How to export accessible PDF

[giamma]

Hello,

how do you ask unoconv to switch on accessible PDF export in LibreOffice?
e.g.

Sorry to push, any feedback for this request?

I don't know if there is any LibreOffice documentation for what the export options are actually called, but if there is, that's where you need to look. If there isn't, then your guess is as good as mine.

There weren't any command-line options although nothing indicated that. It seemed as if the last setting within the used profile was used.

As of LibreOffice 7.4, you can do this with headless office:

soffice --convert-to 'pdf:writer_pdf_Export:{"SelectPdfVersion":{"type":"long","value":2}, "UseTaggedPDF": {"type":"boolean","value":true}, "PDFUACompliance": {"type":"boolean", "value": true}}' test.odt

(See https://ask.libreoffice.org/t/solved-convert-to-pdf-with-specific-settings-from-command/40192/5)

But if I try and use that syntax with unoconv I get a parsing error from unoconv:

unoconv -f pdf -e '{"SelectPdfVersion":{"type":"long","value":2},"UseTaggedPDF":{"type":"boolean","value":true},"PDFUACompliance":{"type":"boolean","value":true}}' -o uno2.pdf test.odt 
/usr/bin/unoconv:19: DeprecationWarning: The distutils package is deprecated and slated for removal in Python 3.12. Use setuptools or check PEP 632 for potential alternatives
  from distutils.version import LooseVersion
Warning: Option {"SelectPdfVersion":{"type":"long","value":2},"UseTaggedPDF":{"type":"boolean","value":true},"PDFUACompliance":{"type":"boolean","value":true}} cannot be parsed, ignoring.

Because it goes through UNO, I wouldn't know what's the correct syntax there or whether it is at all supported.

Hi answering my own question this works for me

unoconv -e EnableTextAccessForAccessibilityTools=true -e UseTaggedPDF=true [other parameters]

Hi there, I now added

unoconv -f pdf -e EnableTextAccessForAccessibilityTools=true -e SelectPdfVersion=2 -e UseTaggedPDF=true -e PDFUACompliance=true

This seems indeed to work, at least for 7.6 on Windows. First tried it on Linux, but there I have a hard time for unoconv to look at different installations than the one that came with Ubuntu is 7.3.

Most machine-checkers seem pretty satisfied with the output.
