We are using Aspose.Slides 18.9.0 for .NET. In some PPTX files that we generate, we have embedded Excel OLE objects and have set a substitute picture via the IOleObjectFrame. Currently, after a user accesses the embedded OLE excel object, the substitute picture is removed and the OLE object frame is resized and replaced with an Excel icon.
Instead of disappearing with an icon or the updated Excel chart, we would to keep the substitute image while still being able to link to embedded data. Is this possible? And if so, could you please explain how this might be achieved?
