I am using libreoffice 18.104.22.168 on CentOS 64 bit. I am trying to export some pptx files to pdfs. When i check the option “PDF/A1-a” the export is very slow, it takes around 45 seconds for 3 slides. The same pptx file gets exported in 3-4 seconds if i do not check this option.
I would like to export pptx files as PDF/A-1a spec pdfs. Any idea how to make this export faster ?
