Re: [NTG-context] Unicode normalization and Hebrew in ConTeXt
Thankfully, it looks like this was just a problem with my implementation of
the OpenType feature and not with ConTeXt's handling of it! (I worried that
it might be ConTeXt when I saw that XeLaTeX was handing the feature
correctly.) Hans graciously helped me identify the problem, and everything
looks good now!

The “luacondition 733” is the \ifxmlatt . You get these numbers because the
command is
defined using lua ‘interfaces.implement’ (lxml-ini.lua) instead of directly as
a TeX conditional.
And yes indeed, the new lua-defined commands are hard to derive from the log
information
(for the other Hans: is this reporting not controlled via ‘public=true’ ? ).
Best wishes,
Taco

Many thanks for your reply, Hans.
I’m afraid I don’t know how to make the commands work:
\setupexternalfigures[location=default]
\definelayer[hi]
[x=.5\dimexpr\framedwidth\relax, y=.5\dimexpr\framedheight\relax]
\setupbackgrounds[page][background={foreground, hi}]
\starttext
\startTEXpage
\framed[frame=off, offset=none]
{\setlayer[hi]{\color[red]{hi}}
\externalfigure[cow-brown]\framedheight}
\stopTEXpage
\stoptext
In this case, \getfiguredimensions would work, but I don’t know how to
deal with a pure text box.
BTW, is there a way to have TEXpages numbered? "pagestate=start" seems
not to work here.
Many thanks for your help,
Pablo

Re: [NTG-context] Unicode normalization and Hebrew in ConTeXt
Shouldn't dlig automatically be enabled under the "hebrew" feature set? In
font-pre.mkiv, hebrew inherits from semitic-complete, which sets dlig=yes.
Still, if I explicitly add dlig, as in the following example, things
change, but they still aren't right:
```
\starttypescriptcollection[keteryg]
\starttypescript[serif][keteryg]
\definefontsynonym[Serif][file:../fonts/KeterYG/KeterYG-Medium.ttf][features=hebrew]
% all the necessary Hebrew features, including dlig
\stoptypescript
\starttypescript[keteryg]
\definetypeface[keteryg][rm][serif][keteryg][default]
\stoptypescript
\stoptypescriptcollection
%Set up the main font:
\setupbodyfont[keteryg]
%Set up right-to-left alignment:
\setupalign[r2l]
%Explicitly add dlig (in case it wasn't there already):
\definefontfeature[plus-dlig][dlig=yes]
\starttext
\addff{plus-dlig}
שֹׂבַע
עָשׂוֹר
קֹשֶׁט
שֹׁשַׁנִּים
עָשׂוֹר
מֹשֶׁה
שַׁלֹשׁ
\stoptext ``` In examples 1, 3, 4, and 6, the *holam *of the preceding
letter (which should have been stripped in the contextual substitution)
just seems to have been moved farther up. In fact, the output looks like it
would look if I turned off the reordercombining feature. (And indeed, if I
manually reorder the glyphs to the Hebrew Layout Intelligence order, then
the results look like they did when I just used the "hebrew" feature.)
I may have forgotten to attach the font file I was using for this test. If
that is the case, it is available at https://github.com/jjmccollum/Keter-YG.

Re: [NTG-context] compression for multimedia objects

They where so generated, that they could be compressed in a zip file from 254MB into less than 25MB. The resulting PDF file was less than 25MB. With the current latest, compression for multimedia objects is disabled. The same PDF document takes about 254MB. I don’t know whether this is intended. In that case, could we have an option to compress embedded multimedia objects? indeed intended because zipping already compressed files makes no sense (I know that those mp4 files are crappy, but I can’t control the crap others generate.) i'll add 'compress' to the options 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 / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___

Re: [NTG-context] paper dimensions for TEXpage

Dear list,
I have the following sample:
\definelayer[hi][x=.5\paperwidth, y=.5\paperheight]
\setupbackgrounds[page][background=hi]
\starttext
\setlayer[hi]{hi}
\startTEXpage[offset=10em]
\null
\stopTEXpage
\stoptext
I don’t get the layer in the TEXpage.
How could I get it with the TEXpage dimensions?
only by first boxing (using framed or so) and then taking those dimensions
