Many thanks for your reply, Luigi.

The real graphic is a vector logo and I need to keep it as a vector
image. I converted it from a SVG source into a PDF document (years ago).

I cannot remember if the vector image contains transparency. If needed,
I would remove it from the image.

The way to convert it may be using Inkscape into a PostScript document
and then to MetaPost using pstoedit (as I have just discovered).

Is that right or could something get lost in the translation?

Many thanks for your help,

Pablo

[NTG-context] issue with external image and PDF/A-3a

2017-10-05 Thread Pablo Rodriguez 
Dear list,

I have this minimal 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]

\startTEXpage[offset=1em]
\externalfigure[transparent]
\stopTEXpage
\stoptext

The external figure is available from
http://pdf.ousia.tk/transparent.pdf (and output file at
http://pdf.ousia.tk/transparent-pdf-a-3a.pdf).

Using veraPDF (http://verapdf.org/), the output document doesn’t comply
with the validation profile requirements.

As Luigi wisely predicted, external images may be problematic.

I get one error, because of the color of the external figure:
https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-and-3-rules#rule-6243-2.

The PDF object in question is the following:

12 0 obj
<<
  /Type /XObject
  /Subtype /Form
  /FormType 1
  /BBox [ 0 0 316.896 215.5669 ]
  /Group <<
/Type /Group

0.188235 0.392157 0 rg /a0 gs
28.348 187.219 260.203 -158.871 re f
Q
endstream
endobj

Well, this is a minimal sample, but my real document is much bigger. Is
there any way to convert the stream to something that ConTeXt can handle
directly?

Many thanks for your help,

Pablo

I have glfw-3.2.1 in my Fedora 25 machine and it works fine.

Just in case it might help,

[NTG-context] Another question to structured trees for linguistics

2017-10-05 Thread Ursula Hermann 
Hi everybody!

 

I have another question to this thread: if I need a structured tree  for
lingustics, i mean a structured tree with senteces, can I use also mp-trees?

 

I ask, because at Ctan I found a package called "qtrees". So in this package
ist called \Tree and then there comes the following: [.S This [.VP [.V is
]\roof{a simple tree}.NP ] ] for example . Or how would I write it in
metapost?

 

Can somebody help me?
