Converting PDF to PNG is very slow

Aspose.PDF Product Family

Hi,
I’m converting a PDF to a PNG via this piece of code :

 Aspose.Pdf.Document docNoAnnotation = new Aspose.Pdf.Document(ActivePDF);
      List<Annotation> annotations = docNoAnnotation.Pages.First().Annotations.Cast<Annotation>().ToList();
      annotations.ForEach(x => docNoAnnotation.Pages.First().Annotations.Remove(x));
      //Aanmaken van een PNG van de pdf
      Aspose.Pdf.Devices.PngDevice dev = new Aspose.Pdf.Devices.PngDevice();
      //dev.CoordinateType = Aspose.Pdf.PageCoordinateType.MediaBox;
      dev.RenderingOptions.OptimizeDimensions = true;
      

      dev.Process(docNoAnnotation.Pages[1], $@"{System.IO.Path.GetTempPath()}\{project.id}.png");

Before converting, I remove all the annotations and then I process the document. This processing takes about 1 minute to complete.

Is this normal behavior ?

TIA,
Mark
