This will work correctly and will be smaller:
private PdfReader emptyPdfPage;
private PdfReader getEmptyPDFPage(){
if (emptyPdfPage==null){
ByteArrayOutputStream baos = new
ByteArrayOutputStream(1024);
try {
Document emptyDoc = new
Document(document.getPageSize());
PdfWriter w = PdfWriter.getInstance(emptyDoc,
baos);
emptyDoc.open();
emptyDoc.getDirectContent().setLiteral(' ');
emptyDoc.close();
}
catch (DocumentException ex) {
ex.printStackTrace();
throw new RuntimeException();
}
this.emptyPdfPage = new
PdfReader(baos.toByteArray());
}
return new PdfReader(emptyPdfPage);
}
