We’ve got an issue with Aspose Slides on Azure.
When deploying a very simple Web app to Azure and converting a PPTX that contains EMF pictures (like charts) to PDF, these EMF files will not always show up in the converted PDF.
The same thing does work fine when running the application locally, but as soon as we deploy it to Azure, it stops showing the converted EMF pictures in the PDF.
We’re using Aspose.Slides for .NET version 18.9.0, which currently is the latest version.
If I look through your Release notes I see several fixes that might be related:
SLIDESNET-35700 PPT Charts not showing in PDF conversion with Azure Websites
SLIDESNET-38204 - EMF images are not properly rendered in generated pdf
I’ve tried setting the SaveMetafilesAsPng property on Aspose.Slides.Export.PdfOptions to true and false, both options do not help though. I’ve even tried looping through the available presentation.Images collection and converting them to JPG by some c# function and using image.ReplaceImage to update them. This does not work either.
