کار با متن در PDF از طریق Python

    // Open document
    Document pdfDocument = new Document(dataDir + "input.pdf");
    // Get particular page
    Page pdfPage = (Page)pdfDocument.Pages[1];
    // Create text fragment
    TextFragment textFragment = new TextFragment("main text");
    textFragment.Position = new Position(100, 600);
    // Set text properties
    textFragment.TextState.FontSize = 12;
    textFragment.TextState.Font = FontRepository.FindFont("TimesNewRoman");
    textFragment.TextState.BackgroundColor = Aspose.Pdf.Color.FromRgb(System.Drawing.Color.LightGray);
    textFragment.TextState.ForegroundColor = Aspose.Pdf.Color.FromRgb(System.Drawing.Color.Red);
    // Create TextBuilder object
    TextBuilder textBuilder = new TextBuilder(pdfPage);
    // Append the text fragment to the PDF page
    textBuilder.AppendText(textFragment);
    dataDir = dataDir + "AddText_out.pdf";
    // Save resulting PDF document.
    pdfDocument.Save(dataDir);
