Image Export Hangs for Slide with Embedded Excel Sheet on Linux

For the attached sample file I found Presentation.GetThumbnails to hang when running a .NET Core app on Linux with Aspose.Slides 21.8. Hanging means I gave up after 5+ minutes and killed the process. (31.0 KB)

Thank you for the issue description. I have reproduced the problem with the hanging of thumbnail rendering and logged the issue with ID SLIDESNET-42762 in our tracking system. Our development team will investigate this case. You will be notified when the problem is fixed.

Hi @Andrey_Potapov - I wanted to check if you had an update regarding this issue. With version 21.10 I still observed that Presentation.GetThumbnails hangs.

I have requested information from our development team for you. We will reply to you as soon as possible.

The issue investigation will begin next week.

The issues you have found earlier (filed as SLIDESNET-42762) have been fixed in this update.

Are you sure that the issue is resolved? I tested again with Aspose.Slides 21.12 and 22.1 and still saw that GetThumbnails was hanging with an embedded OLE object like in the presentation above.

Please share the following additional information about the environment in which your code was run:

  • Linux distribution
  • .NET Core version

@Andrey_Potapov - Running on Ubuntu 21.04 with .NET Core 3.1.17

Update: After updating System.Drawing.Common package to 5.0.0 the application works.

Thank you for the additional information.
Aspose.Slides for .NET Core does not support System.Drawing.Common 6.0.0 yet. The latest supported version is 5.0.3. We are glad your issue has been resolved.
