Hi! I should implement a program that uses PDF document as a template
and adds content from text file over the template. The current
implementation below works if template is made with OO3 Writer. However,
if the template pdf is created with OO3 Draw, only the template content
is displayed in the resulting pdf.
I tried also layers but result is the same. Even if the template is in a
"lower" layer and text content in a "higher" layer, the text content is
displayed in Adobe Reader only if the lower layer is hidden.
So, how should I change the program to make work also with a template
pdf created with OO3 Draw?

public static void main(String[] args) throws Exception {
if (args.length != 3) {
System.err.println("Usage: java -jar merge.jar pdf_in txt_in
pdf_out");
}
String pdfIn = args[0];
String textIn = args[1];
String pdfOut = args[2];
PdfReader reader = new PdfReader(pdfIn);
Document document = new Document(PageSize.A4);
PdfWriter writer = PdfWriter.getInstance(document, new
FileOutputStream(pdfOut));
document.open();
PdfContentByte cb = writer.getDirectContent();
document.newPage();
PdfImportedPage page1 = writer.getImportedPage(reader, 1);
cb.addTemplate(page1, 1, 0, 0, 1, 0, 0);
Paragraph paragraph = new Paragraph();
paragraph.setLeading(0.5f, 0.5f);
File file = new File(textIn);
BufferedReader in = new BufferedReader(new FileReader(file));
String line;
StringBuffer buffer = new StringBuffer((int) file.length());
while ((line = in.readLine()) != null) {
buffer.append(line);
buffer.append('\n');
}
paragraph.add(new Chunk(buffer.toString(), new Font(Font.COURIER, 7,
Font.NORMAL)));
document.add(paragraph);
document.close();
}
