I listened to the German document. The picture at the top is read as “Bundesadler”, so an alternate text is found and used. The rest is just verbatim text-to-speech. Hi Matthias,
I think the following may work (could you test it?):
\setupbackend[format=pdf/ua-1] \setuptagging[state=start] \setupstructure[state=start] \setupbackend [format=PDF/A-3a, intent=sRGB IEC61966-2.1, level=0]
\setupexternalfigures[location=default] \starttext \externalfigure[cow][label={this is a cow}] \stoptext
At least, the validator only complains for the use of /DocumentFragment (unknown to PDF-1.7).
I think that (cf the tagging.pdf manual) \enabledirectives [backend.usetags=crap] should work and one can define ones own mappings
BTW, the use of \setupbackend is mandatory when you add images (these are color profiles).
i'm currently trying to make this profile mess a bit less cumbersome (which involves some trial and error with validation)
Acrobat can also create an accessibility report, which I am attaching.
Many thanks for that, it would be great to have something like that when all main issues with accessibility are solved.
the report tells little about the quality Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
