Many thanks for your reply, Peter.

pstoedit uses a very basic PostScript drawing model that isn’t enough
for the vectors I need to convert.

I found the command for the transparency issues:

  \setupcolors[pagecolormodel=auto]

At least, veraPDF doesn’t complain anymore.

Only color profiles for external figures have to be solved.

Many thanks for your help,

Pablo

Many thanks for your reply, Hraban.

I’m afraid that only gs adds the profile without converting the vectors
to bitmaps.

Enjoy the book fair,

Many thanks for the reply, Hans.

I understand the problem now with fragile hacks. Sorry for having
insisted in my proposal.

I fixed the external PDF figure (http://pdf.ousia.tk/icc-vector.pdf) and
I used with in the following sample:

\setupbackend
  [format=PDF/A-3a,
   intent=sRGB IEC61966-2.1,
   profile={sRGB.icc,default_gray.icc},
   level=0]

\setuptagging[state=start]

\setupcolors[cmyk=no, pagecolormodel=auto]

\startTEXpage[offset=1em]
\externalfigure[icc-vector.pdf]
\stopTEXpage
\stoptext

http://pdf.ousia.tk/icc-vector.pdf is the same graphic as
http://pdf.ousia.tk/basic-figures.pdf, but with an ICC profile. The
veraPDF validator (http://verapdf.org) says it’s a valid PDF/A-1b document.

But the output from the sample above
(http://pdf.ousia.tk/xobject-noicc.pdf) isn’t a valid PDF/A document.
The external figure has no ICC profile.

The uncompressed PDF document reveals that the XObject has no reference
to any ICC profile.

I’m afraid this might be a bug.

Many thanks for your help,

Pablo

Just a hint:

pstoedit seems to be incompatible (uses a deprecated option) with the
actual gs (v9.22). I tested it with v9.18 and all worked fine. Of course
the transparency was removed in the process of the eps export. Not a
real problem with the metapost code at hand.

pstoedit -v -ssp -f "mpost:" transparent.eps transparent.mp

Tested on Windows 10 (1703), Inkscape v0.92.2, gs v9.18, pstoedit v3.70;
all 64bit

I use git. But on two Computer there are always some settings that
you don't want to share e.g. on the one texlive is in D:\texlive and
on the other in C:\users\...\texlive. And the relative pathes
between context and texlive are different too.

The tricky part is to fit it in my current configuration system. I
share configuration between two PC and so adding things which should
have an effect only on one of them needs (due to different pathes)
always a bit thinking -- not impossible and not so difficult but a
bit tricky ;-). So adjusting a local file would be easier.

Hm, I’m used to setup/make scripts per project, setting some path works well
