[NTG-context] floats disturb grid setting
As soon as I use floats, text isn’t typeset on the grid any more:

[NTG-context] remote images
Hi, fetching images per URI was supported (and is also documented in the wiki), but with LMTX 2022.09.11 and one of \externalfigure[http://tug.org/images/logobw.jpg] or \externalfigure[https://picsum.photos/300/200] I only get the usual grey box. No error message. Do I need any setup, was this discarded in LMTX, or what’s wrong?

[NTG-context] ConTeXt meeting and the annotated cow
Hello, last week I learned something about MetaPost at the context meeting. Thanks Taco! First a little background: I write a lot of documentation and sometimes I need to include a picture with annotations. Until now I used a drawing program to add text and arrows. This has one disadvantage, these annotations are not translated. I have to prepare a set of pictures for every language. Well, that changed last week. Here is my first try (actually the 4th iteration): %%% \setupexternalfigures[location=default] \starttext \startMPinclusions %draft := 0; draft := 1; color mycolor; if draft = 1 : mycolor := red ; else: mycolor := .4white ; fi ; % Draw a grid to count locations def gridscaled = pair ur; ur = urcorner currentpicture; width := xpart ur; height := ypart ur; xstep := ceiling(width / 10); ystep := ceiling(height / 10); if draft = 1: counter := 1; for i = xstep step xstep until width : draw (i, 0 ) -- (i, height); label.rt(counter, (i , 0.5 cm)); counter := counter + 1 ; endfor; counter := 1; for i = ystep step ystep until height : draw (0, i) -- (width, i); label.top(counter, (0.5 cm, i )); counter := counter + 1 ; endfor; fi; enddef; % Bottom: The annotation is at the bottom of the start point def annotb (expr a, b, c, d) (text t) = label.bot (t, (a * xstep, b * ystep)); drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep) withpen pencircle scaled .8mm withcolor white; drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep) withpen pencircle scaled .5mm withcolor mycolor; enddef ; % Top: The annotation is on top of the start point def annott (expr a, b, c, d) (text t) = label.top (t, (a * xstep, b * ystep)); drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep) withpen pencircle scaled .8mm withcolor white; drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep) withpen pencircle scaled .5mm withcolor mycolor; enddef ; % Right: The annotation is on the right of the start point def annotr (expr a, b, c, d) (text t) = label.rt (t, (a * xstep, b * ystep)); drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep) withpen pencircle scaled .8mm withcolor white; drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep) withpen pencircle scaled .5mm withcolor mycolor; enddef ; % Left: The annotation is on the left of the start point def annotl (expr a, b, c, d) (text t) = label.lft (t, (a * xstep, b * ystep)); drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep) withpen pencircle scaled .8mm withcolor white; drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep) withpen pencircle scaled .5mm withcolor mycolor; enddef ; \stopMPinclusions \startMPpage % Picture draw externalfigure "cow.pdf" xsized 16cm; % Grid gridscaled; % Text annotb (1, 5, .8, 7.3, "Maul"); annotb (6, 2, 7, 3.2, "Euter"); annott (9.2, 9.5, 9.6, 3, "Schwanz"); annotb (3, -.5, 3.1, .9, "Huf"); annotb (3, -.5, 3.9, 1.1, ""); \stopMPpage \startMPpage % Picture draw externalfigure "cow.pdf" xsized 10cm; % Grid gridscaled; % Text annotb (1, 5, .8, 7.3, "Maul"); annotb (6, 2, 7, 3.2, "Euter"); annott (9.2, 9.5, 9.6, 3, "Schwanz"); annotb (3, -.5, 3.1, .9, "Huf"); annotb (3, -.5, 3.9, 1.1, ""); \stopMPpage \stoptext %%% There are still some further ideas and a lot to learn for me: - multi line annotations - a transparent white background - a frame around the text - a link to the section where the part is explained - moving to one command with the orientation as an argument Comments and improvements are welcome.

Re: [NTG-context] setupexternalfigures and resoĺution
Thanks for this code Hraban. I tried this last night and it worked really
well. I did have one stumbling block when I noticed that those image files
with a space in their names were not found, however renaming without a
space solved the problem. Is this a bug or a feature?
Thanks

Hi Aditya,
I wonder whether your final definition should be rewritten as:
\unexpanded\def\includePDF[#1]%
{\getfiguredimensions[#1]
\dorecurse{\noffigurepages}
{\startTEXpage
\externalfigure[#1][page=\recurselevel]
\stopTEXpage}}
At least, otherwise it will only work with "talk.pdf".
Or am I missing something?

Re: [NTG-context] Clipping multiple PDFs
Hello,
Thanks to Pablo and Aditya for the solutions. Sometimes it is very
difficult to find the right manuals and info for what you want to achieve
for those of us new to ConTeXt. I found the stuff on
context(context.noffigurepages) here (
https://wiki.contextgarden.net/Image_Placement) and I didn’t know the
manual you linked to existed. I have also been searching for stuff about
“low-level” stuff in ConTexT like the \doloopoverlist command.
I hope to contribute to the online wiki as I become a better user of
ConTeXt.

