iText : How do I insert background image in the same document to be flushed to response

Question

I am creating a PDF and writing the stream in response. Before writing in the stream, I want to add a background image as watermark in all the pages so that PDF document flu

Answer 1

You can choose between two options:

1. Use the background image in a page event (to the 'under' content in the onEndPage() method)/
2. Create the first PDF in memory, then add the background image in a second pass using the code you posted.

I prefer option 1.
