I looked into the ASPOSE.Powerpoint evaluation component and the API.
One problem I came across is that it cannot access text placeholders inside tables as in PowerPoint.
In Microsoft.Office.Interop.PowerPoint this is possible by using PowerPoint.Shape.Table
Also other than inserting a watermark, is there any other changes done to the output in the evaluation version?
Thanks for your interest in Aspose.PowerPoint component.
1. Text placeholders inside tables will be supported in the next hot fix. It will be published on this week.
2. Evaluation version doesn’t have any changes except watermark.
Grouped frames and tables were implemented.
