[NTG-context] Question to a formular

[Ursula Hermann]

Dear list,


I have this formular, but no idea , how to write it in Context. This is a 
formular  with  factorial.


0! := 1
(n + 1)! := (n + 1) n!

Can someone help me please?

Many thanks

Uschi

[NTG-context] Question about drawing flowchart using chart module

[Jeong Dal via ntg-context]

Dear all,

I tried to draw a flow chart using the module[chart].
Following the examples, I draw one.

The problem is that the size of the chart is not changed even though I changed 
the numbers dx,dy, width, height, and maxwidth in the \setupFLOWcharts

Please tell me how to resize the chart.

Thank you.

Dalyoung

Hi Michal,

many thanks for your reply.

Your code fixes the "auto" option. At least with the following sample:

  \setupinteraction[state=start]
  \unexpanded\def\IncludeVideo[#1]
   {\definerenderingwindow[#1]
  [width=\textwidth, height=\textwidth,
  framecolor=red]
\userendering[#1][video/mp4][#1]
  [embed=yes, auto]
\placerenderingwindow[#1][#1]}
  \starttext
  \null\page
  \startTEXpage[offset=1em, pagestate=start]
\IncludeVideo[video-1.mp4]
  \stopTEXpage
  \null\page
  \startTEXpage[offset=1em, pagestate=start]
\IncludeVideo[video-2.mp4]
  \stopTEXpage
  \null\page
  \stoptext

I attach a diff and complete file with the the fix from today and the
addition of controls, volume, repeat and opacity you sent me some days
ago (already sent in
https://mailman.ntg.nl/pipermail/dev-context/2022/003957.html).

Just in case Hans may review your code and merge into ConTeXt.

AFAICT I based the auto option on the "Start/StopCurrentRendering"
actions (2021-09-14) which we later agreed to remove (2021-09-17), so
there was a bug. Reasoning for removal of the "Current" variants at the
time:

So Start/StopRendering{label} should be used instead (Hans already redid
most of the examples, you found the two places in scrn-wid.mklx where
there is an incosistency.

I would think that something like the attached could work. But in some
cases it fails on the TeX side with something I am not sure about. I
probably overlooked something. Anyways the idea is to just use the
Start/StopRendering actions with the correct label.

[NTG-context] question about multimedia renderings

[Pablo Rodriguez via ntg-context]

Dear list,

I’m planning to add an explanation about multimedia inclusion to the
wiki, but first I wanted to discuss an issue I have found.

I have the following sample (adapted from scrn-wid.mklx):

  \setupinteraction[state=start]
  \starttext
  \null\page
  \definerenderingwindow[myrenderingwindow]
[width=\textwidth, height=\textwidth,
 %openpageaction=StartCurrentRendering,
 %closepageaction=StopCurrentRendering,
 openpageaction=StartRendering{\currentrendering},
 closepageaction=StopRendering{\currentrendering},
 framecolor=red]
  \startTEXpage[offset=1em, pagestate=start]
  \userendering[key-name][video/mp4][video.mp4]
[embed=yes,
 auto,
 ]
  \placerenderingwindow[myrenderingwindow][key-name]
  \stopTEXpage
  \null\page
  \stoptext

\userendering[][][auto] would enable automatic play or stop when the
page with the rendering is reached or left (respectively).

I cannot get it working. Neither do work the commented lines in
\definerenderingwindow.

Inspecting the PDF code, the screen annotation only gets an additional
actions dictionary
(https://opensource.adobe.com/dc-acrobat-sdk-docs/standards/pdfstandards/pdf/PDF32000_2008.pdf#G11.2096829)
with /PO and /PC entries, when open and close page actions are set to
StartRendering{\currentrendering} and StopRendering{\currentrendering}.

Just for reference, this is the screen annotation object with the
additional actions dictionary:

  13 0 obj
  <<
/Type /Annot
/A <<
  /AN 13 0 R
  /OP 0
  /R 12 0 R
  /S /Rendition
>>
/AA <<
  /PC <<
/AN 13 0 R
/OP 1
/R 12 0 R
/S /Rendition
  >>
  /PO <<
/AN 13 0 R
/OP 0
/R 12 0 R
/S /Rendition
  >>
>>
/Border [ 0 0 0 ]
/P 14 0 R
/Subtype /Screen
/T 
/Rect [ 12.353668 12.353668 437.54664 437.54664 ]
  >>
  endobj

And this is what I get with \userendering[][][auto]:

  13 0 obj
  <<
/Type /Annot
/A <<
  /AN 13 0 R
  /OP 0
  /R 12 0 R
  /S /Rendition
>>
/Border [ 0 0 0 ]
/P 14 0 R
/Subtype /Screen
/T 
/Rect [ 12.353668 12.353668 437.54664 437.54664 ]
  >>
  endobj

Could anyone be so kind to confirm the issue?

