[NTG-context] howto create labels with multiple lines ?

2019-10-10 Thread Floris van Manen
List,

In the metafun-p document, there is the example creating a clock with
labels placed at the dots.

pair destination ;
for whereto = 0 step 30 until 330 :
destination := dir(whereto) * 1.5cm ;
freedotlabel(decimal whereto, destination, origin) ;
drawarrow origin -- destination
withpen pencircle scaled .25mm withcolor .625 red ;
endfor ;


I cannot find any example as how to have a label with multiple lines.
like:

. one
  two


  two
. three
  four


Can someone point me to an example as how to do that?

Thanks
.Floris

[NTG-context] space between headings

2019-10-10 Thread Pablo Rodriguez
Dear list,

I have the following sample:

\showframe\showgrid
\starttext
\section{Section}
\subsection{Subsection}
A sentence.
\section{Section}
Another sentence.
\subsection{Subsection}
Even another sentence.
\stoptext

Is there any way to setup the space after of \section when it is
followed by another heading?

I mean, is there no way to decrease the space between two headings?

Many thanks for your help,

Pablo

Re: [NTG-context] \startitemize + "joinedup" ("nowhite") not working in footnotes?

anyone to confirm/explain/fix the vertical gap?

Hello,

in the following sample there is unwanted vertical gap between text
"Foo" and the first item "- bar" in the footnote 1 (and also between
"Bar" and "- bar") - see red arrows.

The same code used outside the footnote behaves as expected - there is
no vertical space.

Is there anything special about handling itemization inside footnotes?

My code:


\def\T{%
  \startitemize[joinedup,nowhite]
    \item bar
    \item baz
  \stopitemize
}

\def\U{%
  Foo
   \T
  Bar
   \T
}

\starttext
  \U

  \startitemize
    \item Item\footnote{\U}
  \stopitemize
\stoptext


a nasty one ...

add this to cont-new.mkiv

Re: [NTG-context] (bug?) no destinations for footnote links in LMTX

Hi Hans,

I have the following sample:

 \setupinteraction[state=start, focus=standard]
 \starttext

I’m afraid that LMTX doesn’t generate a link to go back from footnote.
All I can see is that MkIV generates two named destinations:

 <<
   /D [ 5 0 R /XYZ 61.65861 129.0214 null ]
 >>
 <<
   /D [ 5 0 R /XYZ 76.72182 722.72927 null ]

But I’m afraid that LMTX generates only one:

 <<

Many thanks for your help,

something in the engine ... pretty old and border case ... will fix it

Re: [NTG-context] Problem inserting image within MP

Taco has already answered the question, but if you just want to insert the 
image as a background, there is no need to do so via MP. The following 
also works:


\setupexternalfigures[location={local,global,default}]
\setupbackgrounds[page][background={Bkg}]

\defineoverlay[Bkg][{\externalfigure[hacker.png][width=\overlaywidth,
height=\overlayheight]}]

\starttext

[NTG-context] Problem inserting image within MP

2019-10-10 Thread context

Hello,

this is a probably basic question, but the following code doesn't 
compile:



\setupbackgrounds[page][background={Bkg}]

\defineoverlay[Bkg][\useMPgraphic{Bkg}]

\startuseMPgraphic{Bkg}
  externalfigure "hacker.png";
\stopuseMPgraphic

\starttext
  Ahoj
\stoptext


with:

"

picture

! Isolated expression.

;
<*>  externalfigure "hacker.png";
;
I couldn't find an `=' or `:=' after the
expression that is shown above this error message,
so I guess I'll just ignore it and carry on.
"

I just want to insert a picture from within MP code. What am I doing 
wrong?


Best regards,

Lukas
