Merging Powerpoint decks using Apache POI

Question

I have a folder of several ppt decks that I want to combine into one deck. I do not see any easy way to add a slide from deck to another. Is there a function that handles this? Is there another Java library that can do this?

Thank you!

Answer 1

I don't think you'll find pure java solution.

When doing some ppt reads/updates I had to move away from apache POI implementation, that seems to be quite limited.
I finally ended up with Libreoffice/OpenOffice + some java wrapper (that did the specific thing I needed)

Based on the similar/almost identical question/problem: Copy PowerPoint Slides in Java (preferably) and non-java based solution as the answer it probably only supports my theory of Apache POI capabilities in this area :(

Answer 2

Disclosure: I oversee the docx4j/pptx4j project

I just wrote code to do this using pptx4j, so it is definitely do-able in Java for pptx files, using open source tools.