Many thanks for your help,

Pablo

[NTG-context] Question about text backgrounds

[Alexandre Christe via ntg-context]

Hi,

I just came across nofmultipars (which is great for splitting frames across
pages, unlike a simple framed). Is there an equivalent for floats?

The MWE would contain

\startuseMPgraphic{mp:textFrame}
begingroup;
path p ;
for i = 1 upto nofmultipars :
p := (ulcorner multipars[i]) -- (llcorner multipars[i]) -- (llcorner
multipars[i] xshifted .25cm) -- (ulcorner multipars[i] xshifted .25cm) --
cycle ;
fill p withcolor "darkgreen" ;
endfor;
endgroup;
\stopuseMPgraphic

together with

\definetextbackground
[exampleFrame]
[
mp=mp:textFrame,
location=paragraph,
]

Assuming I have between \starttextbackground[exampleFrame] and
\starttextbackground[exampleFrame] also a figure in addition to text
paragraphs. Would it be possible to also draw a rule next to it?

Best regards,
Alex

[NTG-context] Question to footnote settings

[Tomáš Hála via ntg-context]

Hi all,
I am struggling with the width of a footnote number area. I would like to ask 
how can I set it dynamically based on the width of the largest number on a 
given page.

Without width I get two different footnote texts widths (compare #9+10).
With width there is a redundant space on the left (see p. 1).
(Number alignment to the right is required.)

Thanks in advance for some hints.

Tomáš

It is simply wrong to say that \italicface as defined gives only \it or \bi as 
a result. Look at the definition. If the current fontalternative is it \it it 
will give a \tf result. It is sensitive to the current state in a similar way 
that \em and \emph are, but it will always give an italic or roman result.


If we leave the comparisons between \em and \italicface aside and talk only 
about the results from \italicface we have a common ground.

You're right the results from \italicface aren't predictable and a fix is 
needed but the same applies also to \boldface, \slantedface and \typeface.

Attached is the output from a modified version of the styling command (the \sc 
column is the fallback style). \swapface is unchanged and I'm not sure about 
its output because it uses the \em code for italic and slanted which means 
\setupbodyfontenvironment[default][em=blue] affects also the \swapface results.

Thank you very much for attacking and clarifying this! It confused me from the 
beginning...


Just a short update on the topic. The following four font switches 
result now in predictable output (e.g. \typeface produces always upright 
text which is either \tf or \bf):


    - \typeface
    - \italicface
    - \slantedface
    - \boldface

fontalternative is it \it it will give a \tf result. It is sensitive 
to the current state in a similar way that \em and \emph are, but it 
will always give an italic or roman result.




If we leave the comparisons between \em and \italicface aside and talk 
only about the results from \italicface we have a common ground.


You're right the results from \italicface aren't predictable and a fix 
is needed but the same applies also to \boldface, \slantedface and 
\typeface.


Attached is the output from a modified version of the styling command 
(the \sc column is the fallback style). \swapface is unchanged and I'm 
not sure about its output because it uses the \em code for italic and 
slanted which means \setupbodyfontenvironment[default][em=blue] affects 
also the \swapface results.

The \italicface command uses either \it or \bi as result but it never

there are commands (e.g. \boldface) with similar results. To get a 
slanted style you have to use the \slantedface command.

Hello list mavens,

What are the circumstances under which style=italicface should be 
used instead of style=italic. I note a difference when I define 
highlighting. I expected to see no difference in the line before and 
line after the hairline the example below, but see that italicface 
adapts to nesting, while italic does not:


Are there other places where this makes a difference?

\setupbodyfontenvironment
        [default]
    [em=italicface] %same with italic for this example
\definehighlight
    [emIt]
    [style=italic]
\definehighlight
    [emIf]
    [style=italicface]
\definehighlight
    [emEm]
    [style=\em]

\starttext

{\em abc {\em def} ghi}: \type{\em}

\emph{abc {\emph def} ghi}: \type{\emph}

\emEm{abc {\emEm def} ghi}: \type{\emEm \definehighlight[style=\em]}

\emIf{abc {\emIf def} ghi}: \type{\emIf
\definehighlight[style=italicface]}

\hairline

\emIt{abc {\emIt def} ghi}: \type{\emIt
\definehighlight[style=italic]}

\stoptext



The \em command has two special values which are allowed when you 
change the style with


    \setupbodyfontenvironment[default][em=...]

with the value "slanted" and "italic". When you choose one of them 
the result depends on the current weight (\tf or \bf) but with every 
other value you're just using whatever the style command/name provides.



