使用PdfBox，如何将PDDocument的内容检索为字节数组？

Question

I am currently using PdfBox as the driver for a pdf-file editor application. I need the contents of the PdfBox representation of a pdf file (PDDocument) as a byte array. Does anyone know how to do this?

Answer 1

I hope it's not too late...

ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
document.save(byteArrayOutputStream);
document.close();
InputStream inputStream = new ByteArrayInputStream(byteArrayOutputStream.toByteArray());

And voila! You've got both input streams!
