> I'm trying to create a pdf, starting from another on, using "template" techinque to optimize
output size when pages is repeated. I will print text values with PDPageContentStream for
each page. From the second import of first page, all written texts are duplicated also in
page 1!
> In this sample I compose pdf with input page in sequence: 1, 2, 1 finally 2 (view attached
output.pdf). First and third output page have same texts ("page 1" and "page 3"!):

> {code:java}
> boolean addPage = true;
> PDDocument ipdf = PDDocument.load(new File("input.pdf"));
> PDDocument opdf = new PDDocument();
> PDPage pag1 = null;
> COSDictionary dic1 = null;
> if (addPage)
> {
>     dic1 = new COSDictionary(ipdf.getPage(0).getCOSObject());
>     pag1 = new PDPage(dic1);
>     System.out.println(pag1.getArtBox().toString());
>     System.out.println(pag1.getBBox().toString());
> }
