Hi,
is there some mechanism (directive?) that gives me a list of files that
were involved in making a PDF? Preferably only those outside of the
texmf trees, but I could filter that myself.
(With "latexmk -recorder somelatexfile" I get the file list as a .fls
file.)
My goal is to commit all used images to my git repo, while I often have
a big collection of images that I didn’t use in the end and don’t need
in the repo.
subconscious you know the answer:
look at the log file
files are tagged with "start used files"
of course you can also try
\enabledirectives[system.dumpfiles=lua]
and stare at the resulting job log file (jlg)
(the default is xml but i noticed some empty entries in there ... a very
old feature so i need to travel back in time now)
if files are missing let me know

in lmtx { } in math is just grouping, so no ordinary math atom is

With STIX Two, c2sc (and smcp) works with any language as long as one

the chosen script. With New Computer Modern, it just doesn't work with
any latin text no matter the script chosen. That is, plain small caps
work, caps to small caps don't. What could be the reason to it? Is there
anything I could do to mitigate it?
you can try
\definefontfeature [capstosc] [c2sc=always]

Do you have a bin then? And ran mtxrun --generate --luatex ?
Sorry, I didn’t want to hijack the thread.
Good hint – of course I don’t have a luatex binary besides that from
TeX live 2023 that doesn’t work with latest LMTX/MkIV.
hm, normally it should because nothign gets added to luatex but maybe
one of these 'change default behaviour startup due to whataver
security policy' interferes (not much we can do about that apart from
trying to be in sync)
TeX Live binaries are a tangled web of symlinks, at least on OSX.
I finally found the real binary in
/usr/local/texlive/2023/bin/universal-darwin/, but symlinking it into my
~/context/tex/texmf-osx-64/bin doesn’t help, I get:

… the same "unknown script" error as without the symlink, when the
luatex binary is found on the PATH. And yes, "mtxrun --generate
--luatex" worked.
Might it be a conflict of texmfcnf.lua ?
could be ... there was some change between tl2023 and tl 2024 and then
again after the tl 2024 release
and indeed this symlink chain is a problem, hard to follow also, and
afaik a long term side effect of a gwtex / mactex / texlive transition
but i guess you can just install and then adapt the path to your liking,
no need to operate in the texlive structure

I wonder if your test environment is really equivalent to a fresh
Alpine install, or if there might be any previously installations that
are allowing it to appear to succeed. Does it work if you try inside
Docker?
I'm not sure what else I can try. Where's that `luatex` call supposed
to be found?
Does it work without --luatex, i.e. does it work for LMTX but not MkIV?
mtxrun --generate --luatex works for me (on OSX), but context --make
--luatex doesn’t since forever.
Do you have a bin then? And ran mtxrun --generate --luatex ?

Very nice, thank you!
I see some similarities to the "visible on" technique [1], I posted in a
previous thread.
You mean the horrible transparency hack there?
What comes there really handy are range specifiers, what seems not possible
with this interface.
For example: "visible on=<2->" renders the content on every page except the
first one
or "visible on=<1-5,13-15>" on the first page up to the fifth page and from
page 13 to 15.
The mechanism stems from the Beamer overlay specifications, see section 9.3 of
the manual [2]
and can be much more complicated with modes (section 9.6.2).
I don't know beamer other than seeing presentations at meetings but I
assume that it has some accumulator. We do have steppers in mkii / mkiv
already in the presentation styles. The conceptual cleanest of them
depends on the viewer and free ones never catched up so that one is
acrobat specific. The stacker discussed now is just similar to the
metapost one but then at the tex end. (A quick hack with room for more a
bit more effiency if ther ei sneed for it.)
To add this to the new interface, if you want that, the stack layers above need
some kind of order,
which is implicit for numbers:
```
\definestacking{one}
\definestacking{two}
\definestacking{three}
\definestackingorder{one,two, three}
...
\setupstacking[criterium={one-three}]
```
The order could also be implicitly defined after the order of the
\definestacking calls.
Or would it be possible to have numbers always automatically (additionally)
available as stacking layer?
So that this "just" works:
```
\startbuffer
This is a test \stacking [1] {and a proof} of \stacking [2] {concept} indeed.
\stopbuffer
...
\setupstacking[criterium={1-}]
```
I also wondered, if it is possible to define a lot of layers semiautomatically
in Lua
(in some graphics I needed around 20 layers). It seems that numbers in layer
names currently are not allowed.
Is code like this possible somehow?
```
\startluacode
for i = 1, 20 do
context.definestacking(string.format("l\letterpercent.d", i))
end
\stopluacode
```
The next version already will have this:
%D For Aditya Mahajan: ranges and such.
%D
%D \starttyping
%D \starttext
%D \startstackingsteps[1,{1:2,201},{1:3,301},{1,2,4},{1-5},{1-6},{1-7}]
%D \startTEXpage
%D \startstacking[1] \framed{ONE}\stopstacking
%D \startstacking[2] \framed{TWO}\stopstacking
%D \startstacking[201] \framed{MORE} \stopstacking
%D \startstacking[3] \framed{THREE} \stopstacking
%D \startstacking[301] \framed{INDEED} \stopstacking
%D \startstacking[4] \framed{FOUR} \stopstacking
%D \startstacking[5] \framed{\im {\sqrt {
%D \stacking[6] { 1 + x ^ {
%D \stacking[7] { 2 } } } } }}
%D \stopstacking
%D \stopTEXpage
%D \stopstackingsteps
%D \stoptext
%D \stoptyping
The range interface is not different from the one we use in other places
so it was a braindead patch. Numeric stacking id's don't need to be
allocated. The example shows that it is rather general applicable
although there are some border cases (that if needed we can intercept
but I assume sane usage).
No upload yet unless there is a hurry.

