We have recently put Aspose.Slides into production creating presentations from templates. It is going well for the most part.
Big problem we are having now is that cloning does not work well. I have documented in the attached file that the Bold and FontName attributes of the portions of a PlaceholderEx do not get cloned. I may just be a little picky, but it does seem that cloning means that the clone is EXACTLY the same as the original. I just worry that there are more items getting dropped.
Please let me know when this gets fixed. In the meantime, I am going to write a workaround for the problem.
