Hi :)
I have played around with a few simple little files at home and found the 
increase is usually about 1% but occasionally reaches 5%.

Tom :)

I agree that providing accessible files is important and we should do

However, for many people download speed and filesize *are* still
important issues. Filesize not for storage after download, but for
counting against one's allowed download limits.

IMO, if we want to provide more accessible PDF files for those who want
or need them, we should have two sets of files: one without tagged PDF
and one with.

I don't know what makes tagged pdfs different from normal ones but apparently 

increases accessibility by making it easier for screen-readers.  Is it 
difficult?  Can new releases of chapters be in odt and tagged pdf?

The only reason that tagged PDF was not chosen to be the default in OOo when it 

was introduced is that file size noticeable increases (30-50%).

Something people cared about then, because PDFs should be small (download speed 

/ attachment size).

At least download speed shouldn't be an argument anymore.

Spreading better accessible PDFs is more important.

I had also planned to make tagged PDF the default in OOo 3.5, because we have 
been working on Accessibility stuff anyway.

So you really should do so.

So are you saying that simply ticking that box to make Pdfs tagged does a lot 

improve Accessibility even without doing anything extra to the document?  If 

then we need to bump that bug-report to higher importance in my opinion.

I for one would be very glad to know that Libre Office has this
feature.  It is not a complete and sure fire way to make a document
accessible but, I think it goes quite a long way.  It will probably
make the simpler pdf documents much easier to navigate for screen
reader users right out of the box since the navigation quick keys
which software like Jaws, Orca and NVDA have are pretty universal for
jumping through documents.  h for heading, t for table, p for
paragraph, etc.  In untagged pdf's these don't work.

Yes, the more bug-reports the better.  Especially very specific ones that
be fairly easy to fix.  There is a fork called NeoOffice that is targeted 
Macs and doesn't use the X system.

Hi guys,
I'm reading this tread with great interest.
I am not an expert-user of Libreoffice (the mac os X' version is still very
inaccessible!), but I wonder if libreoffice is able to perform a "serious"
accessibility check on PDF documents, not limited, of course, to the 
If it isn't, it should be great if this feature could be implemented in 
Libreoffice needs really more work on accessibility (I tested the MAC OS X'
By the way, about two months ago we were talking about the "accessibility
issues" in the mac OS X' version of LO. I would like to help to fix 
think i should report them as bugs?

Hi Tom,

Perhaps add "[wishlist]" to the subject-line?

OK, I did not know that tag existed.

I think post the bug-report now rather than leaving it.  Any small
in accessibility should be a priority in my opinion. Sometimes the
defaults are
not really thought about and are easy to change which helps new devs 
to do coding :)  A good win for everyone.

Is there a down-side to having Pdfs tagged by default?  What does the
option do?

"Tagged PDF contains information about the structure of the document
This can help to display the document on devices with different screens,
when using screen reader software. "

Exporting an inaccessible document as "tagged PDF" may give people the
impression that a document is accessible when they do only a superficial
(e.g. Adobe Reader's so-called accessibility check only checks whether the
is tagged or not).
I would also want to avoid that authors get the false idea that checking
"tagged PDF" is all they need to do to produced accessible PDF. (Although 

doubt that changing the default setting will make a difference to this 

Best regards,


Regards from Tom :)

Subject: [libreoffice-accessibility] Should Writer export tagged PDF and
bookmarks by default?
Hi, I have been thinking about ways to improve accessible authoring in
LibreOffice Writer. As far as I know, Writer (in and in
LibreOffice) is the only open source office software that can export
tagged PDF,
which is important for accessibility. When you open the PDF Options 
->  Export as PDF...), the options "Tagged PDF" and "Export bookmarks" on
General tab and the option "Bookmarks and page" on the Initial View tab
unchecked by default. When you check them, they remain checked for later
commands. However, wouldn't it be better if these options were checked by
default? Checking these options does not magically make your PDF 

accessible, because that depends on the quality of the ODF source. So
should we
request this feature now or should we wait until an accessibility checker
Writer becomes available? Best regards, Christophe
