Hi,
I currently can't try it myself but
PDDocument document = PDDocument.load(…)
PDPage pageToInsert = new PDPage();
PDPageTree pageTree = document.getPages();
COSDictionary pagesDictionary = (COSDictionary)
document.getDocumentCatalog().getCOSObject().getDictionaryObject(COSName.PAGES);
COSArray kids = (COSArray)
pagesDictionary.getDictionaryObject(COSName.KIDS);
kids.add(0,pageToInsert.getCOSObject());
pageToInsert.getCOSObject().setItem(COSName.PARENT, pagesDictionary);
pagesDictionary.setInt(COSName.COUNT,
pagesDictionary.getInt(COSName.COUNT) + 1);
document.save(...);
document.close();
Heh heh, after having looked at the source code, I think this should
work fine. I thought there is some caching, but there isn't.

Thanks,
I have implemented it using merge, but unfortunately that almost
doubles my processing time :-(
The steps my app takes:
1. I take a PDF of almost 2000 pages and add a footer to each page.
This takes about 12 seconds.
2. I then create a PDF which has my single cover page.
3. I merge the two PDFs together. This takes an additional 10 seconds.
I guess that if we had the ability to insert a page then it would be
much faster than a merge?

Hey there,
I want to add a cover page to a PDF, i.e. add a new *first* page to an
existing PDF.
I managed this with 1.8.0 by manipulating the page nodes via
PDPage#setParent, however I can't figure out how to do this with
2.0.0-SNAPSHOT.
Can anyone tell me how to insert a new page at index 0 for an existing
PDF?
Perhaps subsequently adding an example to
https://svn.apache.org/viewvc/pdfbox/trunk/examples/src/main/java/org/apache/pdfbox/examples/pdmodel/
could help others?
You can't... unless you create a new PDDocument with the cover page and then
run a merge.
Your feature request already has an issue:
https://issues.apache.org/jira/browse/PDFBOX-2400
