Re: [NTG-context] Equivalent of alignat of amsmath with context
Hi Fabrice,
I think you have to use
\startalign[n=3,align={left,right}]
and finish the alignment with
\stopalign
Is this what you are looking for?
\starttext
\startformula
\startalign[n=3,align={left,right}]
\NC \qquad \NC\frac{\lvert\overline{AD}\rvert}{\lvert\overline{CD}\rvert}
\NC =\frac{\lvert\overline{DC}\rvert}{\lvert\overline{CE'}\rvert}\NR
\NC \iff \NC \frac{1}{x} \NC =\frac{x}{1-x} \NR
\NC \iff \NC 1-x \NC =x^2 \NR
\NC \iff \NC 0\NC =x^2+x-1 \NR
\stopalign
\stopformula
\stoptext
Best regards: OK

[NTG-context] placing an MPGraphic/Lines over multiple table cells
I am trying to place some lines in "Z" shape over several cells of a
table. This single "Z" has the intention of blocking manual alterations
to the table in empty cells. The cells to blocked are always a coherent
rectangle. I hope that makes sense.
In the example below, the table with 4 rows, 3 columns has content in
column one only, the other 2 columns should have the "Z". Placing the
blocking "Z" into every cell is not an option due to formal
requirements.
What I attempted below a) seems very cumbersome b) doesn't work (the
small "Z" doesn't fill the frame).
While I can easily place a "Z" into a single cell (in the example), I
can't figure out how to cover multiple cells. Furthermore, I would need
to do a lot of calculations to figure out the multiple layer placements,
column positions, etc. With multiple tables on a page, several pages,
that seems error prone.
Any suggestions, corrections, hints are most welcome!
Kindly, Martin
Working example with some comments:
% Graphic that draws the "Z", that works fine in a single table cell as
seen in the example
\startuseMPgraphic{ZRule}
rulethickness:= \frameddimension{rulethickness}*3;
drawoptions(
withpen pencircle scaled rulethickness
withcolor \MPcolor{\framedparameter{framecolor}});
pair topleftcorner, toprightcorner;
topleftcorner := (rulethickness, \overlayheight-rulethickness-1.5mm);
toprightcorner:= (\overlaywidth-rulethickness,
\overlayheight-rulethickness-1.5mm);
pair lowerleftcorner, lowerrightcorner;
lowerleftcorner := (rulethickness, rulethickness+1.5mm);
lowerrightcorner:= (\overlaywidth-rulethickness, rulethickness+1.5mm);
draw topleftcorner -- toprightcorner;
draw lowerleftcorner -- lowerrightcorner;
draw toprightcorner -- lowerleftcorner;
\stopuseMPgraphic
\defineoverlay[ZRule][\useMPgraphic{ZRule}]
\starttext
\setupTABLE[c][each][width=30mm]
\setupTABLE[r][each][width=6mm]
% in an attempt to place the table at known positions, I put it into a
layer. Though it is not really "background".
\definelayer[datatable][x=0mm, y=0mm,width=\textwidth, height=25mm]
\setlayer[datatable][hoffset=0mm, voffset=0mm]{
\bTABLE
\bTR
\bTD content1 \eTD \bTD \eTD \bTD \eTD
\eTR
\bTR
\bTD content \eTD \bTD \eTD \bTD \eTD
\eTR
\bTR
\bTD content \eTD \bTD \eTD \bTD \eTD
\eTR
\bTR
\bTD content \eTD \bTD[background=ZRule] \eTD \bTD \eTD
\eTR
\eTABLE
}
% Now trying to create another layer covering the table area where the
"Z" should go.
\definelayer[ZStrike][x=32mm, y=0mm,width=60mm, height=24mm]
% The "Z" fails to reach full size of the frame
\setlayer[ZStrike][hoffset=0mm,
voffset=0mm]{\framed[frame=on,width=60mm,height=24mm]{\useMPgraphic{ZRule}}}
% arrange the "background" layers
\setupbackgrounds[text][background={datatable,foreground,ZStrike}]
\blank[force, 28mm]
further content
\stoptext