It's an already old feature but probably not that well known. If needed
I can make something similar at the tex end.

Thank you for the example, but learning metafun is another chapter and the
graphics are much more complicated than the minimal example given.
I saw that you pushed an updated version that fixes the bug [1]. Thank you!

The next upload will have an example of something similar at the \TEX\

be found in:

I tried reinstalling, but same result: error, no format found with name:

And the simpler fact is that everything worked as normal before I upgraded.
I tried deleting texmf-cache, running mtxrun -- generate and context

Don't know if it is relevant but after running context --make I see an
error line:

But that would seem to be a different error to the 'no format found'

That line loads typo-ling.lmt so does something go wrong there?

Probably only Hans (or Wolfgang) can give a complete answer here. But
\startsetups [*default]
\directsetup{*reset}
\frozen\brokenpenalties 1 1\relax
\stopsetups
works here.
/Mikael
currently \brokenpenalties only takes one setting
\permanent\protected\def\setpenalties#1#2#3%
{\ifdefined#1%

\plusone#3\relax

\numexpr#2+\plusone\relax\space\expandedrepeat\numexpr#2\relax
{ #3}\zerocount\relax

PS
An interesting new feature is the possibility to set penalties depending
on left and right page, by using options. For example
\startsetups [*default]
\directsetup{*reset}
\frozen\clubpenalties 3 options 4 1500 3000 250 500 0 0 \relax
\stopsetups
sets club club penalties 1500 for first line and 250 for second for
going from left page to right page (and then 0 for the rest) and 3000
for first line and 500 for second (and rest 0) for going from right page
to left page.
I hope this helps a bit.

