Hi,

I am trying to add/convert my pdf report to pptx using Aspose.Slides.Net library.
But if my report contains a charts, the presentation is not being created correctly.
When I open the PowerPoint file I see error message

I tried to repair the presentation file, but the charts are not in report anymore and it shows some blank slides

Here is my code

var licenseSlides = new Aspose.Slides.License();
licenseSlides.SetLicense("Aspose.Slides.NET.lic");
var fileName = "test";
fileName = "C:\\Download\\pptx\\" + fileName;
var pdfBytes = File.ReadAllBytes(fileName + ".pdf");
using (Aspose.Slides.Presentation pres = new Aspose.Slides.Presentation())
using (Stream stream = new MemoryStream(pdfBytes))
{
      pres.SlideSize.Orientation = Aspose.Slides.SlideOrientation.Landscape;
      pres.Slides.AddFromPdf(stream);
      if (pres.Slides.Count > 1)
      {
           pres.Slides.RemoveAt(0);
      }
      pres.Save(fileName + ".pptx", Aspose.Slides.Export.SaveFormat.Pptx);
 }

Thank you for the additional information. I was unable to generate the PPTX file, the PDF import hangs on my end. I’ve added a ticket with ID SLIDESNET-43341 to our issue tracking system. We apologize for any inconvenience. Our development team will investigate the case. You will be notified when the issue is resolved.

@skhojoyan,
Our developers investigated the case. Even if the PDF file is visualized properly in PDF readers, the document is broken. The PDF file is 96 kB, but if you open it in Adobe Acrobat and then save it, it will only be 80 kB (many empty objects will be deleted). Could you please clarify how was this PDF file created?

Hi Andrey,
We used iTextSharp.text.pdf.PdfWriter to create PDF file.
Thanks
Sergey

@skhojoyan,
With Aspose.Slides 22.12, I get an ArgumentException error while importing the Sergey_test_23012023_183500.PDF file to a new presentation and an AccessViolationException error while importing the Sergey_test_23012023_183841.PDF document. Could you please confirm that you encountered the same errors?
