             Summary: Duplicated text content in template
                 Key: PDFBOX-4614
                 URL: https://issues.apache.org/jira/browse/PDFBOX-4614
             Project: PDFBox
          Issue Type: Bug
            Reporter: michele valdinoci
             Fix For: 2.0.16
         Attachments: input.pdf

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. First and third output page have same texts ("page 1" and "page 3"!):

{{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());}}
 {{} 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();}}{{opdf.addPage(pag1);}}{{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}}
 {{PDPageContentStream stream3 = new PDPageContentStream(opdf, pag3, AppendMode.APPEND, true, true);}}
 {{stream3.setNonStrokingColor(Color.BLUE);}}
 {{stream3.beginText();}}
 {{stream3.setFont(PDType1Font.HELVETICA, 15f);}}
 {{stream3.newLineAtOffset(10, 730);}}
 {{stream3.showText("pag 3");}}
 {{stream3.endText();}}
 {{stream3.close();}}{{PDPage pag4;}}
 {{if (addPage) {}}
 \{{ COSDictionary dic4 = new COSDictionary(ipdf.getPage(1).getCOSObject());}}
 \{{ pag4 = new PDPage(dic4);}}
 \{{ opdf.addPage(pag4);}}
 {{} else {}}
 \{{ pag4 = opdf.importPage(ipdf.getPage(1));}}
 {{}}}
 {{// STREAM 4}}
 {{PDPageContentStream stream4 = new PDPageContentStream(opdf, pag4, AppendMode.APPEND, true, true);}}
 {{stream4.setNonStrokingColor(Color.BLUE);}}
 {{stream4.beginText();}}
 {{stream4.setFont(PDType1Font.HELVETICA, 15f);}}
 {{stream4.newLineAtOffset(10, 730);}}
 {{stream4.showText("pag 4");}}
 {{stream4.endText();}}
 {{stream4.close();}}{{opdf.save("out.pdf");}}{{ipdf.close();}}
 {{opdf.close();}}
