@bjenkin,
Thank you for contacting support.

Please check your results using the latest version of Aspose.Slides if it is possible. If the issue persists, please share the following data and information:

  • presentation file (you can zip the file and upload it here)
  • code example that reproduces the error
  • OS version where the code was executed
  • JDK version in your app
  • Aspose.Slides version you used

As this is a production issue and lots of files are processed we cannot know for sure the actual file that was used. This happens often. this would imply and uncaught exception somewhere in the apose code base.

@bjenkin,
Thank you for the additional information. I’ve added a ticket with ID SLIDESJAVA-38847 to our issue tracking system. Our development team will review your code and the error dump. We will inform you of any progress.

@bjenkin,
Our developers have reviewed your code and the error dump. Because the exception related to JDK/libfreetype version, please try to use the latest JDK and/or update libfreetype.