The approach is totally different: "getnofpages"
(http://www.pragma-ade.com/general/manuals/luametatex.pdf#search=getnofpages).
BTW, your code crashed my session, CPU goes to 100% and RAM usage too. I
wonder how your sample could be compiled fine by your system.

Re: [NTG-context] Clipping multiple PDFs
Thanks for the solution Pablo. It works well.
I wanted to add more pdfs (which also has many pages) and found it was
easier for me to reason in the lua side of things. This is what I have
at the moment:
\starttext
\startluacode
local function doc(fil)
return fil..[[.pdf]]
end
local function disppdf(fname)
n = 1
repeat
context.externalfigure({fname},{
page = n,
width = "200mm",
scale = "950"
})
n = n + 1
until n == context(context.noffigurepages)
end
local pdffiles = {"ass1", "ass2", "ass3", "ass4", "ass5", "ass6", "ass7",
"ass8"}
for index=1,#pdffiles do
local f = doc(pdffiles[index])
context.getfiguredimensions({f})
disppdf(pdffiles[index])
end
\stopluacode
\stoptext
I didn’t know how to get an array (or indexed table or whatever you call
it) in ConTeXt/Tex. My problem is now with context(context.noffigurepages).
Am I calling it wrong? All I want to do is call \noffigurepages from the
lua side. Is there something I am missing?

Hi Jethro,
it works using \clip with \externalfigure inside a loop (\dorecurse).
With \getfiguredimensions you get the number of pages of each PDF
document (\noffigurepages).
The following source both generates the source PDF document and the

mentioned above):
\startbuffer[newbuff]

\setupbodyfont[sans, 1200pt]

\setuppaper[nx=2, ny=2]
\setuparranging [XY]

[NTG-context] Write a long chapter title in two lines

So, I send the same mail again.
Thank you for reading.

I’d like to write a long chapter title in two lines if it is longer than the

It is OK when I use just bigger fonts.
But it writes the long title in one line if I use outlined font for title as in

Is there a way to write it in two lines using the outlined font?

[NTG-context] sync text streams in facing pages
Dear list,
adapting a the sample from mkxl/page-str.mkxl (and code from the list),
I came with the following sample:
\setuppapersize[A6]
\showgrid
%\setuplayout[grid=yes]
\starttext
\input tufte
\startoutputstream[es]
\dorecurse{25}
{\startlanguage[es]\input cervantes-es\stoplanguage%
\par\pushoutputstream}
\enableoutputstream[en]
\dorecurse{25}
{\input zapf\par\pushoutputstream}
\disableoutputstream
\stopoutputstream
\synchronizestreams[es,en]
\page \flushoutputstream[es]
\page \flushoutputstream[en]
\stoptext
To reorder pages, I rename the output to "wg.pdf" and run the following
code:
\setuppapersize[A6]
\setuplayout[page]
\starttext
\dorecurse{26}
{\ifnum\recurselevel = 1
\externalfigure[wg.pdf][page=\recurselevel]\else
\externalfigure[wg.pdf][page=\recurselevel]
\externalfigure[wg.pdf][page={\the\numexpr \recurselevel + 25}]\fi}
\stoptext
I’m afraid that the paragraph mistmatch is clear (the number of pages is
way different for each versions).
Using the grid, the mismatch is not so evident (but there is still a
different number of pages for each version).
Page reordering would be in this case:
\setuppapersize[A6]
\setuplayout[page]
\starttext
\dorecurse{20}
{\ifnum\recurselevel = 1
\externalfigure[wg.pdf][page=\recurselevel]\else
\externalfigure[wg.pdf][page=\recurselevel]
\externalfigure[wg.pdf][page={\the\numexpr \recurselevel + 19}]\fi}
\stoptext
I would need that for a bilingual edition. I don’t mind reodering the
pages (if there is no other option).
But what am I doing wrong not to get synced text streams for facing pages?
Many thanks for your help,
Pablo

