced;The detect page rotation how-to shows orientation detection in context.
