--------------------------------------
Description:
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);
opdf.addPage(pag1);
}
else
{
pag1 = opdf.importPage(ipdf.getPage(0));
}
// STREAM 1
PDPageContentStream stream = new PDPageContentStream(opdf, pag1,
AppendMode.APPEND, true, true);
stream.setNonStrokingColor(Color.BLUE);
stream.beginText();
stream.setFont(PDType1Font.HELVETICA, 15f);
stream.newLineAtOffset(10, 780);
stream.showText("pag 1");
stream.endText();
stream.close();
PDPage pag2;
if (addPage)
{
COSDictionary dic2 = new COSDictionary(ipdf.getPage(1).getCOSObject());
pag2 = new PDPage(dic2);
opdf.addPage(pag2);
}
else
{
pag2 = opdf.importPage(ipdf.getPage(1));
}
// STREAM 2
PDPageContentStream stream2 = new PDPageContentStream(opdf, pag2,
AppendMode.APPEND, true, true);
stream2.setNonStrokingColor(Color.BLUE);
stream2.beginText();
stream2.setFont(PDType1Font.HELVETICA, 15f);
stream2.newLineAtOffset(10, 760);
stream2.showText("pag 2");
stream2.endText();
stream2.close();
PDPage pag3;
COSDictionary dic3;
if (addPage)
{
dic3 = new COSDictionary(ipdf.getPage(0).getCOSObject());
pag3 = new PDPage(dic3);
opdf.addPage(pag3);
}
else
{
pag3 = opdf.importPage(ipdf.getPage(0));
}
// STREAM 3

stream3.newLineAtOffset(10, 730);
stream3.showText("pag 3");

PDPage pag4;

{

pag4 = new PDPage(dic4);
opdf.addPage(pag4);
}

{

}
// STREAM 4

stream4.newLineAtOffset(10, 730);