Re: [NTG-context] parameters of (setup)externalfigure, conversions etc.
Am 11.08.22 um 15:51 schrieb Henning Hraban Ramm via ntg-context:
Hi Hans,
yesterday you told me about the image conversions in grph-con.lua, and I
tried to find out how to use them. Up to know I only knew "mp" for SVG
images.
I found I can use "gray.pdf" or "cmyk.pdf" to convert an image (JPG or
PNG) to grayscale/CMYK, but the resolution isn’t used for downsampling
(of course, it’s not mentioned in the command template):
\externalfigure[hacker][conversion={gray.pdf},resolution=72]
I tried to write my own downsampling converter, but don’t understand how
I can hook it into the list of converters:
"""
local downsample = sandbox.registerrunner {
name = "downsample",
program = "gm",
template = [[convert -compress Zip -sampling-factor 1x1 -density
%resolution%x%resolution% -resample %resolution%x%resolution% %oldname%
%newname%]],
checkers = checkers,
defaults = defaults,
}
programs.downsample = { runner = downsample }
I found the solution in
https://wiki.contextgarden.net/Using_Graphics#Image_Conversion, but
that’s not as elegant as those in grph-inc.lua
(And I learned that ImageMagick’s convert works differently than
GraphicsMagick’s WRT -density; i.e. you must use "gm convert".)
Peter Münster’s grph-downsample.lua was better, it calculated the actual
pixel size necessary, but that doesn’t work any more.
"""
(I’m not sure if I must calculate the desired pixel size beforehand.)
-*-*-
Apart from converters, there are several parameters of \externalfigure
that I don’t understand and thus can’t document in the Wiki; a few are
even not yet documented in the interface files:
* equalwidth/equalheight
* s/sx/sy
* xmax/ymax
* prefix, label, comment
* bodyfont
* mask
* frames (≠ frame)
* interaction (PDF inclusion; found)crossreference
* resources
* display (alternative source? multimedia only?)
* order (of extensions; found)
* crop, transform
* controls, preview: only related to video and thus obsolete?
* hfactor/wfactor: When do these make sense? (I know factor)
Also, orientation seems to be missing in the interface (auto-syntax
doesn’t pick it up).

[NTG-context] TIL: figure combinations
You probably know about combinations to place images side by side:
\startcombination[3*1]
{\externalfigure[cow]}{cow}
{\externalfigure[mill]}{mill}
{\externalfigure[hacker]}{hacker}
\stopcombination
Now, the widths aren’t calculated automatically.
You could define them on your own:
\startcombination[3*1]
{\externalfigure[cow] [width=.3\textwidth]}{cow}
{\externalfigure[mill] [width=.3\textwidth]}{mill}
{\externalfigure[hacker][width=.3\textwidth]}{hacker}
\stopcombination
But that’s ugly and tedious. Hans did it for you:
\definemeasure[combination][
(\textwidth
-\effectiveleftskip
-\effectiverightskip
-\numexpr\combinationparameter\nx-\plusone\relax\dimexpr\combinationparameter\distance\relax
)/\combinationparameter]
So you can say:
\startcombination[3*1]
{\externalfigure[cow] [width=\measure{combination}]}{cow}
{\externalfigure[mill] [width=\measure{combination}]}{mill}
{\externalfigure[hacker][width=\measure{combination}]}{hacker}
\stopcombination
But that’s still tedious.
With the power of \defineexternalfigure:
\defineexternalfigure[combination][width=\measure{combination}]
(That’s predefined, no need to copy!)
\startcombination[3*1]
{\externalfigure[cow] [combination]}{cow}
{\externalfigure[mill] [combination]}{mill}
{\externalfigure[hacker][combination]}{hacker}

[NTG-context] parameters of (setup)externalfigure, conversions etc.
Hi Hans,
yesterday you told me about the image conversions in grph-con.lua, and I
tried to find out how to use them. Up to know I only knew "mp" for SVG
images.
I found I can use "gray.pdf" or "cmyk.pdf" to convert an image (JPG or
PNG) to grayscale/CMYK, but the resolution isn’t used for downsampling
(of course, it’s not mentioned in the command template):
\externalfigure[hacker][conversion={gray.pdf},resolution=72]
I tried to write my own downsampling converter, but don’t understand how
I can hook it into the list of converters:
"""
local downsample = sandbox.registerrunner {
name = "downsample",
program = "gm",
template = [[convert -compress Zip -sampling-factor 1x1 -density
%resolution%x%resolution% -resample %resolution%x%resolution% %oldname%
%newname%]],
checkers = checkers,
defaults = defaults,
}
programs.downsample = { runner = downsample }
"""
(I’m not sure if I must calculate the desired pixel size beforehand.)
-*-*-
Apart from converters, there are several parameters of \externalfigure
that I don’t understand and thus can’t document in the Wiki; a few are
even not yet documented in the interface files:
* equalwidth/equalheight
* s/sx/sy
* xmax/ymax
* prefix, label, comment
* bodyfont
* mask
* frames (≠ frame)
* interaction, crossreference
* resources
* display
* order
* crop, transform
* controls, preview: only related to video and thus obsolete?
* hfactor/wfactor: When do these make sense? (I know factor)
I accidentally learned that I can use parameters of \framed, but the
inheritance from \setupframed is not explicit – some are mentioned, like
backgroundcolor, others not, even if they work, like corner (but they
don’t affect the image).

