Class OrientationDetectionMode

Define how IronOcr detect orientation angle of pages in an OcrInput

Inheritance

System.Object

OrientationDetectionMode

Namespace: IronOcr

Assembly: IronOcr.dll

Syntax

public sealed class OrientationDetectionMode : Enum

Choose 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.

Fields

Balanced

Determine orientation angle with balance speed and accuracy, suitable to use for default or production task

Declaration

public const OrientationDetectionMode Balanced

Field Value
