Ho do i merge two pdfs from byte arrays with different page sizes? I have
wrote the followin code, it merges them but the page sizes are the same.
public static byte[] mergePdfs(byte[] firstPdf, byte[] lastPdf)
ByteArrayOutputStream byteArrayOutputStream = null;
byte[] mergedPdf = null;
try{
Document document = new Document();
byteArrayOutputStream = new ByteArrayOutputStream();
PdfWriter pdfWriter = PdfWriter.getInstance(document,
byteArrayOutputStream);
document.open();
PdfContentByte pdfContentByte = pdfWriter.getDirectContent();
PdfImportedPage pdfImportedPage = null;
PdfReader pdfReader = new PdfReader(firstPdf);
for (int i = 0; i < pdfReader.getNumberOfPages(); i++) {
document.newPage();
pdfImportedPage = pdfWriter.getImportedPage(pdfReader, i + 1);
float width = pdfImportedPage.getWidth();
float height = pdfImportedPage.getHeight();
document.setPageSize(new Rectangle(width, height)); // doesent
work
pdfContentByte.addTemplate(pdfImportedPage, 0, 0);
}
pdfReader = new PdfReader(lastPdf);
for (int i = 0; i < pdfReader.getNumberOfPages(); i++) {
document.newPage();
pdfImportedPage = pdfWriter.getImportedPage(pdfReader, i + 1);
float width = pdfImportedPage.getWidth();
float height = pdfImportedPage.getHeight();
document.setPageSize(new Rectangle(width, height)); // doesent
work
pdfContentByte.addTemplate(pdfImportedPage, 0, 0);
}
document.close();
mergedPdf = byteArrayOutputStream.toByteArray();
}