Re: [NTG-context] Cron /var/www/aanhet.net/context/bin/cron/context-mirror
Dear Hans,
Thank you for the new way to align math formulas.
It is great to use “\alignhere”, “\breakhere”.
However, I got a problem today.
If I use it with figures side by side, then the alignment is broken.
Please try the following MWE.
Best regards,
Dalyoung
\setupexternalfigures[location={default,local,global}]
\starttext
\startplacefigure[location=right,]
\externalfigure[cow][width=.3\makeupwidth]
\stopplacefigure
\startformula
U(f,P) \alignhere = f(2,2)\Delta A_{11}+f(2,3)\Delta A_{12}\breakhere
\skiphere[1em] +f(3,2)\Delta A_{21}+f(3,3)\Delta A_{22} \breakhere
= 4\times 2 + 6 \times 1+ 6 \times 2 +9 \times 1 \breakhere
= 35.

It is subtle, but you need:
context.externalfigure({“cow.pdf"},{width="0.5\\textwidth"})
A “lua table” becomes [] stuff, a “lua string” becomes {} stuff. Your original
resulted in
\externalfigure{{cow.pdf}}[width={0.5\textwidth}]

Re: [NTG-context] Set up external figure for particular image type

Thank you, Wolfgang.
That looks promising.
SVG files are converted using MetaPost. I thought the following would
work:
svg=>{\externalfigure[#1][svg][conversion=mp]}
You can probably remove the second argument ([svg]) which was used in my
example to pass the default values with \defineexternalfigure. Just
using \externalfigure[#1][conversion=mp] where you pass the default
values with the second argument is enough.

Re: [NTG-context] Set up external figure for particular image type
Thanks, Rik.
Not using Pandoc. I was using Pandoc up until 2020:
https://dave.autonoma.ca/blog/2019/05/22/typesetting-markdown-part-1/
I've since authored KeenWrite <https://github.com/DaveJarvis/keenwrite>,
which uses flexmark-java <https://github.com/vsch/flexmark-java> to
generate XHTML documents from Markdown. The only additions I've made to the
library is to add support for Pandoc's annotation syntax (:::).
That said, I'm also a firm believer in not duplicating information. The
information (file name extension) is already available in the documents, so
adding a classification on top of the extension feels redundant.
Thanks for the suggestion!

Assuming that Pandoc markdown is being used, you should be able to set
class attributes on each image. You can then associate external figure
definitions with specific classes, and process each individually.

[NTG-context] dorecurse within combination
Hi, I’d like to place pages from a multipage PDF in a combination:
\startcombination[3*1]
\dorecurse{3}{%
{\externalfigure[multipage][width=\textwidth/3,page=\recurselevel]}{}
}
\stopcombination
That doesn’t work, because ConTeXt expects a { after \startcombination.
(“A left brace was mandatory here, so I've put one in.”)
I guess I need some expansion, but \expanded doesn’t help.
How can I do this?

Re: [NTG-context] SVG text alignment issue
Thanks Aditya,
I tried your suggestion, but the result is the same. Here's the XML setup
for all images in the document:
\startxmlsetups xml:img
\starttexcode
\placefloat[here,force]{}{%
\hbox{\externalfigure[\xmlatt{#1}{src}][conversion=mp]}
}
\stoptexcode
\stopxmlsetups
Here's the Markdown source document:
The source document is automatically exported as XHTML:
The XHTML is then passed to ConTeXt, whereupon the XML setup for images is
applied. The result is the same: the alignment for the text is off. Here's
an example where you can see the issue on the 16q24.3 text (far right):
https://i.ibb.co/WGh03Sr/genes.png
When the same SVG file is rendered using Apache Batik, the white text is
aligned to the middle of the black box.
Are there aAny other work-arounds?

Re: [NTG-context] Graphviz and ConTeXt
Hi,
You could just convert these separately to pdf/svg/jpg/png and then load them
as \externalfigure.
You could also use the filter module to be able to take them inline into the
ConTeXt code:
\usemodule[filter]
\define[1]\ReadFigure{\externalfigure[#1]}
\defineexternalfilter[graphviz]
[cache=yes,
readcommand=\ReadFigure,
output={\externalfilterbasefile.pdf},
filtercommand={dot -Tpdf -o "\externalfilterbasefile.pdf"
"\externalfilterinputfile"}]
\starttext
\startTEXpage
\startgraphviz
digraph G {
main -> parse -> execute;
main -> init;
main -> cleanup;
execute -> make_string;
execute -> printf
init -> make_string;
main -> printf;
execute -> compare;
}
\stopgraphviz
\stopTEXpage
\stoptext
See the filter module documentation for more details about that.
Best wishes,
Taco

Re: [NTG-context] How to print a random whole number between x and y?
Joel via ntg-context schrieb am 17.06.2022 um 16:10:
I was using this code for a long time in my document. I have a PDF

Without a better example there is no way to tell what's wrong with your
document. The most likely answer is that you try to expand part of your
code which contains the \getrandomnumber line but since \n isn't defined
yet you get the error message.
What you can try is to replace \getrandomnumber and "page=\n" with
"page=\randomnumber{...}{...}".
\startbuffer[dummyfile]
\dorecurse{10}{\centerbox{\definedfont[Sans sa 10]Page \recurselevel}}
\stopbuffer
\setuplayout[page]

Re: [NTG-context] Foonotes in Captions ... again
Hmmm, I probably was to quick. Does not really work in my real document...
I'll try to solve the issue now by integrating the notes into the caption.
Let's see if the authors accept it.
Anyway, maybe that would be a nice topic for the monthly context chat?

