Where does OcrLicensePlateResult live in the IronOCR API?

OcrLicensePlateResult is a class in the IronOcr namespace, shipped in IronOcr.dll. It derives from System.Object and implements IOcrResult, and IronTesseract.ReadLicensePlate returns it.

How do you read a license plate in C#?

Call ReadLicensePlate on an IronTesseract to get an OcrLicensePlateResult, then read its Text for the plate characters and Confidence for the certainty score. The Licenseplate property gives the rectangle where the plate was found.

Class OcrLicensePlateResult

Syntax

public class OcrLicensePlateResult : Object

OcrLicensePlateResult is what a license-plate read hands back, the small result object that carries just the plate text and where it sat in the image. IronTesseract.ReadLicensePlate returns one, so a parking, tolling, or access-control workflow gets the recognized characters without walking a full document model. It is the focused counterpart to OcrResult, which exposes the entire page structure, where this type answers one question: what does the plate say, and how sure is the engine.

The result is read straight off the returned object. Text holds the recognized plate characters and Confidence reports the engine's certainty as a score, so a low value can route a frame for review or a retry. Licenseplate is the Rectangle that locates the detected plate within the source image, useful for drawing an overlay or cropping the region for a second pass. Read Confidence before trusting Text, and use Licenseplate when the location matters as much as the characters.

The read license plate how-to walks through a full read, and the license plate example shows the result fields in code.
