Subject: colored backgrounds in displayed math
Date: Thu, 09 Apr 2009 07:34:03 -0600 [thread overview]
Message-ID: <E1LruOK-0004L2-7e@approx.mit.edu> (raw)
In displayed math I was trying to highlight a piece of a formula using a
gray background. After a few spacing failures with \framed, I
discovered \mframed in the core-rul.tex source file. The comments there
say:
%D As usual, one can specify in what way the text should be
%D framed. One should be aware of the fact that, inorder to
%D preserve the proper spacing, the \type {offset} is set to
%D \type {overlay} and \type {frameoffset} is used used
%D instead.
But I couldn't get the following example of setting frameoffset to
enlarge the box; instead the gray box barely surrounds the x^2/2. Is
the cause the \@@oioffset in line 1502 of core-rul.tex:
[\c!frameoffset=\@@oioffset,\c!offset=\v!overlay,#2]
(I'm using ConTeXt - 2008.10.31 13:58, Mk II)
\setupcolors[state=start]
\def\graymath{\mframed[frame=off,
background=color,
backgroundcolor=gray,
frameoffset=5pt]}
\starttext
\startformula
\ln(1+x) = \graymath{x- \displaystyle{x^2\over2}} + \cdots
\stopformula
\stoptext