What's the current state of affairs regarding footnotes in floats? Both version

The problem is, somehow some images are inexplicably displayed very tiny

What is wrong in my code?
There are no parameters "minwidth" or "minheight", see
https://wiki.contextgarden.net/Command/setupexternalfigure
It’s probable that your pictures have a high resolution (dpi) defined,
so ConTeXt displays them according to that in their “natural” size.

The problem is, somehow some images are inexplicably displayed very tiny on the
page. I check the image file and they are not small, but somehow is rendered
small with the code above.
What is wrong in my code?

[NTG-context] Foonotes in Captions ... again
Hi everyone
What's the current state of affairs regarding footnotes in floats? Both version
in the example below don't quite work...
(Ideally, the note should be on the page with the float and the caption, but
the numbering should also be adjusted.)
Best,
Denis

Re: [NTG-context] Rotating jpeg image gives weird output
Thanks for your suggestions. It probably is not EXIF-related. I've opened and saved the image with MS Paint, but that did not change anything (the increase in file size aside...). Any other ideas?

Re: [NTG-context] Rotating jpeg image gives weird output
So, I've rotated the image, but now two things happen: 1. there's a weird offset (the image is moved to the right) This seems to be somehow related to the particular file. With a different file that does not happen. This can sometimes happen if the image has an embedded EXIF "Orientation" tag and you're using a buggy viewer. Really old versions of Firefox/pdf.js had this bug. If this is the case, you should be able to reproduce it with the following bash commands: convert -size 64x256 canvas:grey -fill black -draw "circle 32,128 16,112" demo1.jpg exiftool -Orientation='Rotate 90 CW' demo1.jpg -o demo2.jpg Then, include "demo1.jpg" and "demo2.jpg" in a ConTeXt file using \externalfigure. Both pictures should display as circles; if you get ovals, then it's definitely EXIF-related. 2. The output contains this line . location=local,global. location=local,global Never seen this before, which makes me suspect that maybe this isn't EXIF-related. Maybe the image is just subtly corrupted? Anyways, if the problem is EXIF-related, then opening and saving the image file with MS Paint (or any other non-EXIF-aware editor) should fix things.

Convert the PostScript file into PDF with either "ps2pdf" or

[NTG-context] stacking of marginals
If you have many marginals, they tend to conflict.
The option stack=yes should enhance the situation.
I don’t expect wonders – if there’s not enough space, then ConTeXt can’t
solve it. But it used to work better, as I can see in my magazines from
the last years.
Now I can’t see a difference between stack=yes or no:
\usemodule[visual]
\useMPlibrary[dum]
\setupmargindata[inmargin][stack=yes]
\starttext
\dorecurse{20}{%
\fakewords{5}{30}
\inmargin{\externalfigure[dummy\recurselevel][width=15mm,height=15mm]}

Hi Jan-Erik,
this will also make it:
\setupinteraction[state=start]
\definesymbol [yes] [{\externalfigure[on.svg][conversion=mp]}]
\definesymbol [no] [{\externalfigure[off.svg][conversion=mp]}]
\setupfield[setup3][width=2ex, height=2ex]

\startTEXpage[offset=1em, foregroundstyle=\ssbf]
\dorecurse{3}
{\field[check-\recurselevel]\
option \recurselevel\blank[1ex]}
\stopTEXpage
\stoptext
But what I experienced in Acrobat Reader DC (on a borrowed computer) is
that you get the standard image (only when field is enabled) when you
click elsewhere in the document.
I guess that this may be related to a missing implementation, but first
I would like to confirm you are experiencing the same.
Best,
Pablo

[NTG-context] overthinking overprinting
A question on TeX-D-L reminded me to look into this subject.
At the moment, there is \setupcolors[intent=overprint|knockout] with
\startoverprint|knockout, as defined in colo-ext.mkxl|mkiv.
I’m not sure what that does as a general setting – usually you need
overprinting for black text and lines in CMYK documents.
There are special cases where you want other (spot) colors to overprint,
but that’s quite rare, and I can use transparency features to achieve
the same (a=multiply) in an even more flexible way – as long as I don’t
need a format like PDF/X-3 that doesn’t allow transparencies.
If I declare such a format, ConTeXt just switches off transparencies and
doesn’t try to emulate (“flatten”) them as e.g. InDesign does.
So it would be nice if I could e.g.
\definecolor[OPred][m=1,y=1,intent=overprint]
OTOH there are cases where I want a black area or text to knockout the
background, these might work with \startknockout etc.
When I try my example:
\useMPlibrary[dum]
\setupcolors[
rgb=no,cmyk=yes,
intent=overprint,% or knockout
]
\setupbodyfont[modern,ss,18pt]
\starttext
\definecollector[Test]
\setcollector [Test] {\externalfigure[none][width=8cm,height=6cm,frame=on]}
\setcollector [Test] [corner=middle,location=middle] {{\bf Toast}}
\setcollector [Test]
[corner={left,top},location={right,bottom}]
{\framed{LT}}
\setcollector [Test]
[corner={left,bottom},location={right,top}]
{\framed{LB}}
\composedcollector{Test}
\stoptext
... then the text is “knocked out” regardless how set the intent.
It also doesn’t help to use \startoverprint for the Text.
The attached screenshot shows the color separation preview from Acrobat
Pro 9.
Is this broken or intended to be used differently?

