[iText-questions] Resizing a pdf and keeping original metadata

[Cesar Romani]

I'm using the following code to resize a pdf to width=553 and
height=714:

--------------------
[...]
public static void main(String[] args) {
try {
if (args.length < 2) {
System.out.println("Pdf resizer");
System.out.println("Args: pdf_in pdf_out");
System.exit(2);
}
float Width=553;
float Height=714;
PdfReader reader = new PdfReader(args[0]);
Document doc = new Document(new Rectangle(Width, Height));
PdfWriter writer = PdfWriter.getInstance(doc, new
FileOutputStream(args[1]));
doc.open();
PdfContentByte cb = writer.getDirectContent();

PdfImportedPage tp;
int pageNumber;
int NumberOfPages=reader.getNumberOfPages();
float Width2, Height2, WidthFactor, HeightFactor, factor;
float offsetX, offsetY;

for (pageNumber=1; pageNumber<=NumberOfPages; pageNumber++) {
tp = writer.getImportedPage(reader, pageNumber);
Width2 = reader.getPageSize(pageNumber).getWidth();
Height2 = reader.getPageSize(pageNumber).getHeight();
WidthFactor = Width / Width2;
HeightFactor = Height / Height2;
factor = Math.min(WidthFactor, HeightFactor);
offsetX = (Width - (Width2*factor))/2;
offsetY = (Height - (Height2*factor))/2;
cb.addTemplate(tp, factor, 0, 0, factor, offsetX, offsetY);
doc.newPage();
}
doc.close();
System.exit(0);
}
catch (Exception e) {
e.printStackTrace(System.out);
System.exit(1);
}
}
}
--------------------

The problem is that the metadata gets lost. How can I keep the original
metadata on the resized pdf?

Many thanks in advance,
--
Cesar
