Hi Fabrice,

I have this from former exchanges

% Cancel command for use in equations.
\startuniqueMPgraphic{cross out}
 picture cross;
 cross := image(draw (0,0)--(1,1); draw (0,1)--(1,0););
 draw cross xscaled \overlaywidth yscaled \overlayheight withpen pencircle
scaled .8pt ;
\stopuniqueMPgraphic

\defineoverlay[canceloverlay][\uniqueMPgraphic{cross out}]

\define[1]\cancel{%
 \ifmmode
 \mframed[background=canceloverlay, frame=off, offset=overlay]{{#1}}%
 \else%
 \framed[background=canceloverlay, frame=off, offset=overlay]{{#1}}%
 \fi%
}

Maybe something else is available nowadays.

I don't know what the cancel package gives, but since December 22 or
so, one can do

\starttext

\setupframed
[mathstrikeout]
[color=darkgreen,
backgroundcolor=darkred,
frame=off]

\startTEXpage[offset=4dk,align=flushleft]
\dm{1+\mathstrikeout[strike:text={what is this?}]{(2x-x)}+2=3+x}
\blank
\dm{1+\mathstrikeout[strike:math={=x}]{(2x-x)}+2=3+x}
\blank
\dm{1+\mathstrikeout[strike:math=u,arrow=no]{(2x-x)}+2=3+x}
\blank
\dm{1+\mathcrossout[strike:math={=x}]{(2x-x)}+2=3+x}
\stopTEXpage

\stoptext

/Mikael

[NTG-context] Equivalent of the \cancel command with conTeXt

[Fabrice Couvreur]

[-- Attachment #1.1: Type: text/plain, Size: 199 bytes --]

Hi,
In an algebraic expression, it is sometimes interesting to cross out terms.
With LaTeX, there is the \cancel command from the package cancel. Is there
an equivalent with conTeXt ?
Thanks
Fabrice

Hi Mikael,
Thank you for this command ; there must be many others that I don't know
how they work.
