I opened a PPTX file containing only a chart as an Aspose.Slides.Pptx.PresentationEx object and immediately saved the presentation in PPTX format.
Upon opening the output presentation in PowerPoint, PowerPoint reports that the presentation is corrupted.
The following code is an example of the method I used:
AsposePresentation = new Aspose.Slides.Pptx.PresentationEx("source.pptx");
AsposePresentation.Save("AsposeOutput.PPTX", Aspose.Slides.Export.SaveFormat.Pptx);
(Source.pptx is 45,461 bytes, AsposeOutput.PPTX is 40851 bytes)
