How to Fix Image Orientation for Reading

using IronOcr;

// The IronTesseract class provides advanced OCR capabilities, allowing
// you to recognize text from images.
var ocrTesseract = new IronTesseract();

// The OcrInput class is used to define input images for OCR processing.
// Here, we're specifying an image file for input.
using var ocrInput = new OcrInput("paragraph_skewed.png");

// Logically rotate the image by 180 degrees using the Rotate method.
// This prepares the image for OCR by ensuring it's in the correct orientation.
ocrInput.Rotate(180);

// Save the rotated image to a new file. To correctly save the modified image,
// we use the SaveAsImages method which accepts a directory name and saves 
// the images within that directory.
ocrInput.SaveAsImages("rotated_images_directory");

// Perform OCR on the rotated image.
// The Read method processes the image and returns the results.
var result = ocrTesseract.Read(ocrInput);

// Output the recognized text to the console.
Console.WriteLine(result.Text);

// Note: The Read method reads the OcrInput and recognizes the text,
// which is stored in the OcrResult object and then outputted.
