Removing multiple slides

I have a web page where the user selects which slides he would like to download from a PowerPoint, then Aspose.Slides removes the unselected slides and streams the copy to him.

The program worked very well with a PPT and Aspose.Slides; however, after porting to PPTX and Apose.Slides.Pptx, I am encountering an error. When opening the PPTX file, Powerpoint says it has encountered "unreadable content" and asks me if I would like to repair. Sometimes, this works, and other times, it does not.

I noticed that if I remove only one slide (any one), I do not get the error in PowerPoint. However, if I remove multiple slides, the error occurs.

Is this a known issue? Is there a workaround for it?

I played with the PowerPoint file some more and I believe something int he pptx document schema may have been corrupt. Doing a “Save As” of the original file produced another file that still could not remove multiple slides. However, creating a new empty presentation, and copying the masters and the first 10 slides into it, I was able to perform multiple removals. I think this can be considered an issue in PowerPoint and not Aspose.


HTH anyone who runs into similar issues in the future.