I think Acrobat may be misbehaving here (requiring some optional content as mandatory). dunno, if you can create examples i suppose we can reverse engineer them because the standard is fuzzy I’m afraid that the patch is needed since /ByteRange excludes a blank space before the value of /Contents that is in the temporary file (tmpfile). i need to test more Perfectly fine for me. Of course, it should be tested more. The blank space (marked above with the underscore) is included in the hashed file (tmpfile), but it is not included in the /ByteRange. This is the reason why we can only have digest mismatch. yes but that what i noticed when testing: mupdf, qpdf, acrobat, etc .. trial and error is not to add that one Sorry, but I have to be missing your point completely. /ByteRange considers this part of the document to be written as: << /ByteRange [ … 006421 010520 000384 ] /Contents<3… But document is written, hashed and signed: << /ByteRange [ … 006421 010520 000384 ] /Contents <3… Of course, the value of the contents hasn’t been hashed, but the blank space between /Contents and is value has been hashed. i know but when i tested with q and m that spaces was kind of fuzzy so i stuck with what seemed to work As far as I know, this has to be a reason for digest mismatch (or a huge hash collision). could be (depends on checker) but it we change that we also need to change the verfy offset (so two patches) As far as I can remember, this is mandatory for PDF-2.0 (and highly recommended for previous versions [although not required]). not sure what you mean, 2.0 demanding signing? Not at all. Sorry for my poor wording. From the PDF-1.7 spec itself (https://opensource.adobe.com/dc-acrobat-sdk-docs/pdfstandards/PDF32000_2008.pdf#search=ByteRange): This range should be the entire file, including the signature dictionary but excluding the signature value itself (the Contents entry). Other ranges may be used but since they do not check for all changes to the document, their use is not recommended. When a byte range digest is present, all values in the signature dictionary shall be direct objects. Signatures in PDF-2.0 loose their possibility of other ranges than the entire file. Their use is simply not allowed. so more limited then to basically two ranges Sorry for insisting, but please don’t require plaintext password in the command line (again, OpenSSL prompts for it). not if we use the library Weird, on both Linux64 and Win64, the openssl runner requires the openssl binary to be installed. i meant the --library option Many thanks for your help, Hans - Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl - ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://mailman.ntg.nl/mailman3/lists/ntg-context.ntg.nl webpage : https://www.pragma-ade.nl / https://context.aanhet.net (mirror) archive : https://github.com/contextgarden/context wiki : https://wiki.contextgarden.net ___

https://mailman.ntg.nl/archives/list/ntg-context@ntg.nl/message/ECSXLVMT3TMQBIHA2UZJPWJN7OVV5334/attachment/2/mycert.pfx
(I sent it myself).
Here is a sample document (actually provided by Hans):
\setupinteraction[state=start]
\definefield[signature][signed]
\defineoverlay[signature][my signature]
\starttext
\startTEXpage[offset=1ts,frame=on,framecolor=darkblue]
sign: \inframed[background=signature,framecolor=darkred]
{\fieldbody[signature][width=3cm,option=hidden]}
\stopTEXpage
\stoptext
After compiling the sample, you need to run:
mtxrun --script pdf --sign --certificate=c.pfx --password=ABCabc doc.pdf
i use a pem
Password will be prompted again ("ABCabc"), since it is an encrypted
certificate (also for the public part).
Could anyone confirm the following issues?
1. The signature I get is wrong, unless I apply this patch
(https://mailman.ntg.nl/archives/list/dev-cont...@ntg.nl/message/T3OCKVZWTUTIXCSOKIFRVJ4X76MROZHE/attachment/3/byterange.diff
[sent by myself to the devel list]).
2. I cannot get any signature display in Acrobat. Does any PDF viewer (I
have tested this with pdfsig from poppler and MuPDF-GL) display the
digital signature at all?
this whole digitial signing is a bit of a scam imo ...
- one has to buy a specific kind of certificate
- often one is supposed to use some token
- when the root cert expires one has to resign
- reader has root certs built in and checking is supposed to be online
- it doesn't come cheap and supporting / testing is not something one
can expect for free (so i can't really test it)
... so just some business model and not really something one can do out
of the box
... apart from ...
- just sign with some certificate and don't expect viewers to do something
- offer a service to upload the document for checking when a user is in
doubt
- that can be done without root cert and basically works as long as the
service works
concerning the suggested patches: this <whatever> boundary is a
bit fuzzy and i found that different viewers / checkers expect either or
not +/- 1 but i didn't check recently if things have improved
if we know the specs and have way to test ... no big deal to fix a few
offsets

This way, the resulting PDFs contain the full graphic on every page, but parts
of it are invisible for a specific page.
One of these files is attached as an example.
The problem is to embed these PDFs into a ConTeXt document.
For example, this MWE seems to not respect transparency (see mwe.pdf):

I use Okular/Poppler as PDF viewer.
Can I fix this somehow or is it a bug somewhere deeper?
next time check the file that you include ... it has no transparency (it

