Step 4: Using Parser to Extract Text

Now, create an instance of Parser class with the configured settings.

using (Parser parser = new Parser("YourSampleFile.docx", settings))
{
    // Configure TextOptions for OCR usage
    TextOptions options = new TextOptions(false, true);
    // Extract text using OCR
    using (TextReader reader = parser.GetText(options))
    {
        // Display extracted text or a 'not supported' message
        Console.WriteLine(reader == null ? "Text extraction isn't supported" : reader.ReadToEnd());
