[NTG-context] Making ConTeXt stop on all or some errors

2019-02-03 Thread Jan U. Hasecke
Hi all,

yesterday I asked about where to put color profiles.

My problem was that ConTeXt for some unknown reason didn't find the
color profiles I downloaded. But most annoying was the fact that I
didn't saw the error in the log because ConTeXt only complains about not
finding the profile.

Is there a way to make ConTeXt stop if it does not find the profile like
it stops if I use a unknown command?

I want to avoid that we send a pdf without a profile to the print shop,
because we overlook a message in the logs.

Re: [NTG-context] About the macro path intersectionpoint path with Metapost

2019-02-03 Thread Jeong Dal
Dear Fabrice,

Metapost is great for drawiang figures  but it is not easy for me  to use it.

 A and B are the same point. One of “r” should be changed to “q” or “b”.
Then you can have a line.
I also made similar errors many times too.

Btw, is there any reason to add “—cycle”?

Enjoy the drawing.

Best regards,

Dalyoung

Use the infont operator.  That info is a bit hidden in “2.10 Analyzing

Can you provide a example because the error message shows

Please try to put them to

I solved the problem by installing the color profiles on my debian
machine so that they are in ~/.colors/icc

Then I exported in .bashrc

export OSCOLORDIR="$HOME/.color/icc"

This solved the issue here.

But as I am working in a group I would like to have a solution that
works without installing the color profiles locally.

Use \setupdocument to set the metadata for the PDF. You can access the 
values with the \documentvariable command.

[NTG-context] About the macro path intersectionpoint path with Metapost

2019-02-03 Thread Fabrice Couvreur
Hi,
I would like to reproduce the attached figure. My problem is to create the
points of intersection between the circles. It seems that my approach is
not the right one.
Thank you.
Fabrice

\starttext
\startMPcode
  path p, q, r, b ;
  p:= fullcircle scaled 6cm ;
  q:= fullcircle scaled 4cm shifted (2.5cm,2cm) ;
  r:= fullcircle scaled 4cm shifted (-2.5cm,2cm);
  b:= fullcircle scaled 2cm shifted (0,-3cm);
  pair A, B ;
  A:= p intersectionpoint r ;
  B:= p intersectionpoint r ;
  path u ;
  u:= A--B--cycle ;
  draw p ;
  draw q ;
  draw r ;
  draw b ;
  draw u numberstriped (.25,15,5) withcolor magenta ;
\stopMPcode
\stoptext