I guess I’ll have to live with that for now (of course this isn’t really a problem, but a bit unpleasant to look at when you’re used to the straight lines in LaTeX). Just wanted to add that I can see this artifacts quite clearly on a 13 inch 1080p screen in the PDF viewer (depends on zoom level, on some zoom levels I see nothing) and not only when enlarging a screenshot. After all, it’s visible in my attached screenshots even if displayed in their original resolution. (Naming of my screenshots wasn’t very clear, zoomed.png is zoomed-in in the pdf viewer, not a zoomed-in screenshot.) The "left radical + rule" isn't perfect either, because it depends on overlap. Depending on the font you can see issues at the connection (actually these might be obscured by aliasing at low res). You can try that outside lmtx with different fonts. Also, because rules are often rendered differently from glyphs (and rules can use either a line or rectangle fill) it's always been an issue (which is also why engines have some heuristics for choosing one or the other method). And, as mentioned, vertical extenders also use the same etechnology as we now use for radicals, it's just that there was never a concept like that in engines for radicals. Arrows sit in the same category and also use the same glyphs so there one can observe the same. Actually, even in traditional tex arrows are made from minusus and an arrowhead overlapping piecewise. Maybe viewers will catch up.

Indeed we can have:
local namespace = tokens.getters.macro("??measure")
function tex.getmeasure(name,asdimen)
local value = tex.getdimensionvalue(namespace..name)
if asdimen then
return value .. "sp"
else
return value
end
and when you want to avoid the namespace you can do:
function tex.getmeasure(name,asdimen)
local value =
token.getexpansion("\\tointeger\\measured{"..name.."}")
if asdimen then
return value .. "sp"
else
return tonumber(value)
end
end
which is some 4 times slower. It'sindeed not documented (although there
are some examples in accessors-001.tex) but it's in one of my todo's
because I can use it in some places (there ar emopre such todo's) after
which it will be discussed in one of the lowlelvel manuals
i'll add tex.getmeasure to the core (but a bit different)

That seems to me to be a very elegant solution to the next two problems that were actually still ahead of me. And now to my initial question, which I didn't specify precisely enough. I have the following workflow in mind: 1. I have an XML file (TEI-XML), 2. then, following your brilliant suggestion, I will create an xml-analyze-template.tex file and customise it. 3. As you suggest, now one would actually use context --environment xml-analyze-template.tex file.xml to typeset in a pdf file. But I would like to convert all the XML nodes into the ConTeXt typesetting language, and then edit/correct the text and maybe some structure in this *.tex file. And here comes my question: Can I use context to convert my XML-file 'file.xml' into a ConTeXt-file 'file.tex' instead of typesetting it as a 'file.pdf'. What do you want to tweak. HEre is the lowest level approach: test 1 test 2 test 3 But quite some can be done when processing and there are mechanisms to inject e.g. page breaks using processing instruction.

i used hbox for making phrase unbreakable.
How can you put all the code in the one Lua function and not need to put hbox
or goto function outside of Lua?
\startluacode
interfaces.implement {
name = "Hashtag",
public= true,
protected = true,
arguments = "string",
actions = function(str)
context("{\\nohyphens\\letterhash %s}",string.gsub(str," ","_"))
-- str = string.gsub(str," ","_")
-- context.bgroup()
-- context.nohyphens()
-- context.letterhash()
-- context(str)
-- context.egroup()
end
}
\stopluacode

[NTG-context] Re: build_parshape and \getshapetext - need for a deeper understanding
On 5/19/2024 2:29 PM, garu...@azules.eu wrote:
I still get some difficulties with build_parshape, \getshapetex and sectionning.
I though I find a solution by removing \blank with
\setuphead [subsection] [before=, after=, style=,
command=\MySubSectionCommand, alternative=text ]
But actually it's not enough : when I add text before the first section, new
issues appear.
I tried to build a MVE by refactoring and tidying as much as I could.
It build 3 comparative pages (i) basic issue, (ii) solution, (iii) remaining
issue.
Your guidance are most welcome :-)
you have to fight several issues:
- parshapes being reset at the end paragraph (handled here by luametatex
context)
- parshapes operate on lines, not dimension (i might add an aletnative
one day)
- you use a bit old mechanism (checkout the luametafun-paragraphs chapter)
Now, is there a solution? It really depends on the circumstances, so
here is one.
\setupbodyfont[11pt]
\definemeasure [mywidth] [7cm]
\definemeasure [mywidtha] [5cm]
\definemeasure [myheight]
[{\the\dimexpr\baselineskip*37+\lineskip\relax}]

