My approach was wrong, I think. I needed to use createInputStream for what
I was after, not createOutputStream... Anyway, thanks for looking into it!

OK, I see... I thought it would be an OutputStream object, but casting to
that didn't work, but casting to FilterOutputStream does work.
I don't think I'll be able to use that to directly open the attached PDF
file, though, or is there a way to do it after all?

Your screenshot shows COSStream.$1. That's an anonymous class in
COSStream. And this is the code in COSStream that is used:
return new FilterOutputStream(cosOut)
{
@Override
public void write(byte[] b, int off, int len) throws
IOException
{
this.out.write(b, off, len);
}
@Override
public void close() throws IOException
{
super.close();
setInt(COSName.LENGTH, (int)randomAccess.length());
isWriting = false;
}
};
So your class is a FilterOutputStream, which is an OutputStream.

Sorry, I see that PDEmbeddedFile extends PDStream, so that is the
right function.
Then how do you explain this (see the output in the Console)?
I don't see anything because your image was an attachment (mine too but
Thunderbird makes them inline) and your attachment was removed by
Apache. You'll have to upload it somewhere.

You're looking in the wrong place. Look under PDEmbeddedFile's
createOutputStream method. What does it return?

Hi all,
I'm trying to load an embedded PDF file as a new PDDocument
object so I can
read its contents and the way to do it seems to be to get
the
output stream
from PDStream, convert it to an ByteArrayOutputStream and
then
load that
directly.
However, when I call the createOutputStream method of my
PDStream object,
the output is a COSStream object, not a OutputStream one, as
both the
internal method reference and the online documentation
suggest
it should be
(See:
https://pdfbox.apache.org/docs/2.0.13/javadocs/org/apache/pdfbox/pdmodel/common/PDStream.html#createOutputStream
<
https://pdfbox.apache.org/docs/2.0.13/javadocs/org/apache/pdfbox/pdmodel/common/PDStream.html#createOutputStream
--
).
Is this an incorrect documentation or implementation? What
can
I do to
overcome this issue and load the COSStream object as a new
document?
I'm using PDFBox 2.0.23, by the way.
Regards, Gilad.