When you pass "italicface" you're using a style which uses either \it 
or \bi dependant on the current weight. The result from the "italic" 
value doesn't depend on the behavior or the normal italic style (\it) 
which is the reason why you get different result when you use \em 
compared with \it.



Example:

\starttext

\tex{it}: normal {\it italic} {\bf bold {\it italic}}

\tex{italicface}: normal {\italicface italic} {\bf bold {\italicface 
italic}}


\tex{em}: normal {\em italic} {\bf bold {\em italic}}

\stoptext


Wolfgang 



Wolfgang,

I understand that mechanism, but I am asking a different question, I 
think.


When we specify style=\em or style=italic (and most examples I see use 
the later) in a setup of some sort, I think most folks expect similar 
behavior, but clearly it is not because italic does not track changes 
in emphasis. However, style=italicface does seem to match the behavior 
of style=\em (mostly, see the bug report below).




The basic font commands are \tf, \it, \sl, \bf, \bs and \bi and when you 
want for example bold italic text you always have to use \bi even the 
current text is already bold because \it produces normal italic text.


\em is a special case because it affects also italic text:

\starttext

\startlines
\tf normal {\em emphasized}
\sl slanted {\em emphasized}
\it italic {\em emphasized}
\bf bold {\em emphasized}
\bs bold slanted {\em emphasized}
\bi bold italic {\em emphasized}
\stoplines

\stoptext

So, I am asking whether, in places where folks often use style=italic, 
it might be better to consider style=italicface.


Bug report: \meaning\italicface gives:

protected macro:\relax \ifx \fontalternative \s!tf \it \orelse
\ifx \fontalternative
\s!bf \bi \else \tf \fi

This leaves out the transition from bi to bf. That transition is done 
by \emph, but \emph may give slanted while \italicface is always italic.




The \italicface command uses either \it or \bi as result but it never

Hans is working on a new mechanism and has recently been thinking about 
integrating (some of) the functionality of this module. As far as I remember, 
it was mkii. (And I was the one who pushed Hans to do work on it, but could 
never really come up with a reasonable interface and
specifications.) So I would say yes, it is more or less obsolete; I wouldn't 
start a project with it.

Hans is working on a new mechanism and has recently been thinking about 
integrating (some of) the functionality of this module. As far as I 
remember, it was mkii. (And I was the one who pushed Hans to do work on 
it, but could never really come up with a reasonable interface and 
specifications.) So I would say yes, it is more or less obsolete; I 
wouldn't start a project with it.

Hi Gerben,

Not behind a computer right now, but you should look at the output of

You were (attempting to) redefine the macro’s arguments, but they are read-only.

A somewhat longer answer: the type of macro arguments in this case is “expr”. 
Metapost argument types are based solely on what the internal language parser 
needs to interpret the code; the language is not strongly typed.

Also, during macro expansion, your code is replaced by:

  %numeric (READONLY TEMP VALUE 1);
  %numeric (READONLY TEMP VALUE 2);
  draw unitsquare scaled 10 xshifted (READONLY TEMP VALUE 1);
  draw unitsquare scaled 10 yshifted (READONLY TEMP VALUE 2);

Taco

Re: [NTG-context] question about vardef variables

[Jeong Dal]

Dear Damien Thiriet,

If you change ‘vardef’ to ‘def’, you will get the figure.
There is a difference between ‘vardef’ and ‘def’.
AFAIK, vardef returns the value of the last statement in the macro.
Please see  the examples in Metafun manual from page 32 ~ .
I hope that you find your answer there.

I am sorry that I am not good enough to explain the variables.

Best regards,

Dalyoung

[NTG-context] question about vardef variables

[Damien Thiriet]

Hi,


I have some troubles with understanding metafun's macro mechanism.

Given this MWE:

\starttext
\startMPpage

vardef Test (expr ab,cd)=
   %numeric ab;
   %numeric cd;
   draw unitsquare scaled 10 xshifted ab;
   draw unitsquare scaled 10 yshifted cd;
enddef;

Test (50,100);
\stopMPpage
\stoptext

Uncommenting the two declarations makes me run intro a silent error. I was 
lucky enough yesterday to get an explicit error message with a more 
complex macro.  It made me figure out where my problems came from.

