Where does OcrPageOrientationResult live in the IronOCR API?

OcrPageOrientationResult is a class in the IronOcr namespace, shipped in IronOcr.dll. It derives from System.Object and represents the result of page orientation detection on an OcrInput.

How do you tell how far a page is rotated in C#?

Read the RotationAngle property of an OcrPageOrientationResult for the detected rotation in degrees, use PageNumber to identify the page, and check HighConfidence to decide whether the angle is reliable enough to apply automatically.

Class OcrPageOrientationResult

Represents the result of page orientation detection.

Inheritance

System.Object

OcrPageOrientationResult

Namespace: IronOcr

Assembly: IronOcr.dll

Syntax

public class OcrPageOrientationResult : Object

The rotation a page needs before its text reads correctly arrives in C# as an OcrPageOrientationResult. It reports, per page, how far the content is turned and whether the detection was confident, so a workflow can rotate a sideways or upside-down scan before recognition rather than feeding skewed pages to the engine. It is the orientation-detection counterpart that travels with OrientationConfidence, which carries the underlying confidence values this result summarizes into a single flag.

The members are read straight off the object. PageNumber identifies which page the result describes, RotationAngle gives the detected rotation in degrees that the page should be corrected by, and HighConfidence is a boolean that reports whether the detection was reliable enough to act on automatically. Branch on HighConfidence first: when it is true, apply RotationAngle to straighten the page; when it is false, route the page for review or fall back to a more thorough detection mode rather than trusting an uncertain angle.

The detect page rotation how-to shows orientation detection in a read, and the image orientation correction how-to straightens pages before recognition.
