Hi, Aspose team.

Scenario:

There are 2 issues while converting PowerPoint presentation to PDF:

  • Gray artifact lines appear in the PDF that are not present in the original PowerPoint file (page 3 and 4)

  • The edges of circles in the PowerPoint file appear coarse in the PDF (page 2)

Document to replicate - File-with-issue-elements.zip (750.0 KB)

We tested Aspose.Slides.NET 25.6 and Aspose.PDF 25.6

Code to replicate:

var ppt = new Aspose.Slides.Presentation(path);

var pptxPdfOption = new PdfOptions
{
    Compliance = Aspose.Slides.Export.PdfCompliance.Pdf17
};

ppt.Save(output, Aspose.Slides.Export.SaveFormat.Pdf, pptxPdfOption);

Expected behavior:

  • no gray lines on page 3 and 4

  • the edge of circle are smooth in the PDF

For internal reference: CLN-2598.

Thanks.
