iText：成功调整一页pdf的大小，但在pdf文档中有多页时失败

doc.newPage()

public void resize (float x, float y, float scale) throws Exception {    PdfReader reader = new PdfReader(pdfIn);    document doc = new document(PageSize.LEGAL, 0, 0, 0, 0);    PdfWriter writer = PdfWriter.getInstance(doc, new FileOutputStream(pdfOut));    doc.open();    PdfContentByte cb = writer.getDirectContent();    for(int i=1; i<=reader.getNumberOfPages(); i++){        doc.newPage();        PdfimportedPage page = writer.getimportedPage(reader, i);        cb.addTemplate(page, scale, 0, 0, scale, x, y);    }    doc.close();}
