Hello,
I am still working on maps and facing some new issue.
The program I used to design one map is not convenient for writing key
to symbols, and what I have is a map.png file with big spare space on
its upper left corner.
So I have either to write on the png with ImageMagick or GIMP,
or have a nicer output with ConTeXt.
I wrote this legend file.
\definecolor[canaux][h=81b3e0]
\startreusableMPgraphic{voies}
path p; p:= (0,0) -- (20,0) ;
drawarrow p withcolor black ;
\stopreusableMPgraphic
\startreusableMPgraphic{canaux}
path p; p:= (0,0) -- (20,0) ;
drawarrow p withcolor \MPcolor{canaux} withpen pencircle scaled 2pt;
\stopreusableMPgraphic
\startbuffer
\bTABLE[frame=off]
\setupTABLE[column][1,3][align={middle,lohi}]
\bTR
\bTH 1) \eTH \bTH Le milieu \eTH \bTH 2) \eTH \bTH Les activités \eTH
\eTR
\bTR
\bTD \externalfigure[illustrations/zone_urbaine][height=12bp] \eTD \bTD zones urbaines \eTD
\eTR
\bTR
\bTD \leavevmode \reuseMPgraphic{voies} \eTD \bTD infrastructures~: voies ferrées \eTD
\eTR
\bTR
\bTD \leavevmode \reuseMPgraphic{canaux} \eTD \bTD infrastructures~: canaux \eTD
\eTR
eTR
\eTABLE
\stopbuffer
The idea was to make some
\hbox{
\externalfigure[map][width=0.9 \textwidth]
\vbox{\hfill -0.9 \textwidth
\getbuffer
}
}
to put the boxed legend at this upper left corner.
Of course I couldn't succeed, since I do not understand so much
boxes. ConTeXt complains with a missing number.
How could I achieve such boxing ?
Thanks,
Damien Thiriet

Thank you very much Hans !
One of my first thoughts today was using layers (did not think about
it earlier, because I was too focused on plain TeX boxes), but I am
quite new to this topic.
Thanks to your code, I will have time to learn how to use them.
Greetings,
Damien Thiriet
