Another way to see it is just zoom in on the PDF. If the artifacts go away on 
zooming in, then they are due to anti-aliasing.

It's whatever ConTeXt standalone has. I don't have any extra Lua installed:

Typing lua gives command not found and texlua is system one.

anyhow, so what you see (in the file) is (per line) transform matrices 
that are slightly different so what you then see is rounding to the 
device pixels



Should I see it on non-HiDPI as well? Because it seems it's there.

i wouldn't loose sleep over it .. nowadays fonts also evolve and that 
gives larger differences

[NTG-context] LuaTeX and PDF.js

2021-01-07 Thread Vedran Miletić 

Hello,

I compared latest ConTeXt standalone (LuaTeX 2.08) against TeX Live 2020 
(LuaTeX 1.12). The produced PDFs are:


https://miletic.net/lipsum-112.pdf
https://miletic.net/lipsum-208.pdf

Viewing them with Evince (and I assume Adobe Reader, I don't have it at 
hand to test) shows only minor differences in (horizontal) character 
spacing, which I would expect; the text looks reasonably good either 
way. However, viewing them with PDF.js shows a large difference:


https://miletic.net/lipsum-pdfjs-112.png
https://miletic.net/lipsum-pdfjs-208.png

As you can observe, b, m, n, p, and r (and possibly others) are moved 
slightly above other letters. Is this the expected behavior? If not, is 
this an issue with the way PDF.js is displaying the PDF or the way 
LuaTeX is producing it?


Thanks in advance.

Regards,
Vedran Miletić

depends on what you consider (non) hdpi ... the positioning of glyphs 
depends on font scale, rounding of stems and such (hints in fonts but 
these get less relevant with high res displays), caching, inter glyph 
corrections (that pdftex/luatex/...) put in the text stream to resync

Re: [NTG-context] styling part of an index entry

2021-01-07 Thread Jairo A. del Rio 
Hi. In latest LMTX (2021.01.07 16:59), your example works as expected:

\defineregister[myindex]

\defineprocessor[style][style=italic]%Isn't another name available?

\starttext

In \myindex{style->Observer, The}{\em The Observer} of 31 July 2018

\placemyindex%

[NTG-context] styling part of an index entry

2021-01-07 Thread jbf 
I'm wondering if further progress has been made in Mk IV on styling 
parts of an index (register) entry? I have followed the explanation on 
the wiki, but do not seem to be able to achieve what I need.


And what I need is to be able to italicise entries that refer to 
newspaper names, e.g. The Observer


MWE

\defineregister[myindex]
\defineprocessor[style][style=italic]

\starttext

In \myindex{style->Observer, The} {\em The Observer} of 31 July 2018

\stoptext

The only result I am getting is:

->Observer, The   223

But what I want is /Observer, The/ (in other words, in italics).

Clearly I am doing something wrong, or not enough, or... maybe there is 
another way to achieve waht I need?

Re: [NTG-context] LuaTeX and PDF.js

2021-01-07 Thread Hans Hagen 

On 1/7/2021 10:10 PM, Vedran Miletić wrote:

Hello,

I compared latest ConTeXt standalone (LuaTeX 2.08) against TeX Live 2020 
(LuaTeX 1.12). The produced PDFs are:


https://miletic.net/lipsum-112.pdf
https://miletic.net/lipsum-208.pdf

Viewing them with Evince (and I assume Adobe Reader, I don't have it at 
hand to test) shows only minor differences in (horizontal) character 
spacing, which I would expect; the text looks reasonably good either 
way. However, viewing them with PDF.js shows a large difference:


https://miletic.net/lipsum-pdfjs-112.png
https://miletic.net/lipsum-pdfjs-208.png

As you can observe, b, m, n, p, and r (and possibly others) are moved 
slightly above other letters. Is this the expected behavior? If not, is 
this an issue with the way PDF.js is displaying the PDF or the way 
LuaTeX is producing it?
what lua does your 2.08 have? if it's 5.2. then such small differences 
can be a side effect of lua (different number models), serialization of 
numbers (default accuracy), or maybe rounding in the lua=>tex font 
interface (there were some fixes iir), the number of digist that the 
backend uses, etc


anyhow, so what you see (in the file) is (per line) transform matrices 
that are slightly different so what you then see is rounding to the 
device pixels


i wouldn't loose sleep over it .. nowadays fonts also evolve and that 
gives larger differences

It works here but i have different code in the meantime. We're in a
