Image Quality Issue when Converting PowerPoint Presentation to PDF in VB.NET

Hi!

Please find attached a solution that contains an input.pptx file and a small console application that renders a PDF. The image in the PDF has much lower quality than the image in the PPTX (compare with zoom factor 200 % or more). Is there a bug in Aspose Slides or what are we doing wrong?

Thanks and BR,
Bernd

Hi - Did this quality issue only happen for powerpoint to PDF conversion?

And should it be sufficient to only update this single DLL to fix this issue?

@chris23,
Yes, we recommend using the latest version of Aspose.Slides for .NET.