\startuseMPgraphic{shape:1}
path p ;
numeric mywidth ; mywidth := \measure{mywidth};

numeric myheight ; myheight := \measure{myheight};
numeric myheighta ; myheighta := \measure{myheighta};
numeric myheightb ; myheightb := \measure{myheightb};
p := (0,0)-- (mywidth,0) --
(mywidth,myheighta) -- (mywidtha,myheighta) --
(mywidtha,myheightb) -- (mywidth,myheightb) --
(mywidth,myheight) -- (0cm,myheight) -- cycle;
build_parshape(p,0,0,0,\baselinedistance,\strutheight,\strutdepth,\topskip)
;
path SavedShape ; SavedShape := p ;
\stopuseMPgraphic
\startuseMPgraphic{shape:2}
SavedShape := SavedShape shifted (0,-ypart urcorner OverlayBox) ;
SavedShape := SavedShape shifted (0,positiony("test")) ;
fill SavedShape withcolor red;
setbounds currentpicture to OverlayBox;
\stopuseMPgraphic
\showframe
\defineoverlay[myoverlay][\useMPgraphic{shape:2}]
\setupbackgrounds[text][text][background=myoverlay]
\startsection[title={test}]
\startshapedparagraph[mp=shape:1]%
\setupalign[verytolerant,stretch]%
\hpos{test}{!}\samplefile{tufte}
\samplefile{tufte}
\stopshapedparagraph
\stopsection
The "test" position is hard coded but should be namespaced, the ! can be
a \strut instead.
So, more thinking from the end of the text flow.

[NTG-context] update
Hi,
This weekends update:
- we're currently checking the upcoming math manual and in the process
we streamline some mechanisms
- as part of the BT presentation about par passes we introduced
\toddlerpenalty but we leave it to the user to guess what that is (it
fits into widow, club and orphan penalty collection)
- we could already produce pdf 2.0 but especially when one mises with
older files, some care is needed; the inclusion 'compact' mechanism has
been cleaned up a bit and the merge interface is converging (it has to
do with efficient font sharing, cleanup and fixing of files outside our
control); when one has issues with inclusion, try with compact= (set to
nothing)
- although we're mostly done with tagging it will get some attention as
we go; it's mostly about playing safe and getting valid pdf's
- for rhaban (posters) another fancy feature was added:
\startTEXpage[offset=1ts]
\samplefile{tufte}\removeunwantedspaces\space
\startshadow[contrastcolor=red,weight=100]\blue\samplefile{tufte}\removeunwantedspaces\stopshadow\space
\samplefile{tufte}\removeunwantedspaces\space
\startshadow[contrastcolor=red,weight=100,dx=0,dy=0]\blue\samplefile{tufte}\removeunwantedspaces\stopshadow\space

Hi, Hans! Thank you for the update! I'm curious about the following
issue: when I use Latin Modern (by default), a thick, filled line is
drawn next to the radical. However, when I use another font such as TeX
Gyre Schola, I get something similar to outlines-003.pdf, which is, in
turn, similar to the result of applying PDF effects. So, shouldn't this
result be the default? Thanks a lot again.
it depends on how a radical is composed; we try create an extensible
using snippets which looks better in the case of fontd where rules (have
to) have roun dcorners etc

the diacritics look fine in both ConTeXt and unicode editor MS Notepad.
So if there is something wrong, it must be in a more recent version.

Ahang-Regular has no width settings for the marks so we need to zero
them. Tahrir_Regular has widths but these we explictly need to zero with
a pseudo feature then. (What are the assumptions when we do arabic? That
marks are to have zero width?)

Since I've become an expert on tuc files since yesterday (ha!): if I compare the tuc from
a mkiv and a mkxl run, I see that mkiv produces an entry ["lastrealpage"]=9 in
the references table, mkxl doesn't. This appears to be the relevant bit, and it is
connected with the replacement of realpageno by c_realpageno in line 638 of strc-reg.lmt
references.lastrealpage = texgetcount(c_realpageno)
Let's seen if we can make Thomas more of an expert as he's zooming in on
the issue:
extendregister {
metadata = { name = name },
references = { abel = label },
}
Let me know if you't see it.
Possibly related: I noticed last week that mkxl does not update the legacy
counter \pageno any more for every page.
i'll check it

