// Register PDF support (call once at startup)
DocumentParserFactoryExtensions.AddPdfSupport();

// Text extraction
var parser = DocumentParserFactory.GetParser(".pdf");
var text = parser!.ExtractText(File.ReadAllBytes("document.pdf"));

// Page image rendering
var mediaParser = (IMediaDocumentParser)parser;
var images = mediaParser.ExtractImages(File.ReadAllBytes("document.pdf"), dpi: 150);
foreach (var img in images)
    File.WriteAllBytes($"{img.Label}.png", img.Data);
