Issues with PowerPoint Presentation when Saving as PDF or HTML in C#

Aspose.Slides Product Family

Hello,

we noticed an issue with a presenation of a customer. I attached you an example with reduced content which still shows the issue:
When saving the presentation as PDF or HTML the elements and texts become blurry on some slides. If you export the presentation to pdf via power point itself, you get a good result.

Additionally, when saving the presentation as HTML5 an exception is raised

An unhandled exception of type ‘System.InvalidOperationException’ occurred in Aspose.Slides.dll
Additional information: SolidFillColor is unavailable for FillType=Picture

Code:

var lic = new License();
lic.SetLicense(@"S:\Aspose.Total.Net.lic");

var presentation = new Presentation(@"S:\tmp\in.pptx");

presentation.Save(@"S:\tmp\out.pdf", SaveFormat.Pdf);
presentation.Save(@"S:\tmp\html_aspose\out.html", SaveFormat.Html);
presentation.Save(@"S:\tmp\html5_aspose\out.html", SaveFormat.Html5);

Thanks for your help,

@Serraniel,
Thank you for reporting the issue.

I’ve reproduced the problem with the blurred content when converting the presentation to PDF and HTML and added a ticket with ID SLIDESNET-43544 to our issue-tracking system. We apologize for any inconvenience. Our development team will investigate the case. You will be notified when a new release of Aspose.Slides with a fix is published.

It would be great if you could share the following additional information:

  • OS version on which the code was executed
  • .NET target platform in your app

We will then also test a solution in an environment similar to yours.