So here are my two questions:
- Why shouldn't we tell metafun if expr is a path, a pair or so on?
- Would it be possible to issue an error message each time this wrong
declaration is made?

Thanks,


Damien Thiriet

This is the first time I see \offinterlineskip. Thanks to “TeX for the

I wonder whether arranging is a more proper way of doing labels.

Maybe I’m too lazy, but I see this variant also as a more complex way to
achieve it.

Many thanks for your reply, Hraban.

I’m afraid that offset is related to the space between frame and its
content.

Or at least, I couldn’t make it work.

Nope. But this contains the key to the solution.

\blank[-0.395mm] corrects the extra vertical space between frames in
this case.

[NTG-context] question on page transitions

[Pablo Rodriguez]

Dear list,

I have a question about page transitions (lines 297-304 from scrn-pag.mkvi):

\def\scrn_transitions_set_indeed
  {\begingroup
   \edef\currentinteractionscreendelay{\interactionscreenparameter\c!delay}%
   \clf_setpagetransition
  n {\scrn_transitions_list}%
  delay \ifx\currentinteractionscreendelay\v!none
\zerocount\else\currentinteractionscreendelay\fi
   \relax
   \endgroup}

I wonder whether the "delay" option in \setupinteractionscreen defines
the number of seconds for the page or for the transition.

From what I read in the code above, I would say that the duration is
defined for the  transition itself.

Inspecting the output PDF code in generated documents, the duration is
set for the page.

In PDF code. /Page <> sets the number of seconds for the
page
(https://www.adobe.com/content/dam/acom/en/devnet/pdf/PDF32000_2008.pdf#search=duration).

/Page <> >> sets the number of seconds for the transition
(https://www.adobe.com/content/dam/acom/en/devnet/pdf/PDF32000_2008.pdf#nameddest=G11.2295795).

With the followling sample:

\setuppapersize[A9,landscape]
\setupinteraction[state=start]
\setupinteractionscreen[option=max, delay=5]
\setuppagetransitions[random]
\setupbodyfont[50pt]
\starttext
\dorecurse{2}{%
  \startmakeup[page][style=\bf\ss, align=center]
\recurselevel
  \stopmakeup%
  }
\stoptext

The output PDF document may contain a /Page object such as:

6 0 obj
<<
  /Contents 4 0 R
  /Dur 5
  /Trans <<
/Di 90
/M /O
/S /Fly
  >>
  /Type /Page
>>
endobj

This forces the viewer to advance the page after 5s. To have a
transition duration of 5s, it should read:

6 0 obj
<<
  /Contents 4 0 R
  /Trans <<
/D 5
/Di 90
/M /O
/S /Fly
  >>
  /Type /Page
>>
endobj

https://www.adobe.com/content/dam/acom/en/devnet/pdf/PDF32000_2008.pdf#nameddest=G11.2104292
shows the difference between /Dur and /D.

Could anyone confirm whether this should be fixed (or I’m missing
something)?

Many thanks for your help,

Pablo

Yeah, it seems so. I'm much more afraid of getting Arabic and Judeo-Arabic 
right...

Well, it's not field tested yet. But yes, the demo files work.

Yeah, as always, the output is only as good as the input. That's partly why I 
use pandoc (twice, actually.) In a first run, I produce a normalized markdown 
file, where such idiosyncrasies are removed. There, I then add additional 
formatting. In the second run I can then produce the XML. We need the XML to 
produce a nice web view using the Lens Viewer. And also, with pandoc it's much 
easier to produce XML than ConTeXt.

Denis

I’m using a Python script to convert DOCX to ConTeXt. The better the input, the 
better the output can be. Usually there’s a lot of manual work. (Last week I 
had an article whose author never grew out of the typewriter, i.e. every line 
was a paragraph, footnotes were just paragraphs at the end of his pages – of 
course my script couldn’t handle that well.)

Even LaTeX is a niche; there are not enough users of ConTeXt for it to look 
reliable, I guess. You can’t really use it without involving yourself in the 
community.

And while I generally love working with ConTeXt, I’m cursing it often enough 
for unexpected/undocumented behaviour, unfinished features and scattered 
documentation. My book is intended to fix the latter, but there’s no progress – 
I got too many different projects and severe limitations of working capacity. 
And children at home...

