Please provide links to any documentation needed to start contributing to it.
Also, for PowerPoint File format, what specification is being followed.

Please see http://poi.apache.org/guidelines.html for details on how to
contribute, links to the official file format specs etc

However... I think you can do what you want with POI already. Just copy the
master slideshow to a new file, open it, and delete all the slides you don't
want

Thanks Nick for the suggestion. But the problem with this approach is
redundancy and time/resource consuming. For eg, I have 20 slides SlideShow file
and I want to get 20 new SlideShow having a single slide. So, performing 19
delete operations for every SlideSHow is not efficient.

The alternative would be to copy each slide to a new presentation, by creating
a new slide in the new presentation and importing the content of the original
slide into the newly created slide.
https://poi.apache.org/apidocs/org/apache/poi/xslf/usermodel/XSLFSlide.html#importContent-org.apache.poi.xslf.usermodel.XSLFSheet-

But then you would have to copy the master style sheet and some other details,
from the original presentation to the newly created presentation.

If your slides have charts or notes and you want to copy them along, you would
face bug #57835 for which I implemented only part of the fix: charts in the
same presentation.

Not wanting to scare you, but Nick might have given the path to the solution
with less code to write...

If I would like to contribute this feature can anyone please point me to area
in codebase/documentation that I should look into. Starting from specifications
seems to be difficult to start with. Any help appreciated.
