I'm using Aspose.Slides 5.6, but the problem is also present in the latest version.
When trying to load some PTTX files from an ASP.NET application, the application no longer responds and gets stuck at 99% of CPU.
Minimal code extract (from a method to convert from PPTX to PDF):
using (MemoryStream docStream = new MemoryStream(document, true)) // document is of type byte
using (MemoryStream pdfStream = new MemoryStream())
PresentationEx presEx = new PresentationEx(docStream);
The strange thing is that the same thing works locally, from Visual Studio (whether in Debug or Release mode), but doesn't work when deployed on a distant server.
This is only with certain PPTX files, others work fine. Attached is a simple PTTX file that causes issues.