Re: [NTG-context] Simple question
Don't know how if there's an automatic way, perhaps look into ctx processing
instructions.
Anyway you can use
--result=name
As you have to set quite a few options on the command line (modes, language)
you'll perhaps want to use a makefile anyway.

Is it possible to change the name of the resulting PDF file based on the

So that with a command
context language=fr mode=simple file.tex
the result is in
file-simple-fr.pdf
and with
context language=ru mode=none file.tex (or no mode given)
the result is

What is the easiest way to have a ‘database’ of translations for strings and
maybe links?
I now have 4 languages and 2 versions so 8 documents, but I’d like to have all
translatable strings together so I can maintain these in a single file. Ideally
I can do a file where the key of the translation is one language (say English)
and the translations are part of that.
Something I can call like this
\translatephrase[English phrase][nl]
\translatelocation[../LMTX-Output/without-ids/en/file.pdf][nl][simple]
and where I can maintain all the translations a bit like this:
\translationentry[English phrase]{
\definetranslatephrase[nl]Nederlandse frase]
\definetranslatephrase[fr][Phrase français]
}
}
\translatelocation[../LMTX-Output/without-ids/en/file.pdf][simple][nl][../LMTX-Output/without-ids/nl/file-simple.pdf]]
\translatelocation[../LMTX-Output/without-ids/en/file.pdf][none][nl][../LMTX-Output/without-ids/nl/file.pdf]]
Where the \translatelocation command can be used inside an \externalfigure
command and \translatephrase can be used as as text.
In the end I’d like to compile with
context language=fr mode=simple mainfile.tex
Doable?
To set language dependent texts you can use the labeltext mechanism which is
used by ConTeXt to change the captions for floats etc.
Besides the default \labeltext and \setuplabeltext commands you can create your
own instance of the mechanism for your texts.
begin example
\definelabelclass [gerben]
\setupgerbentext [en] [phrase=English phrase]
\setupgerbentext [nl] [phrase=Nederlandse frase]
\setupgerbentext [fr] [phrase=Phrase français]
%\mainlanguage[nl]
%\mainlanguage[fr]
\starttext
\gerbentext{phrase}
\stoptext
end example
To change images you use multiple sub folders where each folder has images
which the same name. In ConTeXt you can use a mode to choose which directory is
used to load the image. Another method is to map the file names of the images
to symbolic names and use only the symbolic names in your document.
begin example
\setupexternalfigures [location={local,global,default}]
\useexternalfigure [simple] [cow.pdf]
%\useexternalfigure [simple] [hacker.png]
\starttext
\externalfigure[simple]
\stoptext
end example

which directory is used to load the image. Another method is to map the
file names of the images to symbolic names and use only the symbolic
names in your document.
begin example
\setupexternalfigures [location={local,global,default}]
\useexternalfigure [simple] [cow.pdf]
%\useexternalfigure [simple] [hacker.png]
\starttext
\externalfigure[simple]
\stoptext
end example

I now have 4 languages and 2 versions so 8 documents, but I’d like to

one language (say English) and the translations are part of that.
Something I can call like this
\translatephrase[English phrase][nl]
\translatelocation[../LMTX-Output/without-ids/en/file.pdf][nl][simple]

