Step 3: Create AsposeOCR Instance

Instantiate the AsposeOCR class to utilize its OCR functionalities.

AsposeOCR api = new AsposeOCR();

Step 4: Recognize Page

Use the RecognizePage method to extract text from the specified image.

try {

    System.out.println("Result: " + result);
} catch (IOException e) {
    e.printStackTrace();
}
