OH – I misunderstood your question/point.
You are saying that if you merge/append two documents, that it doesn’t merge
attachments. Yes? So that if you have a PDF with 1 attachment and one PDF with
2 attachments and merge them – you get a PDF with 3 attachments.
In that case, I agree with you that it should do that – and if it doesn’t, it’s
a bug…

Subject: Re: [Podofo-users] Appending PDF: Embedded files of appended file not
accessible in result pdf
I'd like to disagree there. If the framework gives me a high level option to
append a whole pdf document (which the Append function provides), I'm expecting
that it's doing just that, including the embedded file. On the contraty, if I
iterate over all pages and add each page sequentially, I wouldn't expect the
embedded files to be added as well (does this work?).
Even if we agree that the Append() function should only append the pages of the
given pdf file, there's still the effect that previously existing embedded
files are still hidden in the pdf, but cannot be accessed (evaluated by looking
at file sizes). That's inconsistent if we agreed that the function only appends
pages.
So I think, either something has to be done to make the embedded files
accessible again (where I would need help for) or the embedded files should be
ignored at all when using the Append() function, so the result pdf size won't
increase by the size of the previously existing embedded files.

<lrose...@adobe.com<mailto:lrose...@adobe.com>>:
Appending is not the same as Attaching.
Appending is what the name implies – append the pages from one to the other.
So that a appending a 10 page document to another 10 page document yields a
document with 20 pages.
Attaching is the same as it is with Email or using a ZIP file. You are adding
the files “inside of” the primary file – but not as part of the content.

Subject: [Podofo-users] Appending PDF: Embedded files of appended file not
accessible in result pdf
Hello dear podofo users,
recently I experimented with merging multiple pdf files into one pdf using the
Append function of PdfDocument. It works like a charm with the pdf pages and
annotations, but I recognised that attached files (at document root) of
appended pdfs are not listed in the attachment table of my pdf viewer (Foxit
8.0, didn't check other viewers I've got to admit). When checking the size of
my result pdf, it was clear that the embedded files are still there somewhere,
but I cannot access them it seems.
Is this the expected behaviour or did I stumble over a bug / missing feature
here? I think there might be a way to recreate the necessary internal
references, but I'm lacking the knowledge to do so. I could circumvent this
issue by manually extracting the embedded files (I know how to do that) and
adding them to the result pdf (trivial via AttachFile function), but I don't
know how to remove the embeeded files before appending the pdf file.
Thanks in advance,
Frederik
