Lower limit of integrals shifted

Lower limit of integrals shifted

[Mikael P. Sundqvist]

[-- Attachment #1: Type: text/plain, Size: 279 bytes --]

Hi,

the output of

\setupmathematics[
integral=nolimits,
]

\starttext
\startTEXpage[offset=2bp]
$\displaystyle\int_0^1x^2\,dx=\frac{1}{3}$
\stopTEXpage
\stoptext

is attached. Clearly, the lower limit in the integral is not correctly placed.

With hope of a quick fix,

Mikael

The problem is in the fonts ... some have proper math kerns, some don't, 
some have italic, some don't, so one solution for all is impossible

one way to deal with this is setting options (but these can be different 
per font and i'm not sure yet how to support that)

you can try if \mathnolimitsmode=3 works ok for you

will work ok for you

\startTEXpage[offset=2bp]
     $\mathnolimitsmode0    \displaystyle\int_0^1 x^2\,dx=\frac{1}{3}$\par
     $\mathnolimitsmode1    \displaystyle\int_0^1 x^2\,dx=\frac{1}{3}$\par
     $\mathnolimitsmode2    \displaystyle\int_0^1 x^2\,dx=\frac{1}{3}$\par
     $\mathnolimitsmode3    \displaystyle\int_0^1 x^2\,dx=\frac{1}{3}$\par
     $\mathnolimitsmode4    \displaystyle\int_0^1 x^2\,dx=\frac{1}{3}$\par
     $\mathnolimitsmode2000 \displaystyle\int_0^1 x^2\,dx=\frac{1}{3}$\par
\stopTEXpage

Oh, that sounds bad if it is in the fonts (I don't understand, it
seemed to work fine with lmodern, stixtwo, lucidaot, ... just before,
has something changed recently?)

Two related questions:

1) This \mathnolimitsmode does not seem to have any effect in a
\startformula \stopformula.
2) Could one set this globally (both inline and displayed formulas) in
a document?

well, then always enable mode 3 ... the default to mode 0 is because 
fonts can have kerns to deal with this but anyone can choose his/her 
preference ... as said, i'm nto sure hot to deal with it in context (as 
i might as well decide to add proper kerns to these fonts at runtime)

you can try something

\appendtoks ... \to \everymathematics

(i might cook up some more granularity in the future - i have some ideas 
about it - but that will then be experimental for a while)

special book layout problem in ConTeXt

[Nicolas Mondon]

[-- Attachment #1.1: Type: text/plain, Size: 872 bytes --]

Dear ConText Hepers,

I'm not sure I'm writing at the good email adress, or even the good 
place; but sorry, I didn't find any online forum or othr hep centers, so 
I try. Please tell me if I have to write to someone else.

I'd like to edit a thesis (so, as a book), with the text only on even 
pages, and tables and figure only on odd pages, in front of the 
paragraph wich comment them. I try to do this automatically by writing 
the text, make a reference to the figure in the paragraph, and then the 
layout appears correctly...

I have the impression this is possible to do in ConText, but I havn't 
find how yet. Is it possibel to force, in the setups, the text to be on 
the right pages, and the figures on the left pages?

Thank you very much in advance

All the best

Nicolas Mondon

If the figures/tables should appear before the text you want on a even 
(left side) page while the text would appear only on odd (right side) 
pages. A few questions remain before a certain answer can be given, e.g. 
should the left page be empty when there are no figures/tables for the 
following right page and should the float appear at the same vertical 
position as the reference.

There is no easy solution for this yet and it also depends on your 
requirements mentioned above. The easiest way to achieve such a layout 
is to to increase the paper width to twice the normal layout and use the 
left half for a very big margin area where you can place the 
tables/graphics.

In a first step you create a normal document with this unusual layout. 
Afterwards you split each page in half and create two separate pages 
from one single page which can be done with a loop (can be done 
theoretically with the imposition mechanism but a separate document is 
easier).

Wolfgang

Wouldn’t it make sense to use streams (https://wiki.contextgarden.net/Columns#Streams)?

Re: special book layout problem in ConTeXt

[Nicolas Mondon]

[-- Attachment #1.1: Type: text/plain, Size: 3205 bytes --]

Thank you Wolfgang for your answer.

So, yes the figures/tables should appear before the text on a even (left 
side) page while the text would appear only on odd (right side) pages. 
The left page should be empty when there are no figures/tables for the 
following right page, and the float doesn't have to appear strictly at 
the same vertical position as the reference, but as possible only. 
Specially beacause, it may have several references in only one paragraph 
for exemple on the right page, and so the figure should appear in the 
right order on the left page, but couldn't be exactly at the same 
height. Also, if there are too many references in on right page, the 
figures which can't fit the left page should go on the top od the next 
left page...

It's possible that my answer change the proposition you made at the end 
of your message. Nevertherless, there is some thing in your last 
paragrph which is not clear for me : " Afterwards you split each page in 
half and create two separate pages from one single page which can be 
done with a loop (can be done theoretically with the imposition 
mechanism but a separate document is easier)."

Thank you!

Step 1:

  Create a document with a very big left margin where you can place all 
floats.

\setuppapersize
   [A3,landscape]

\setuplayout
   [backspace=23.5cm,
    width=15cm,edge=14cm]

\showframe

\setupfloat
   [default=leftedge,
    minwidth=14cm]

\starttext

\input ward

\startplacefigure
\externalfigure[dummy]
\stopplacefigure

\input knuth

\startplacetable
   \starttabulate[|c|c|c|]
   \FL
   \NC A \NC B \NC C \NC\NR
   \ML
   \NC X \NC Y \NC Z \NC\NR
   \LL
   \stoptabulate
\stopplacetable

\input zapf

\stoptext


Step 2:

Split each page into two separate pages where one contains all floats 
while the other page contains the text.

Wolfgang
