Hi,
I uploaded a beta. Peter Rolf and I have spent quite some time on pdfx
related issues (mostly trying to figure out the right specs and how to
deal with them). We started with a command driven interface but
eventually it ended up with a single command:
\setupbackend
[format=PDF/X-3:2002,
intent=sRGB]
Lookups are case insensitive. The intent can be a comma separated list
of profiles. The name is resolved using colo-icc.xml (or color-icc.lua)
but one can also pass a (list of) files using the 'file' key. You can
check handling with:
\enabletrackers[backend.pdfx]
When choosing a format, color spaces, transparency and layers are
automatically disabled in the backend code but they do function in the
frontend. Of course included images are the user's responsibility but
color etc in MP graphics should work out ok.
There are probably rough edges.
