Plutext

I tried using

Code: Select all

presentationMLpackage.getParts().get(new PartName("/ppt/slides/slide6.xml")).setPartName((new PartName("/ppt/slides/slide6-1.xml"));


This does change the name of the part; however, the [Content_Types].xml file doesn't get updated.
How do I update the content types?

See MainPresentationPart's addSlideIdListEntry for what needs to be done

Hi Jason,

I tried doing this:

Code: Select all

//rename part
presentationMLPackage.getParts().get(new PartName("/ppt/slides/slide6.xml")).setPartName(new PartName("/ppt/slides/slide6-1.xml"));
SlidePart tempPart = (SlidePart) presentationMLPackage.getParts().get(new PartName("/ppt/slides/slide6-1.xml"));
presentationMLPackage.getMainPresentationPart().addSlideIdListEntry(tempPart);


But the problem still remains.

What is your objective?

I have a function that duplicates slides:

public void createDuplicateSlide(String slidePartName, int n)

This is how I use it:
createDuplicateSlide("ppt/slides/slide6-1.xml",3)

so that I have:
ppt/slides/slide6-1.xml
ppt/slides/slide6-2.xml
ppt/slides/slide6-3.xml
ppt/slides/slide6-4.xml

But as you can see, the problem is the fact that the first slide needs to be named slide<number>-1.xml.

I was wondering if there was a simple way I could rename slide<number>.xml to slide<number>-1.xml.

I could, of course, start naming from slide<number>-2.xml for the duplicates; however, this leads to
complications later in my program where I try to split the contents of a table across several slides.

Is there an easy fix to this?

I think it is easy provided you are happy for your duplicate slides to use a single notes slide (and assuming Powerpoint and other consumers are ok with that), and where the slide has references to images etc, your duplicate slides can/do just use a copy of the slide's rels part (again, pointing to the original objects).

If you post your method, I'll have a quick go at it.

Otherwise, Plutext's MergePptx can do this sort of thing for you, but that's a commercial extension.