[NTG-context] Re: Why don't footnotes appear in floats or figures?
On 4/22/2024 2:45 AM, Joel via ntg-context wrote:
I'm three days out from sending my work to an editor, and found some
serious problem: many footnotes just aren't rendering.
I have a history text that uses ConTeXt-SBL for the citations, as such,
it has lots of footnotes. Sometimes the footnotes are just in the main
text, but sometimes also in figure captions, inside floats, inside
tables that are inside floats, inside tabulations inside floats, etc.
What I find alarming is it is frequently not rendering all of the
footnote messages at the bottom of the page. The actual footnote number
within the body is rendered, but no number is listed in at the bottom of
the page. So I might see a list of footnotes, for instance, on page 1, I
only get footnotes 1, 2, 3, 5, and 6, but 4 was mysteriously skipped.
---
1 message
2 message
3 message
5 message
6 message
After a lot of trial-and-error and checking logs and checking my BibTeX
files for errors, running everything through BibTex Tidy, etc., and
failures to make a minimum working example, I found a single pattern:
If the footnote marker appears on the SAME page as the footnote text, it
has no problem rendering the footnote. But, if ConTeXt decides to move a
float a page or two later on--as it frequently seems to do---such that
the footnote marker and footnote text at bottom of page should be on
DIFFERENT pages, the footnote message at the bottom of the page won't
render.
I've seen some 2+ year old mailing list posts suggesting ConTeXt might
have issues with footnotes; they appear to be similar to my issue--is
that still a problem? Is there a fix or workaround? Old fixes I could
finding in the mailing list don't seem to work with current versions of
ConTeXt anymore.
you need to consider the complications of such notes ...
- tex needs to take the notes into account when determining a page break
- it does so by the insert mechanism
- when floats can't be placed they also become inserts (top and bottom)
- when there are inserts in inserts th eproblem becomes more complex (so
notes inside floats)
- in traditional tex deeply burried inserts disappearm less so in lmtx
There are things that are hard to get right. This works:
\startpostponing
\startplacefigure[location=here,title={test \footnote{oeps 1}}]
\blackrule[width=1tw]
here
\footnote{hello 1} and
\footnote{hello 2} and
\footnote{hello 3} done
\stopplacefigure
\stoppostponing
\dorecurse{10}{\samplefile{tufte}\par}
Because here the inserts (notes) will migrate but even then one can get
them out of order (unless we renumber, which then is sensitiev for
oscillation).
I occasionally wonder if top floats could be done more directly but
bottom notes still would have an out-of-sync problem

(1) I tried placing a table inside a startitemize environment, as
instead of it not compiling, it left a message in the document warning
that wasn't supported.
(2) In another case, I had an image that ConTeXt couldn't find, as I
mispelled the filenmame, and it fully compiled and made a PDF, without
me noticing.
(3) Or maybe in some case, a font couldn't be found for a specific
character, so a single character in the file isn't displaying.
Those are just some examples; I intended for something to be printed
on the PDF, but it isn't showing there.
Since a document of this size will have a lot of messages, is there a
way to adjust the settings, from "show everything" to "show some" to
"show only serious errors"? Or maybe to use > to send the errors to
another file for careful study? (using Linux if that matters)
You can enable trackers like
\enabletrackers[figures.*]
But that just gives more log messages for debugging.
You get the list of all trackers with:
context --global m-trackers.mkiv
For your use case, directives are more helpful, like
\enabledirectives[logs.errors=*] (i.e. break at every error)
AFAIK that just handles missing characters, references and modules ATM,
but this information might be outdated.
You get all directives with
context --global m-directives.mkiv
often the log files has some summaries at the end

No, I must admit I don’t like the first two paragraphs. The question is “what

I agree. It sounds the same as "we're not msword" or "we're not google

is that they use the tex language / ecosystem.)

Hello,
It seems, that the referencing mechanism is failing. I detected this with the
January version and the current version: 2024.04.01 08:59.
Could some one confirm this?
It fails for me as well, when "mode=columns" is used.
compare with and without mode columns:
\starttext
\enablemode[columns]
As we see \doifelsemode {columns} {in \in {table} [demo-1]} {below}
we can have
more than one cell in a row.
\startplacetable[mode=columns,reference=demo-1]
\externalfigure[cow][width=\textwidth]
\stopplacetable
\samplefile{tufte}
\stoptext
so basically we have an "at the spot" placement or a float
