Re: [NTG-context] Help with typesetting footnotes in an HTML document
Hi Denis,
Thanks for the code, I shall give this a try.
To get the html file I convert a docx file using a wordpress multisite
app called Pressbooks, a book content management system for book
publishing in various formats such as the web, pdf, epub and various xml
flavours (see pressbooks.com). My interest was that docx files could be
imported into pressbooks, edited and then exported as html which I then
used in ConTeXt to produce pdf. Pressbooks has an open source option and
they give instructions on how to self-host on a local web server, which
is what I have done (see pressbooks.org). It is, I suppose, like using a
sledgehammer to crack a nut, and the html files produced are quite
complicated. I'm still in the experimental stage with it.
Before trying out Pressbooks, I had previously produced two
books(novels) by converting docx files to epub using an epub extension
to Libre Office, then edit/clean-up the epub using Sigil epub editor.
Finally I extract the individual xhtml files and input into ConTeXt.
That was much easier and the files much less complicated, however those
books did not have footnotes so I shall have to check that out in Sigil.
I'm still experimenting to get a simple workflow for the conversion of
docx files to simple (x)html files.
Thanks again for the code.
Best Wishes
Keith

Hey Keith,
the code below should get you started. Obviously, the links in the footnotes don't

By the way, where is the HTML coming from? The dual structure for footnotes

Fair comment Denis.
I decided to try the lookup based approach on pages 85 - 86 of the xml
manual and my setups are based on those pages. I have to admit that I find
the xml manual a wee bit difficult in places since xml is outside my expertise.
I attach my tex and html files which should save some copy and pasting.

Re: [NTG-context] Absolute positioning of \startcombination... \stopcombination
Thanks for your reply Pablo. I didn't see it till just now because for
some reason it ended up in my junk folder, along with a number of other
ConTeXt messages. You will probably have seen my reply to the list with
the three solutions, now we have four!
Yep, I know that A4 is the default page size and I always start with
that but sometimes I play about with page sizes when typesetting and so
can just change when coding.
In the document I'm working on, some pages will only contain images
and/or combination of images so I went down the Layers route since this
also allows me to absolutely position these images on the page.
Thanks again for your help!
Best Wishes

Hi Keith,
I think the following sample might achieve what you want:

\setuplayout
[backspace=2.5cm,
topspace=1cm,
height=28cm,
width=17cm,
header=0cm,

\definelayer[test3]
%[x=.5\paperwidth, y=.5\paperheight]
[x=.5\textwidth, y=.5\textheight]
%\setupbackgrounds[page]
\setupbackgrounds[text]
[background=test3]
\starttext
\setlayer[test3][location={middle}]
\framed[offset=overlay]{{\startcombination[nx=3,ny=1,distance=15mm]
{\externalfigure[cow][width=15mm]}{}
\rotate[rotation=90]{\externalfigure[cow][width=15mm]}{}
{\externalfigure[cow][width=15mm]}{}
\stopcombination}}
\null
\stoptext
BTW, A4 portrait is the default page size.
\setupbackgrounds is the standard way to place layers.
Page and text centering would require different positions (I have
commented out the option for page centering).
I hope it helps (since I’m not sure I’m getting your point here),
Pablo

[NTG-context] Absolute positioning of \startcombination... \stopcombination
Hi,
I would like to position a combination of images where the centre of the
combination coincides with the centre of the text area of a page. In the
example below I have made the combination into a layer thinking that
this would be the easiest way to position it where I wanted. However to
position in the centre of the page I would need to know the size of the
combination and use this to calculate the x and y values for positioning
of the layer. I have looked at the Wiki page on image size of
combinations but still cant figure out how to do it. Any suggestions on
how to go about this or is their a better way?

[NTG-context] Problem with \setuplayout parameters being ignored
Hi
I'm having a strange problem with the \setuplayout command with the
parameters being ignored. In the code below the only parameter which
does get setup is the backspace parameter, the header, footer, width,

probably missing something fairly obvious so hints would be helpful. The
document I'm trying to setup will probably be a maximum of 50 pages and
I would like to reduce the space at the top and bottom of the page.

Thanks for this code Hraban. I tried this last night and it worked really

[NTG-context] Graded Transparency in MetaFun
Hi all
I'm trying to create graded transparency over an area similar to the
effect produced using lmt_shade, where one colour goes to another colour
over a continuum, but with graded transparency we would go from say 0 to
1 transparency, for a single colour. See the MWE below.
I have tried this by creating a loop which draws a linear path, yshifted
the thickness of the pen, with transparency calculated for each step
over the a predetermined height on the page. I have also tried a similar
way for a circular path but in this case the path is repeatedly drawn
scaled in a loop. The MWE below works OK but when I zoom into the graded
transparency areas lines begin to appear which would suggest that their
is a better way to do what I want. This is borne out if you zoom into a
lmt-shade area, one colour smoothly becomes another colour. I've put
examples of this in the MWE. I'm guessing the way lmt_shade areas are
drawn is the way to go. Is this likely to be easy to code for what I
want to do?
Best Wishes
Keith McKay

Hi Tommaso I use TeXworks with ConText stand alone LMTX. To set it up to run context do the following. Open TexWorks and then click on TexWorks in the menu bar then Preferences.

