How to convert pdfstamper to byte array -

in application, need read existing pdf , add together barcode existing pdf , pass output stream. here existing pdf template. using itext jar adding barcode.

i want know possibilities of converting pdfstamper object byte array or pdfcontentbyte byte array. can help on this?

your question unclear. assume want write bytearrayoutputstream instead of fileoutputstream. there different examples on how on itext web site.

see instance formservlet illustration says:

// create outputstream new pdf bytearrayoutputstream baos = new bytearrayoutputstream(); // create pdf pdfstamper stamper = new pdfstamper(reader, baos);

then later in example, this:

// write pdf bytes outputstream outputstream os = response.getoutputstream(); baos.writeto(os);

if want byte[], can this:

byte[] pdfbytes = baos.tobytearray();

i hope question wasn't writing pdfcontentbyte stream byte[] because wouldn't create sense: content stream doesn't contain resources such fonts, images, form xobjects, etc...