\translationentry[English phrase]{

Hi Gerben,
a lot is doable, it depends on by whom ;)
But this looks like a quite easy case.
Of course the answer is always “Lua tables”, but I guess the
translations would be most easy to maintain in a CSV file (you can edit
it in LibreOffice or Excel, while the latter often botches the encoding).
It could look like:
key;en;de;nl
yes;yes;ja;ja
LANG;English;Deutsch;Nederlands
i.e. the first column is the keyword and the other columns contain the
translated term (so you can also change the “original” version).
(We’re using the same in a LaTeX3 project made by Marei.)
Without researching I assume there are already Lua functions to read a
CSV file into a Lua table, and the lookup is easy – since I’m not fluent
in Lua, I won’t provide the function(s) for you.
BTW there is already \translate
(https://wiki.contextgarden.net/Command/translate) that changes text
depending on the current language.
And there is the translate module that changes terms within the whole
text:
https://source.contextgarden.net/tex/context/modules/mkiv/m-translate.mkiv
Other options like .po files might be more versatile but also much more
involved.
This covers \translatephrase; for your figures I’d just just a language
variable in the path, like \externalfigure[images/\LANG/cow.pdf]
If this is always the current language, use \currentlanguage.
You can also setup the language dependent directory in
\setupexternalfigures.
Regarding modes, the current language is set as a system mode (*en,
*nl), and of course you can query modes with one of the many \doif
macros. (https://wiki.contextgarden.net/Modes)
Since it doesn’t make sense to try
\externalfigure[path/\currentmode/cow] (you never know how many modes
are active), you can set a macro or variable depending on a mode:
\doifmode{simple}{\setvariable{gerben}{level}{simple}}
and then
\externalfigure[images/\getvariable{gerben}{level}/\currentlanguage/cow]

Re: [NTG-context] SVG style ignored after double semicolon
ok, let’s get smarter.
how about sanitizing the svg-file from JFreeSVG with svgo or svgcleaner or nano
or else?
And as a side effect you’d have the file optimized, ie. a smaller size
(lossless I suppose) …
and are you sure that the ;;-issue is the only bug? After sanitizing you’ll
never know but that should be ok.
I’ve checked this. For your example it’s ok.

Re: [NTG-context] SVG style ignored after double semicolon
Hi Heinrich,
Use the SVG I provided. R and Renjin use two different SVG generators.
Renjin uses JFreeSVG when exporting as SVG. As you pointed out, there are
no issues with R because it will export an SVG file without any double
semicolons.
In other words, try this:
\startbuffer[svg]
\stopbuffer
\starttext
\placefigure{}{\includesvgbuffer[svg][conversion=mp]}
\stoptext
If you get a black square, that's the bug. If you get a white square, then
there's something different about our environment setups.
Cheers!

Re: [NTG-context] Crediting copyright on photographs
Thank-you Adam, Hraban and Richard for your suggestions.
In the end it was remarkably simple:
\starttext
\definecollector[example]
\setcollector [example] {\externalfigure[cow][width=6cm,frame=off]}
\setcollector [example] [corner={right,bottom},location={right,top}]
{\rotate[rotation=90]{\copyright A great artist}}
\placefigure [ ] [fig:cow] {A fine figure of a cow}
{\composedcollector{example}}
\stoptext
In the above the cow is drawn with the figure caption below as normal and with
the copyright text running upwards along the edge of the right-hand edge of the
image. And if you want to fine tune the space between the image and the text
then it's easy to \framed the text and play around with the size and offsets.

Using
\startplacefigure[title={complete caption}, list={description in the
table of figures}]...\stopplacefigure
you can have different caption texts, like for titles.

I often use \ininner{\rotate[location=fit]{Copyright notice}}, but
it’s
a hassle to get the placement right, don’t use it within the caption.
Using \setlayer is most reliable.

Re: [NTG-context] Crediting copyright on photographs
Hi Bruce,
The Layers page has some examples (

[NTG-context] Crediting copyright on photographs
I need to include the copyright acknowledgement / photographer credit on an
image but I'm not sure what's the best way to do it.
Option 1: I can add the acknowledgement to the end of the \placefigure caption
text:
e.g. \placefigure{A picture of a cow. Image of a cow that may or may not be
under copyright anymore.}{\externalfigure[cow][height=6cm]}
then the copyright bit will appear in the Table of Figures which I don't really
want to happen. Is there a way to truncate this?
Option 2: some magazines print the copyright credit running up the side of the
image, independently of the caption. I'd quite like to do this and wondered if
anyone had already written something they could share?

[NTG-context] recursion in a table
Hi,
I was playing with the example from
https://wiki.contextgarden.net/Scaling_Rotating_Mirroring_Clipping#Location_parameter
and tried to put it in a tabulate:
\useMPlibrary[dum]
\setupexternalfigures[width=3em,height=2em,frame=on,]
%\def\TXT{\ruledhbox{\bf(XyX)}}
\def\TXT{\externalfigure[pic]}
\starttabulate[|l|l|l|l|l|l|]
\NC\NC normal\NC depth\NC fit\NC broad\NC high\NC\NR
\HL
\dostepwiserecurse{0}{359}{45}{%
%\expanded{\setuprotate[rotation=\recurselevel]}
\NC{\expanded{\recurselevel}˚}%
\NC{\ruledhbox{X\rotate[location=normal,rotation=\recurselevel]{\TXT}X}}%
\NC{\ruledhbox{X\rotate[location=depth,rotation=\recurselevel]
{\TXT}X}}%
\NC{\ruledhbox{X\rotate[location=fit,rotation=\recurselevel]
{\TXT}X}}%
\NC{\ruledhbox{X\rotate[location=broad,rotation=\recurselevel]
{\TXT}X}}%
\NC{\ruledhbox{X\rotate[location=high,rotation=\recurselevel]
{\TXT}X}}%
\NC\NR}
%\HL % error
\stoptabulate
This works, but \recurselevel is always 0. I know I must expand it (like
in the original example), but I can’t make it work within the tabulation.
In the first column, \expanded{\recurselevel} stays 0, and
rotation=\expanded{\recurselevel} gives an error, while the \setuprotate
line has no effect (if I remove "rotation=\recurselevel", of course).
How would that work?
Also, \HL doesn’t work at the end, and the second line of the error
message makes no sense:
"""
I expect to see \noalign only after the \cr of an alignment.
Proceed, and I'll ignore this case.
mtx-context | fatal error: return code: 1
"""

