How to Get Read Confidence

using IronOcr;

// This code performs Optical Character Recognition (OCR) using the IronOcr library.
// It reads text from an image file and retrieves the recognized text's confidence level.

// Instantiate IronTesseract, the OCR engine
var ocrTesseract = new IronTesseract();

// Load an image from a file to use as input for OCR
// Using 'using var' ensures proper disposal of resources, as OcrInput implements IDisposable
using var imageInput = new OcrInput("sample.tiff");

// Perform OCR on the image input
OcrResult ocrResult = ocrTesseract.Read(imageInput);

// Retrieve the confidence level of the OCR process
double confidence = ocrResult.Confidence;

// Output the result and confidence to console for verification and debugging purposes
Console.WriteLine("OCR Result: " + ocrResult.Text);
Console.WriteLine("Confidence Level: " + confidence);
