We are to renew the license in Jan-2024. Will the fix be released before that? Also, will the new license have any impact on the .NET Total libraries?

Hi Team,

We tried 23.10, 23.11 & 23.11.1 and we see the text missing in the output TIFF. Could you please help?

Code snippet for reference:

public MemoryStream ConvertPDFPagetoTIFF(Aspose.Pdf.Document pdfDocument)
{
try
{
pdfDocument.Flatten();
MemoryStream outputStream = new MemoryStream();
/// Create Resolution object
Aspose.Pdf.Devices.Resolution resolution = new Aspose.Pdf.Devices.Resolution(Convert.ToInt32(this.PluginParameters[“Resolution”]));

      /// Create TiffSettings object
      Aspose.Pdf.Devices.TiffSettings tiffSettings = new Aspose.Pdf.Devices.TiffSettings
      {
          Depth = Aspose.Pdf.Devices.ColorDepth.Format8bpp,
          SkipBlankPages = false
      };
      tiffSettings.CoordinateType = Aspose.Pdf.PageCoordinateType.CropBox;
      /// Set TIFF Compression
    
          tiffSettings.Compression = Aspose.Pdf.Devices.CompressionType.LZW;
      
      /// Create TIFF device
      TiffDevice tiffDevice = new TiffDevice(resolution, tiffSettings);
      tiffDevice.FormPresentationMode = Aspose.Pdf.Devices.FormPresentationMode.Editor;
      tiffDevice.RenderingOptions = new RenderingOptions()
      {
          SystemFontsNativeRendering = true,
          UseFontHinting = true,
          ConvertFontsToUnicodeTTF = true
      };
      /// Convert PDF Stream to TIFF Stream
      tiffDevice.Process(pdfDocument, outputStream);
      /// Return the TIFF pages as MemoryStream object
      return outputStream;
  }
  catch (Exception ex)
  {
      throw ex;
  }

@Manikandan.Murugan

Can you please share the sample document with us so that we can test the scenario in our environment and address it accordingly.

39

Hi @asad.ali ,

I have shared the file on the Private Chat that we used earlier to share the files.

@Manikandan.Murugan

While testing the case with your file and the latest version of the API, we faced below exception in our environment:

System.NullReferenceException: 'Object reference not set to an instance of an object.'

Would you kindly confirm if you are using 23.11 version? OR can you please try using the latest version and share the feedback with us?
