Here are some code pointers:
https://opengrok.libreoffice.org/search?project=core=AdditionalStreams==full

To create the pdf:
emitTrailer() method from vcl/source/gdi/pdfwriter_impl.cxx

The rest seems related to PDF import

Indeed the hybrid PDF functionality  i s   a great innovation.
However it could even then have been (and still can be implemented) by using
the standard conforming method of embedding the source file.

If done, this would have the advantage that every standard compliant PDF
viewer or PDF processing software could auto-discover the embedded source
file and let the user "do something" with it even in the absence of a
LibreOffice installation on his system.

Thank you Michael for your very quick feedback! :-)

I took a look at
https://www.adobe.com/content/dam/acom/en/devnet/pdf/pdfs/pdf_reference_archives/PDFReference.pdf
which 1.4 version (released in 2001 according to
https://fr.wikipedia.org/wiki/Portable_Document_Format#Versions). Version 1.4
had already "EmbeddedFiles" keyword (see 3.3 part).
So wondered why adding the non standard "AdditionalStreams" whereas this
keyword was existing. 
Or perhaps I wrongly understood this?

The hybrid PDF functionality was a great innovation, and the standard didn't
cover it then of course. It would be great to find some resources / and/or
interested people to implement the new standard using EmbeddedFiles. Alexis -
are you interested in some code pointers there ? hacking the core to rename a
few attributes and re-structuring the stream is likely to be a good start. I
imagine a Collaboran would be happy to mentor someone that wanted to work on
this themselves, but we can't resource a fix absent a customer ourselves today.

Michael/Miklos/Tomaž: I don't know who's PDF expert so thought one of you might
have some idea.

The problem here is "AdditionalStreams" keyword doesn't exist in PDF standard.
Taking a look at git history of d217c079d7b3ca7b5039428594e7cdfdf9a0c4a9, it's
been added with:

Shouldn't it be removed, put in readonly (I mean LO may read this on old files
but should replace the keyword when modifying) or at minimum make this
deprecated?
Instead there's "EmbeddedFiles" in specs (see
https://www.adobe.com/content/dam/acom/en/devnet/pdf/pdf_reference_archive/pdf_reference_1-7.pdf)

LO should respect PDF standard, I put this one to normal importance but it
should be even higher than this.

--- Comment #12 from Alexis de Lattre  ---
It is very very strange that a project such as LibreOffice that promote the
OpenDocument standard and interoperability in general doesn't respect the PDF
standard ! Adding proprietary keys in the PDF trailer that only LibreOffice can
read is certainly a bad practice. Using the "Embedded Files" feature of the PDF
standard is clearly the way to go !

It could be the occasion to add support for Embedded Files in the LibreOffice
PDF export. Embedded Files in PDF is starting to be a widely used feature with
electronic invoicing standards such as Factur-X/ZUGFeRD that use the Embedded
Files feature of the PDF standard to add an XML file in a PDF invoice (to allow
automatic processing of the invoice), and the possibility to add other document
as attachments of the PDF (documents that justify the invoice, for example a
signed acceptance form).

For instance, I recently developed a LibreOffice extension to be able to
generate Factur-X invoices from LibreOffice Calc (cf
https://github.com/akretion/factur-x-libreoffice-extension). This extension
contains a Python macro that post-processes the PDF file generated by
LibreOffice to add the XML file as attachment to the PDF. The code of this
macro would be much simpler if the PDF export feature of LibreOffice had native
support for Embedded Files. And generating structured electronic invoices (with
Factur-X, ZUGFeRD or other standards) is starting to be compulsory in some
countries (for example, it is now compulsory in France when you invoice the
public sector).

** Please read this message in its entirety before responding **

To make sure we're focusing on the bugs that affect our users today,
LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed
bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this
bug report. During that time, it's possible that the bug has been fixed, or the
details of the problem have changed. We'd really appreciate your help in
getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice
from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information
from Help - About LibreOffice.

If the bug is NOT present, please set the bug's Status field to
RESOLVED-WORKSFORME and leave a comment that includes the information from Help
- About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular
meaning that is not 
appropriate in this case)


If you want to do more to help you can test to see if your issue is a
REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your
bug pertains to a feature added after 3.3) from
http://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword

(In reply to Jos van den Oever from comment #9)
> PDF documents created with version 5.1.2.2.0 on Linux 4.4 still add the key
> /DocChecksum and /AdditionalStreams to the PDF files.

Jos, the additional (proprietary) keys used by OpenOffice/LibreOffice to embed
the original OpenDocument file into the Hybrid PDF are not doing any real
h a r m:

  * As I showed in comment #6 none of the 36 tested PDF viewers has any problem
opening and displaying a Hybrid PDF!

There are other reasons which would may  M E  want to modify the way LO creates
a Hybrid PDF:

  * N O N E  of the other PDF readers do have a way to detect that there is an
embedded OpenDocument file in the PDF!

The reason for this is that the way OO/LO implemented this feature was that
they did it in a non-standard, "proprietary" way -- while they could have
utilized the standards-defined "embed another file into the PDF"-feature. (See
for example bug95328 and comments).

And there  A R E  good use cases to be able to detect the embeddedness of the
original OpenDocument file in a PDF even by non-OO/LO applications:

  - User(s) may not be aware of this when they open the PDF in a PDF reader.
However, the reader may draw their attention to the fact of the original
ODT/ODS document being embedded. After all, whoever embedded the original
document into the Hybrid PDF most likely  W A N T E D  it to be editable.

  - Users may need/want to extract the embedded ODT/ODS file without switching 
to LibreOffice first (which may not even be installed on their currently
used computer system).

  - I could easily think of more use cases, why it would be good to be able to
D E T E C T  the fact of the embedded original and editable file and also
to  E X T R A C T  it from the PDF via a software other than OO/LO.

According to these test results:

   
https://docs.google.com/spreadsheets/d/1Ok37dvlRSpzKpdKJ6gYycM5QzM7sv4_YCybHbiFMVFI

none of 36 different PDF viewers or applications did have a problem to display
or process the tested hybrid PDF created by LibreOffice.

Hence I took the liberty to set importance of this bug to much lower for now. I
won't protest if someone even closed it as WONTFIX unless there appears other
evidence of real life problems...

Hi Jos,
Thanks for the report.
I set this to New, trusting your expertise in this ;)
Is this an issue new with the 410beta2 or already in older versions too?
Best,
Cor
