Thanks Ning Zhao.
My problem was fixed by this peace of code:
PdfReader reader = new PdfReader(sciezkaout + pliki[0]);
PdfCopy copy = new PdfCopy(document, new
FileOutputStream(sciezkaout + "sklejony.pdf"));
document.open();
Rectangle crop = reader.getCropBox(1);
PdfDictionary pagedict;
for (String aPliki : pliki) {
reader = new PdfReader(sciezkaout + aPliki);
int nu_pages = reader.getNumberOfPages();
for (int j = 1; j <= nu_pages; j++) {
if (crop.getWidth() != reader.getCropBox(j).getWidth() &&
crop.getHeight() != reader.getCropBox(j).getHeight()) {
pagedict = reader.getPageN(j);
pagedict.put(PdfName.MEDIABOX, new PdfRectangle(15, 0,
582, 820));
}
copy.addPage(copy.getImportedPage(reader, j));
}
}
document.close();
Fortunetly i haven't had use your code, but thanks anyway.
Pozdrawiam,
Paweł Gawędzki

Subject: Re: [iText-questions] is it possible to grab and move whole content of
pdf ?
Hi Pawel,
here is my code to centre the content while changing the page size.
----------------------- code --------------------------------------
// urx is the upper right x of the target page size // ury is the upper right y
of the target page size public void changePageSize(float urx, float ury, String
outputURI) {
Rectangle oldCropbox = reader.getCropBox(1);
float oldCWidth = oldCropbox.getWidth();
float oldCHight = oldCropbox.getHeight();
float deltaW = (float) (urx - oldCWidth);
float deltaH = (float) (ury - oldCHight);
if (log.isLoggable(Level.FINE)) {
log.fine("delta width: " + deltaW);
log.fine("delta hight: " + deltaH);
}
float oldLlx = 0f;
float oldLly = 0f;
float oldUrx = oldCWidth;
float oldUry = oldCHight;
float newLlx = oldLlx;
float newLly = oldLly;
float newUrx = oldUrx;
float newUry = oldUry;
if (deltaW > 0) {
newLlx = -deltaW / 2 + oldLlx; // 0 is the original llx
newUrx = deltaW / 2 + oldUrx;
if (log.isLoggable(Level.FINE)) {
log.fine("new llx: " + newLlx);
log.fine("new Urx: " + newUrx);
}
}
if (deltaH > 0) {
newLly = -deltaH / 2 + oldLly; // 0 is the original lly
newUry = deltaH / 2 + oldUry;
if (log.isLoggable(Level.FINE)) {
log.fine("new lly: " + newLly);
log.fine("new ury: " + newUry);
}
}
Rectangle pageSize = new Rectangle(newLlx, newLly, newUrx, newUry);
PdfDictionary dict = reader.getPageN(1);
dict.put(PdfName.CROPBOX, new PdfRectangle(pageSize));
dict.put(PdfName.MEDIABOX, new PdfRectangle(pageSize));
PdfStamper stamper = new PdfStamper(reader, new
FileOutputStream(outputURI));
stamper.close();
}
---------------------------- code ----------------------------------
in my case I was enlarging the page size. You may need to adjust the code to
fit your need.
This code works for me, but I'd like very much to know eleganter solution.
Best Regards,
Ellen N. Zhao