I will use ConTeXt to typeset the Jewish Studies journal *Judaica* 
(https://bop.unibe.ch/index.php/judaica/index). (The first issue should appear 
soon.) However, we do not accept ConTeXt sources as we use jats xml as our

Yes, I gave two talks last year at the Public Knowledge Project Conference in

IRCPS’s journals are typeset with ConTeXt.
https://ircps.org

Also, our (Verlag Dreiviertelhaus) publications are mostly typeset with 
ConTeXt, including the magazine on German literature, Kritische Ausgabe.

Hi 
Jet a completely different question just out of curiosity?

1) Does anybody know of any scientific publisher or single journals
which accept papers/book chapters typeset in ConTeXt yet
2) If there are any is any of them convinced enought about ConTeXt to
recommend use of ConTeXt or even provide template?
3) What would be needed and what could help to make them aware?

\scale[width=100mm, hwight=100mm]{\clip[width=150mm, height=120mm,
hoffset=30mm, voffset=40mm]{\externalfigure[drawing.pdf]}} % incorrect

\scale[width=100mm, hwight=100mm]{\clip[width=150mm, height=120mm,
hoffset=30mm, voffset=136mm]{\externalfigure[drawing.pdf]}} % correct
\stoptext

I noticed that the voffset parameter *always* counts from the top/left
of the external source. Also if the source has its origin defined at the
lower/left corner.
Is that intentional?

It is confusing as when i place a rectangle on top of the clip i want to
extract from the source pdf, the x,w,w,h of that rectangle will not
match the parameter needed for the \clip command.

Or does there happen to be some snazzy tool out there to get the
coordinates of embedden images within a pdf?

Can you be more concrete what you try to achieve. Do want different 
colors for the borders or just two rules with different colors, the 
first can be achieved with a background graphics while the second can be 
done with the \blackrule command.

Thank you.

It could help but unfornately in the given case it does not suit to 
other (natural) tables which are designed by hrules.

I am looking forward to the future option.

I also do not know how to deal with the distance between the text and the

nothing. What am I doing wrong?

You are right, Hans.

fonts.handlers.otf.addfeature {
name = "stest",
type = "single",
data = {
a = { -500, 0, -500, 0 },

Sorry, but I forgot to consider the test suite.

[NTG-context] question about a ligature

But I have a problem with the following sample:

\startluacode
fonts.handlers.otf.addfeature {
name = "linearb",
type = "ligature",
data = {
C  = { "d", "w", "e" },
Y = { "d", "a" },
b = { "P", "Q" },
}
}
\stopluacode
\definefontfeature[default][default][linearb=yes]

\definefallbackfamily
[mainface]
[rm]
[Noto Sans Linear B]
[range={linearbideograms, linearbsyllabary}]

\definefontfamily
[mainface]
[rm]
[Noto Sans]

\setupbodyfont[mainface]

\starttext
\startTEXpage
da dwe PQ C

What am I missing to get the "dwe" ligature?

 There’s also

 \startnotmode[some]
 This is not typeset in "some" mode.
 \stopnotmode

Fabrice,

there is some misunderstanding. The code from 

Re: [NTG-context] Question on enabling/disabling modes

[Fabrice Couvreur]

Hi Mikael,
I suppose the files test1 and test2 have a special structure ?

%%% file.tex
\doifnotmode{test1}{\enablemode[test1,test2]}
\starttext
\startmode[test1,all]
We are in mode test1.
\stopmode
\startmode[test2,all]
We are in mode test2.
\stopmode
\stoptext
%%%

%%% test1.tex

%%%

%%% test2.tex
???
%%%

Fabrice,

Taco's example is complete. Try

context file.tex
context --mode=test1 file.tex
context --mode=all file.tex

and you will get, in turn, nothing, the content in mode test1, everything.

Thank you, Taco!

I have around 25 of them, and your solution with "all" works indeed well
for me.

This is what I would do if the list of modes is small:

\doifnotmode{test1}{\enablemode[test1,test2]}

(and don’t use the \definemode lines)

But if you need many of them, that could get problematic with
many nested \doifmodeelse statements. 

In that case, I would use a separate ‘all’ mode, and call the
context script with that as argument in the generic case.


%%% file.tex
\starttext
\startmode[test1,all]
We are in mode test1.
\stopmode
\startmode[test2,all]
We are in mode test2.
\stopmode
\stoptext
%%%


Best wishes,
Taco

[NTG-context] Question on enabling/disabling modes

[Mikael P. Sundqvist]

Hi!

I am writing notes for my teaching and would like to do the following with
modes:

* If the file is compiled with context file.tex then everything (i.e. the
content in all modes) is typeset.
* If the file is compiled with context --mode=test1 file.tex then only mode
test1 is typeset.

