Re: [NTG-context] replacement for \getcitedata

[Michael Eidenbenz]

thanks.
but i'm encountering my old problem:

\externalfigure[\cite[file][Eidenbenz2016]]

gives me an error.
Do I need a lua approach here?

Adding \usecolors[xwi] to the example does not change anything.  Looking
at base/colo-imp-xwi.mkiv revealed, that it does not alter the way
colors are defined, but just defines a huge bunch of additional ones.

I'm very sorry for the confusion.  What I did was to adjust ConTeXt's
gray to have the same grayscale value as the tikzgray.  As is shown
below, the redefinition of gray does not propagate to TikZ.

In pgfutil-context.def there is though

\let\pgfutil@registergray \pgf@context@registergray

So it seems as if gray *should* be propagated from ConTeXt to TikZ,
which apparently takes place when loading TikZ.  Moving
\definecolor[gray][s=0.5] before \usemodule[tikz] shows this behavior.

The question is how to keep colors from ConTeXt and TikZ in sync.

Cheers,
Henri

 I have no clue what you mean.

 \definecolor[red][g=1]

 \startTEXpage
 \starttikzpicture
\fill[red] (0,0) circle (1cm);
 \stoptikzpicture
 \stopTEXpage

 works ok here and gives green. So, one can collect a list of colors
 defined in tikz in a colo-imp-tikz.mkiv and load that one if needed.

Dear Aditya and Hans,

As Aditya pointed out, these (probably used for tracing) colors are 
defined in such a way that they don't go via the context resolver. As 
these (few) colors are basically x windows colors, you can start your 
document with:


\usecolors[xwi]

which will set the context colors differently.


\usemodule[tikz]
\starttext

% Original gray
\blackrule[color=gray,width=1cm,height=1pt]

\starttikzpicture
  \draw[gray,line width=1pt] (0,0) -- (1,0);
\stoptikzpicture

% New colors
\definecolor[gray][s=0.5]
\unprotect
\pgfutil@definecolor{tikzgray}{gray}{0.5}
\protect

% Now ConTeXt's gray = tikzgray
\blackrule[color=gray,width=1cm,height=1pt]


How is that supposed to work? Context will not inherit colors from tikz, 
the most you can expect is the reverse: tikz using context color 
definitions.



\starttikzpicture
  \draw[tikzgray,line width=1pt] (0,0) -- (1,0);
\stoptikzpicture

% Inside TikZ gray is still off
\starttikzpicture
  \draw[gray,line width=1pt] (0,0) -- (1,0);
\stoptikzpicture

\stoptext

normally you want the same colors in tikz images as in context so then

However, without such redefinitions, tikz does not understand ConTeXt

If I add


\csname pgfutil@definecolor\endcsname{gray}{gray}{0.5}


to my document the gray shows up fine.  So that's for sure a feasible
workaround.

Can you comment on the phrase »no need for x colors (users can load it

there exists a proper solution to my color problem.


normally you want the same colors in tikz images as in context so then
defining them in tikz is creating incompatibilities (your case is the
reverse and a-typical)


However, without such redefinitions, tikz does not understand ConTeXt
colors. I use a similar workaround in my documents as well.


I have no clue what you mean.

\definecolor[red][g=1]

\startTEXpage
\starttikzpicture
   \fill[red] (0,0) circle (1cm);
\stoptikzpicture
\stopTEXpage

works ok here and gives green. So, one can collect a list of colors 
defined in tikz in a colo-imp-tikz.mkiv and load that one if needed.


I guess it is a bug with pgfplots rather than tikz (which also means that 
it may be easier to pursuade pgfplot maintainers to use low level tikz 
interface, since tikz is already playing nice with context).


\usemodule[tikz,pgfplots]
\definecolor[red][g=1]

\startmode[bug]
\unprotect
\pgfutil@definecolor{red}   {rgb} {0,1,0}
\protect
\stopmode

Perhaps, one could define a macro `\enabletikzcolors[...list..]` that
will do the appropriate translations.

[NTG-context] different default size when imposing documents

[Pablo Rodriguez]

Hans,

after enabling image scaling in \insertpages
(https://mailman.ntg.nl/pipermail/ntg-context/2016/086114.html), I’m
afraid that the default value and compatibility in imposition is broken.

The minimal sample is the following:

\setuppapersize [A5][A4,landscape]
\setuparranging [2UP]
\setuplayout
  [backspace=0pt,
topspace=0pt,
   width=middle,
  height=middle,
location=middle,
  header=0pt,
  footer=0pt]
\setupinteraction[state=start]
\setupinteractionscreen[option={landscape, paper}]
\starttext
\insertpages[whichever-document.pdf][width=0pt]
\stoptext

Would it be possible to restore the width value to its previous default?

Many thanks for your help,

Pablo

Dear list,

I wanted to draw some nice pictures using TikZ and pgfplots, but then I

Attached you find the output of the ConTeXt example and you can see that
the color of the upper line (the one produced with TikZ inside ConTeXt)
has a much brighter color than the one produced with plain TeX.

I'm using ConTeXt MkIV distributed with TL 2016.

How can I adjust the colors in ConTeXt to match the ones produced by
plain TeX?  I need the adjustment in that direction, because I also have
old images produced with plain TeX/LaTeX that I'd like to seamlessly
integrate in my ConTeXt documents.


you need to figure out the default definitions in tikz then (i suppose 
'help lines' is related to some color)

[NTG-context] Different colors in LaTeX and ConTeXt

[Henri Menke]

Dear list,

I wanted to draw some nice pictures using TikZ and pgfplots, but then I
noticed that the colors of the ticks in my pgfplots graph were unusually
bright and it looked very weird.   So I set up a test

> \usemodule[tikz]
> \starttext
> \starttikzpicture
>   \draw[help lines,very thick] (0,0) -- (1,0);
> \stoptikzpicture
> 
> \externalfigure[test-crop]
> \stoptext

where I produced test-crop.pdf from the following plain TeX sample,
which I also typeset with LuaTeX 0.95 (to make sure it's not a LuaTeX
regression).

> \input luatex85.sty
> \input tikz
> \tikzpicture
>   \draw[help lines,very thick] (0,0) -- (1,0);
> \endtikzpicture
> \bye

Attached you find the output of the ConTeXt example and you can see that
the color of the upper line (the one produced with TikZ inside ConTeXt)
has a much brighter color than the one produced with plain TeX.

I'm using ConTeXt MkIV distributed with TL 2016.

How can I adjust the colors in ConTeXt to match the ones produced by
plain TeX?  I need the adjustment in that direction, because I also have
old images produced with plain TeX/LaTeX that I'd like to seamlessly
integrate in my ConTeXt documents.

Cheers,
Henri