[NTG-context] Centering figures that extend into the margin
Hi, I've been playing around with 'marginnote' layout similar to tufte's books. The main thing that I can't figure out is how to centre figures that extend into the margin. These should take over the whole page, but the content of the figure should be centred, which is normally the case in normal figures. Below is my try of defining a marginnote that does this, by calculating the textarea size and setting the width to that. However, I can't seem to then figure out how to center the externalfigure inside of the figure. Thanks in advance!

Hi Hraban,
slightly modifying your MWE, I think I get what might fit your needs
(see below).
I never used \flushlayer and your sample shows that it doesn’t fit here.
The layer is relative to the page, not to the paper in this case.
And the state is an option for the layer (in \definelayer), not for the
background, being "start" its default value.
Just in case it might help,
Pablo

Re: [NTG-context] placing (on) layers
Hi Willi,
thank you, I wasn’t aware that \flushlayer works this way. This was also
the problem in my real project.
And I had the wrong layer mentioned in \setupbackgrounds from another test.
Also, cropoffset was interfering in the real project, see my other mail.

if you flush a layer like in your example, then the layer is attached to the

of the \setlayerframed command . — What would be possible is to attach the

I hope this gives you a hint how to proceed..

[NTG-context] new upload
Hi,
I uploaded a new lmtx. Apart from a experimental intersection feature in
the mp library (and metafun, more will be revealed when MS an I are okay
with it) there is not that much news.
I decided to turn some test code into a mechanism which is illustrated
below. Adaptive boxes are hboxes that act a bit like glue which means
that when we hook in e.g. a graphic it can be made to adapt.
We can add some more methods if needed so maybe you see other usage. The
interface is rather lightweight and the overhead is quite resonable.

It actually uses an already present for a while low level engine feature
that we introduced as part of the math processing update:
\dorecurse
{1000}
{test \uleaders\ruledhbox{\hss#1\hss}\hskip2em minus 1em\ }
Next on the todo is to move some experimental graphic trickery related
to math (matrices) into the core but the interfacing needs some thought.

Aside from the other solution using makeup, a simpler way might be to just use
the 'page' option for positioning the float. The following MWE achieves the
same result as that with the makeup:
\setuppagenumbering[alternative=doublesided]
\setupexternalfigures[location=default]
\setupheadertexts[]
\setupheadertexts[chapter][\date]
\setupfootertexts[pagenumber]
\starttext
\startchapter [title={Chapter title}]
\dorecurse{2}{\samplefile{knuth}}
\placefigure[page]{a floating cow}{\externalfigure[cow]}
\dorecurse{4}{\samplefile{knuth}}
\blank

Re: [NTG-context] Full-page Figure?
Almost there. But if I add \setuppagenumbering [alternative=doublesided]
to the example, there is a blank page before the makeup page, and an unnumbered
blank page after. If I add doublesided=no to the
\setupmakeup options, the unnumbered blank page is not there, but there is
still a blank page before. It is seemingly forcing
a right-hand page for some reason I do not understand.

I suppose you need 'postponing'. See
https://wiki.contextgarden.net/Command/startpostponing
[One can specify a page explicitly, or, more conveniently, an offset]
First, we define a makeup and enable header, footer and page for it. Then we
can put the float inside the makeup and wrap it with \start...\stoppostponing.
Here is a MWE:
%%% start example
\setupexternalfigures[location=default]
\definemakeup
[FloatPage]
\setupmakeup
[FloatPage]
[headerstate=normal,
pagestate=start,
align=middle,
footerstate=normal]
\setupheadertexts[]
\setupheadertexts[chapter][\date]
\setupfootertexts[pagenumber]
\starttext
\startchapter [title={Chapter title}]
\startpostponing[+1]
\startFloatPagemakeup
\placefigure{a floating cow}{\externalfigure[cow]}
\stopFloatPagemakeup
\stoppostponing
\dorecurse{6}{\samplefile{knuth}}
\blank
\dorecurse{2}{\samplefile{tufte}}
\stopchapter
\stoptext
%%% stop example
Of course, I think some manual hand-tuning is required (in the final stages of
the document) in deciding the right place to put the postponing block and in
deciding what offset is best.
