I queried google for "ietf powerpoint presentation" and grabbed the first 10 results that were powerpoint files (9 ppt, 1 pptx): www.ietf.org/proceedings/56/slides/pwe3-7/pwe3-7.ppt tools.ietf.org/agenda/81/slides/tcpm-1.ppt tools.ietf.org/agenda/81/slides/mpls-12.pptx tools.ietf.org/agenda/81/slides/tsvwg-9.ppt www.mnot.net/papers/ietf-49-wrec.ppt www.mnot.net/papers/ietf-50-webi.ppt www.softarmor.com/xcon/meets/ietf62/04-xcon-netconf.ppt www.oasis-open.org/presentations/security/SBradner.ppt www.cdnc.org/gb/news/download/RFJ47th-IETF.ppt tools.ietf.org/agenda/81/slides/idr-3.ppt I used a local build of LibreOffice to open up the files and convert them to PDF/A-1a, then ran them through a PDF validator (http://www.pdf-tools.com/pdf/validate-pdfa-online.aspx). Of the 10 files, all validated successfully except for idr-3.pdf. The pdf file appears fine, the validator just gives an error about an unknown 'DCTDecode' filter. I'm sure that PDF validators aren't perfect, but the quick test seems to indicate that LibreOffice is pretty good at creating valid PDF/A output. Because it is free (and Free), and has builds for just about every platform, LibreOffice could be given to any contributor/author who asks for help exporting materials to PDF/A. -- Robinson _______________________________________________ Ietf mailing list Ietf@ietf.org https://www.ietf.org/mailman/listinfo/ietf
