Excellent, thanks!

Do you happen to know whether anybody has ever done anything vaguely
similar that I can base this on, or would I be better off starting
from scratch?

Thanks!

[NTG-context] floatcombination boundingbox

2017-06-28 Thread Mikael P. Sundqvist 
Hi,

I wonder what is going on in the example given below (resulting pdf
attached)? The placement of the figures in floatcombination (this does
not happen if I place them one by one in a figure) are shifted
horizontally, and seems to depend on the boundingbox. Am I doing
something wrong?

This happens with current version: 2017.06.27 18:05 but also with a
version that is some weeks old.

Thanks, Hans!  I never expected it to work out of the box, and I'm
quite happy to do a lot of programming to make it work.

What I'd really like to know is whether the relevant parts of TeX have
been Luafied already (in which case I might do it soon), or whether

Perhaps it would be easier if I didn't think of it as a column, but
simply as a box?  The only problem I can see with that is that it
makes it awkward to handle the fact that long entries will often need
to run into the next column.

Re: [NTG-context] Problem with lucida fonts (again)

You're this guy, right?

https://tex.stackexchange.com/questions/338849

Sorry, but as last time, we can't help you without you posting a
reproducible example.  The
following works fine for me on TL2016, TL2017, and latest beta.

\setupbodyfont[lucidaot]

\starttext

\input knuth

\stoptext


Here is an exemple, I show size 30 to see the differences but the size 
doesn't change the behaviour.


\starttext
\setupbodyfont[30pt]
texte $math$

\setupbodyfont[lucidaot,30pt]
texte $math$

\setupbodyfont[lucida,30pt]
texte $math$
\stoptext


I join 2 pdf with an "old" version of context (texlive 2016) and the 
last stable.


You'll see that lucidaot has an effect, it uses cm fonts but without 
italic in math

lucida shifts lhe letters in text, not in math.