Next to Processing Tools is a + button. Click on this and a "Tool Configuration" window appears. This is where you enter the details for processing by ConTeXt and this is how I have set this up on my mac mini M1. Name: LMTX % Here you need to use the Browse button to get to the mtxrun.

Re: [NTG-context] Problem with a defined colour in MetaFun
Hi Wolfgang,
Thank you for your reply. I did as you suggested but it still never
worked. However it did make me delve further into the Metafun,
LuaMetaFun and the Colouring ConTeXt manuals where I found examples of
the *resolvedcolor* helper which I used as follows:
definecolor [name = "myColor", r = uniformdeviate(1), g =
uniformdeviate(1), b = uniformdeviate(1)];
for loop..
fill unitsquare xscaled 5cm yscaled .5cm shifted (7cm,i*cm)
withcolor(r[resolvedcolor("myColor"), white]);
endfor;
I also found the *namedcolor* helper and I could use it as follows:
fill unitsquare xscaled 5cm yscaled .5cm shifted (1cm,(2*i)*cm)
withcolor namedcolor("myColor2") ;
However, for some reason it did not work in:
fill unitsquare xscaled 5cm yscaled .5cm shifted (7cm,i*cm)
withcolor(r[namedcolor("myColor"), white]);
//
Thanks again for your suggestion//
Best Wishes
Keith//

Hi,
In the MWE below I define an rgb colour, myColor1, using random
numbers for the r, g and b components. I then use it to fill a
unitsquare the size of the page, which works as expected. In the loop
that follows I then use the defined colour, myColor1, along with
white and the variable r to create shades of myColor1 as in the MWE
below. However, myColor1 is not recognised in the loop and seems to
be replaced by black, although if I use a predefined colour, in this
case BurntSienna from the crayola collection, it works as expected.
I have tried a number of ways to get this to work as shown in the

Re: [NTG-context] Setting up zint on a mac with macOS Montery Version 12.3.1
Hi All
I created the symbolic link as suggested by Bruce and Luis and still got the
error message
optional> unable to locate library 'libzint'
in my text editor. I use TeXworks. However, I thought I would try running from
the Terminal app and it worked. It found libzint and output the pdf with both
barcodes and the qrcode. I have no idea why it works in the Terminal and not
TexWorks, I'm guessing I have a path issue which I need to investigate.
Notes
1) My machine is a mac-mini-M1 with macos Monterey and I'm running the latest
ConTeXt version
2) Bruce noted that my Homebrew was installed in a non-standard location so I
checked on the Hombrew website and it is installed in opt/homebrew for Apple
Silicon i.e the M1 chip. Maybe Bruce's homebrew was installed on an earlier
version.
Thanks to Luis and Bruce for their suggestions.
Best Wishes

Hi All
I have been struggling today trying to setup and use the Barcode module zint in
ConTeXt and failed. I have followed the instructions on the wiki
(https://wiki.contextgarden.net/Barcodes ) but with some changes as follows.
Which maybe why I failed.
1) I downloaded Zint using Homebrew since I'm using macOS, and installed it
according to the instructions.
2) Since I'm using LMTX I looked for the file libzint.dylib and found it in
/opt/homebrew/Cellar/zint/2.10.0/lib . This is different from the path given on
the wiki. The directory contained three files, two of which were aliases,
libzint.2.10.dylib and libzint.dylib, and an exe file libzint.2.10.0.0.dylib
You have Hombrew installed in a non-standard location. Mine is in
/usr/local/Cellar with the executables linked into /usr/local/bin.
But, assuming other Homebrew commands work when run from Terminal then you
might still be okay.
3) I created the path $TEXROOT/tex/texmf-osx-64/bin/lib/luametatex/zint and
copied libzint.2.10.0.0.dylib into but replaced dylib with 'so' as suggested on
the wiki instructions. So I basically added lib/luametatex/zint to
texmf-osx-64/bin .
"Yes" to creating the path but "no" to copying. Create a symbolic link instead.
So, in Terminal:
$ cd $TEXROOT/tex/texmf-osx-64/bin/lib/luametatex/zint
# In my case I used the following:
$ ln -s /usr/local/Cellar/zint/2.10.0/lib/libzint.dylib libzint.so
# For you with Homebrew in a different location, try:
$ ln -s /opt/homebrew/Cellar/zint/2.10.0/lib/libzint.dylib libzint.so
Then steps 4 and 5 as below. I ran the MWE below: the ISBN worked, the ISBNX
didn't, the QR code did. This is on Monterey.
4) I ran mtxrun --generate to update the database.
5) I ran the MWE below but no barcode appeared. The console output shows:
modules > using user prefixed file 'libs-imp-zint'
modules > 'zint' is loaded
however further down the output it gives:
optional> unable to locate library 'libzint'
I have tried renaming libzint2.10.0.0.so to libzint.so, but still no barcode.
Is their something I am missing? Tips or hints appreciated.