I do not see how to do this easily. The example I am working on looks like
this:

%%% file.tex
\definemode[test1][keep]
\definemode[test2][keep]
\starttext
\startmode[test1]
We are in mode test1.
\stopmode
\startmode[test2]
We are in mode test2.
\stopmode
\stoptext
%%%

This, however, naturally gives not output, since the modes test1 and test2
are not activated. If I compile with context --mode=test1 file.tex I get
the content in mode test1, as I want.

I have tried to change "keep" to "yes" in the setup of the modes, but then
the material in both modes are typeset no matter what command flag I use.

Do I miss something?

/Mikael

PS In reality I have about 25 lectures, so using this method there will be
about 25 modes in total.

Yes it is wrong. Correct hyphenation points are 

Rind-fleisch-e-ti-ket-tie-rung

That's difficult to do right with patterns, in latex it is isn't
correct either. The problem is that two words have been combined.
(Rindfleisch and Etikettierung).

[NTG-context] question about German hyphenation

[Pablo Rodriguez]

Dear list,

I have the following sample:

\starttext
\de\hyphenatedword{Rindfleisch}
\de\hyphenatedword{Rindfleischetikettierung}
\stoptext

I’m not a native speaker, but I think that "Rindfleisch-etikettierung"
is right in German. (And I think that "Rindflei-schetikettierung" is wrong.)

Are the hyphenation patterns wrong in the cases above, or am I missing
something?

Many thanks for your help,

Pablo

Floating objects or floats exist in many instances. One predefined instance is 
figure and a second is table. So \placelistofINSTANCEs will give you the list. 
You can define more floating objects, for example a sidebox, etc.

The figure and table lists can be combined:

\definecombinedlist [figuresandtables] [figure,table]

\placelistoffiguresandtables

or something like that.

\startcombination [nx=1,ny=2] % my preferred syntax

\stopcombination

allows you to create a combined (matrix) of graphics. It is indeed generally 
used inside a float construct such as \startplacefigure ... \stopplacefigure.


By the way, "alternative=label" is a favorite of mine, making it unnecessary to 
explicitly include labels, as in:

\startcombination [nx=1,ny=2,alternative=label]
  {My top graphic}
  {My bottom graphic}
\stopcombination

rather than

\startcombination [nx=1,ny=2]
  {My top graphic}{a}
  {My bottom graphic} {b}
\stopcombination

[NTG-context] question regarding \placefloats

[Susanne G. Loeber]

Dear Reader,

I have a document with figures and tables. I have tried to use the command
  \placefloats to create a list of all my floats as recommended on the page
Floating Objects, section Flushing floats. There it states: The command
\placefloats outputs all pending floats. I hoped to get a list with all
tables, all figures and all other possible floats.That list would either be
sorted per chapter or sorted per float. However, I was not able to make it
work at all.

In the appendix, you can find my struggles.
First:
\placefloats does not work.

\placelistoffloats does not exist as a command

My solution is two seperate commands, one for the tables \placelistoftables
and one for the figures \completelistoffigures.

Question: how to use \placefloats correctly to get a list of all floats?


Second:

\startcombination[1*2] looks nice, but does not add information to the
\placelistoffigures .

My solution is to place the \startcombination inside a \placefigure.

Question: Is there a better way?


Kind regards, thanks,

Susanne

I don’t understand the question.
A ConTeXt layer is not a PDF layer.
All the objects are manipulatable in Acrobat Pro (or another PDF editor),
there’s no grouping on the PDF level.

If you need PDF layers, there are "viewer layers" in ConTeXt:

\defineviewerlayer[Ebene]
\setupviewerlayer[Ebene][
   state=start,
   visible=no,
   title=Test,
]

\starttext

\startviewerlayer[Ebene]

\stopviewerlayer

More Text

\stoptext

AFAIK completely undocumented, I found them at 
http://source.contextgarden.net/tex/context/base/mkiv/attr-lay.mkiv
while tracking effects/properties (where these were implemented first).

While the example above works, I don’t get viewer layers in my current project, 
must investigate...
And then, if the combination of ConTeXt layers and viewer layers works 
(\setlayer within \start/stopviewerlayer?).


You have to put the viewerlayer command within the the \setlayer argument.

I guess it’s a matter of taste.
Of course calculations are easier in Lua, but in my image placement macros
I struggled a lot with numbers vs. measures/dimensions, regardless if in Lua
or on the TeX level.
