--- Comment #11 from V Stuart Foote  ---
Issue remains with current master/6.3.0alpha0+, 

However as the OCR'd PDF is a bitmap, the text spans are annotation on that
image. Showing the annotation on import to Draw--where the PDF is broken out to
its component Draw elements--actually seems correct.

Inserting the PDF (pdfium based, but just the first page of PDF for now)
renders the PDF page as an image. 

The inserted "Image" can be selected and with "Break" split into its component
text and the scanned newspaper page. After break, the scanned image can be
selected and removed leaving just the OCR text as Draw text frames.  It is
slow, and utility of this is questionable--but then manipulating PDF content is
questionable. The text from a PDF is not intended to be manipulated.

--- Comment #10 from QA Administrators  ---
** 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


Feel free to come ask questions or to say hello in our QA chat:

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
QA Team

I've looked into this a bit more. The issue is that we don't (or perhaps can't
yet!) implement text rendering mode 3 - neither fill nor stroke text
(invisible).

See PDF 32000-1:2008 section 9.3.6 Text Rendering Mode.
