Hello,
I am working on conversion of PPT to PDF topic. I am using appose total license with “aspose-slides-v23.3” version.

We have PPT where we have some images. When we convert PPT to PDF then we are getting blurred view of some images.

In attached slide we have added two same images, only difference is that for image1 we have added some shape effect properties. For image2 we have not added any property. But when we convert PPT to PDF we get different result for those images.

I am attaching :

  1. Source PPT where we can see images view is clear.
  2. Target PDF generated where image1 view is blur.

Please help us to understand this issue.
Thanks, Data.zip (303.7 KB)

@dnyandevp,
Thank you for reporting on the issue. I’ve reproduced the same problem with the blurred image.

The result will be better if you use PdfOptions as follows

var pdfOptions = new PdfOptions();
pdfOptions.setSufficientResolution(600);

var presentation = new Presentation("TEST IMAGES.pptx");
presentation.save("output.pdf", SaveFormat.Pdf, pdfOptions);

but some blur effects will remain.
