Hello,
I would like to take one file, create with his contains another, and another
and another... (multiple time, for example to get a file, and make two,
after make four, ...).
My problem is that after the creation of two files, the last is unreadable
and I don't know what I do wrong... For my tests, I take one PDF (PDF_A)
from 1 page, and I create the PDF_B. After I take PDF_B to create PDF_C and
there PDF_C is unreadable (with Code using PDFBox, but I can open and read
it by the OS system). When I use the code below to read the new PDF, it see
just the contains : "\r\n"
Test with IText 2.1.4 and 2.1.7.
What I do wrong during the creation of the new file ?
Thanks

Code to create new PDF
------------------------------------
....
com.lowagie.text.Document document = new com.lowagie.text.Document(
reader.getPageSizeWithRotation(numberOfPage));
PdfWriter writer;
try {
File f = new File(nameOfNewFile);
if (f.exists()) {
...
}
writer = PdfWriter.getInstance(document,
new FileOutputStream(nameOfNewFile));
} catch (Exception e) {
...
succesfull = false;
continue;
}
document.open();
PdfContentByte cb = writer.getDirectContent();
PdfImportedPage page;
int rotation;
for (int pageNumber = pdfFromERP.pageBegin + 1; pageNumber
<= pdfFromERP.pageEnd + 1; pageNumber++) {
document.setPageSize(reader
.getPageSizeWithRotation(pageNumber));
document.newPage();
page = writer.getImportedPage(reader, pageNumber);
rotation = reader.getPageRotation(pageNumber);
if (rotation == 90 || rotation == 270) {
cb.addTemplate(page, 0, -1f, 1f, 0, 0, reader
.getPageSizeWithRotation(pageNumber)
.getHeight());
} else {
cb.addTemplate(page, 1f, 0, 0, 1f, 0, 0);
}
}
document.close();
