GetThumbnail hanging on slide

I’ve got a powerpoint presentation where the GetThumbnail is hanging when called on one particular slide. It causes the CPU to lock 100% for what seems forever (only waited hours so far). Without these bullets the slide processes within milliseconds.

I’ve attached the powerpoint presentation. If I resize the box the powerpoint works.

I’m running ASPOSE Slides inside a windows service using .NET 4.5 running on Windows Server 2012 and 2008 R2.

I’m using the below code to generate the preview image:

            Image fullImage = slide.GetThumbnail(1, 1);


Thanks for inquiring Aspose.Slides.

I have worked with the presentation files shared by you using Aspose.Slides for .NET 7.1.0 and have not been able to observe the issue specified. Please try using the specified version. For your kind reference, I have attached the generated thumbnail as well.

Many Thanks,
