how to combine all bytearrayoutputstream after manipulating the pdf. I want
to get the whole baos that represents the pdf. I need help on this coz I am
getting blank page or corrupted pdf if I use one baos for the whole passes.
In the example in the book, if I used different baos, how to combine them in
order to have one pdf? I need to get the baos.toByteArray which represents
the pdf. Please help.
from the example in the book:
/* chapter02/HelloWorldStampCopy.java */
RandomAccessFileOrArray letter =
new RandomAccessFileOrArray("HelloLetter.pdf");
reader = new PdfReader(letter, null);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
stamper = new PdfStamper(reader, baos);
form = stamper.getAcroFields();
form.setField("field", "World,");
stamper.setFormFlattening(true);
stamper.close();
/* chapter02/HelloWorldStampCopy.java */
reader = new PdfReader(baos.toByteArray());
Document document =
new Document(reader.getPageSizeWithRotation(1));
PdfCopy writer = new PdfCopy(document,
new FileOutputStream("HelloWorldStampCopy.pdf"));
document.open();
writer.addPage(writer.getImportedPage(reader, 1));
/* chapter02/HelloWorldStampCopy.java */
reader = new PdfReader(letter, null);
baos = new ByteArrayOutputStream();
stamper = new PdfStamper(reader, baos);
form = stamper.getAcroFields();
form.setField("field", "People,");
stamper.setFormFlattening(true);
stamper.close();
reader = new PdfReader(baos.toByteArray());
writer.addPage(writer.getImportedPage(reader, 1));
If I get the baos.toByteArray() here, I will only get the last page coz
there multiple instance of baos.
