\mframed not aligned in mkiv

\mframed not aligned in mkiv

[-- Attachment #1: Type: text/plain, Size: 824 bytes --]

Dear Hans,

I noticed a difference between mkii and mkiv in the behavior of \mframed: it seems that in mkiv the frame is not vertically aligned with the the + sign in the following example (or rather it is not vertically centered, please see the attached PDF produced with ConTeXt  ver: 2013.10.15 13:52 MKIV). 
Does one have to use now a new key to require this sort of alignment?

Best regard: OK

%%%% begin mframed-example.tex
\setupcolors[state=start]

\def\graymath{\mframed[frame=off,
   background=color,
   backgroundcolor=lightgray,
   backgroundoffset=2pt
   ]}

\starttext

Since for $|x| < 1$ we have
\startformula
\log(1+x) = \graymath{x- \displaystyle{x^2\over2}} + {x^3 \over 3} + \cdots
\stopformula
we may write $\log(1+x) = x + O(x^2)$.

\stoptext
%%%% end mframed-example.tex

Search for "Alignment in inmframed" in the mailing list archives.

% The next statement is part of the core. Included it here for 
% illustration.

\definemathframed[mcframed] [location=mathematics]

\starttext

\startformula
     \ln (1+x) = 
\mcframed[background=color,backgroundcolor=red,foregroundcolor=white,frame=off]{x 
- {\frac {x^2}{\frac{x^3}{\frac{x^3}{3}}}}} +
\frac{x^3}{3}-\cdots.
\stopformula

\startformula
     \ln (1+x) = \mcframed{x - {\frac {x^2}{\frac{x^3}{\frac{x^3}{3}}}}} + 
\frac{x^3}{3}-\cdots.
\stopformula

\stoptext

Thanks Aditya!
I overlooked this change in mkiv…

Best regards: OK

Re: \mframed not aligned in mkiv

[Otared Kavian]

Hi Aditya,

I wikified your remarks,

	http://wiki.contextgarden.net/Math/Display#Shaded_background_for_part_of_a_displayed_equation

but unfortunately the snippet of code does not compile on ConTeXt Garden: is there a way to typeset mkiv code there?

Best regards: OK

Rather than

\def\graymath{\mframed[frame=off,
     background=color,
     backgroundcolor=gray,
     backgroundoffset=3pt]}

you can just use:

\definemathframed[graymath]
    [
      frame=off,
      location=mathematics,
      background=color,
      ...,
    ]

This way, you can even override the options when using \graymath:

\graymath[backgroundcolor=red]{...}

> but unfortunately the snippet of code does not compile on ConTeXt Garden: is there a way to typeset mkiv code there?

Using <context mode="mkiv"> compiles the coding using MkIV, but 
contextgarden uses a rather old version of mkiv, so it is unlikely that a 
feature introduced a few months ago will run on the garden.
