OK, in my case it seems that I don't need the  libQt*so under lib/. So I
have renamed it as _lib, and now xpdf runs ok.

The ubuntu package must be built incorrectly, for I have

That is what I get using mupdf (x11).

I found this comment:
"Copy-paste will only work if mupdf-gl is built against the bundled copy
of FreeGLUT, which adds the functions glutSetClipboard and
glutGetClipboard."

And, for example:

I'm wondering if there has been a regression in the rendering of
CJK recently? I'm attaching two screenshots from the same code:
one with lmtx-20210509 (correct); and the other lmtx-20210613
(incomplete).

This is what I have in the setups:

% Support for Japanese

\setscript[hanzi]

\starttypescript[serif][sourcehanserifregular]

\definefontsynonym[Serif][name:sourcehanserifregular][features={aalt,hist,kern,liga}]

\stoptypescript

\define[1]\JA{\language[ja]{{\setscript[hanzi]\sourcehanserifregular #1}}}



You can try to play with this font setup, all settings within the 
setups-block are applied when you change the language.



% font setup for english ...

\definefontfamily [source] [rm] [Source Serif]

\switchtobodyfont [source]

mupdf-gl (the advanced one) uses opengl,  but unfortunately it breaks 
when the drivers are updated;

mupdf uses x11, and it's much more stable.
To be honest, under ubuntu okular and evince are still better than mupdf.

Did you try this one?

(Not sure if we have a wiki page for viewers that keeps track of the 
quality.)

I was refereing to a textual copy, not an image one. So one selects

btw, When testing your example I noticed that sumatra pdf (which i use
as viewer) doesn't handle selecting the cjk text well. I looked at the
source (on github) and get the impression that it might be some font
bbox issue (these asian fonts have hugee bboxes); (also old) acrobat
and
browsers do fine as does an old windows okular I have installed.

Does anyone know of a minimalistic mupdf based pdf viewer that has a
decent gui but not all this (semi) epub, xps, reflow, etc stuff on
board? Just the mupdf pdf core.



perhaps the mupdf app for android.


the windows mupdf viewer is somewhat crippled (no selection) but 
searching for something shows the right bbox



Another one is  evince for windows:
https://portableapps.com/apps/office/evince_portable 

I tried it and it does the selection ok (but it's some 60MB so not lean 
and mean).


I also tried xpdfreader (some 30B) which also selects ok.

exit 2


indeed, my collegue does something like that (per project actually) and 
updates when things come out the same (or better or when some new 
feature is needed)



But really, taking things back a version or two isn't needed all that often
as issues tend to be sorted out quite quickly with all the testing that 
people

are doing -- so thanks for that too. :)


right, and thanks to that rapid feedback we were able to advance and 
cleanup the engine quite a bit as well as apply new features to context; 
without users that test and apply and demand new features there wouild 
be no development


thanks,

Hans

I uploaded a new lmtx ... kind of experimental because I changes some of 
the background bist that deals with embedding. The problem is that we 
need to deal with the previously reported clash between different 
unicode entries that share shapes (normally no issue but in this case it 
was a side effect of 'effective' monospaces where the font decided that 
invisible shapes should he visual anyway) as well as with the fact that 
soem cjk fonts have many duplicates which makes us cross the 65 boundary.


The variant approach is ok but I might have overlooked some soecial 
cases. Because this also drops 'stream compatibility' between mkiv and 
lmtx (which had already become somewhat loose) I can now also clean up 
(simplify) some other parts of the font system but let's do that 
stepwise (I'm in no hurry here).

[NTG-context] [#1] CJK regression? | lmtx-20210613 .

2021-06-13 Thread Richard Mahoney 
I'm wondering if there has been a regression in the rendering of 
CJK recently? I'm attaching two screenshots from the same code:
one with lmtx-20210509 (correct); and the other lmtx-20210613
(incomplete).

This is what I have in the setups:

% Support for Japanese

\setscript[hanzi]

\starttypescript[serif][sourcehanserifregular]

\definefontsynonym[Serif][name:sourcehanserifregular][features={aalt,h
ist,kern,liga}]

\stoptypescript

\definetypeface[sourcehanserifregular][rm][serif][sourcehanserifregula
r]

\define[1]\JA{\language[ja]{{\setscript[hanzi]\sourcehanserifregular
#1}}}


And this is the code behind the screenshots:

{\tfx
