Its pretty much the reverse of what was needed in your post from a couple of weeks ago about extracting an image from a watermark.

In other words, you need to add a header with a watermark (which is an image).

To add a header, you have to add the header part, and insert a reference to it in w:sectPr.

You want to add the header part to the main document part. So you do something like:

Code: Select all
Relationship relationship = wordprocessingMLPackage.getMainDocumentPart().addTargetPart(headerPart)

Same general idea for adding an image part to the header part.

Now, you have a couple of ways in which to set up the contents for the header part.

1. You can do it programmatically, or

2. You can use an existing XML representation of the part (created in Word for example, and saved as a file or a string).

Which works best for you will depend on your specific circumstances.

Attached below is some code I had lying around which you could adapt for your purposes.
