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]

drawarrow p withcolor black ;
\stopreusableMPgraphic
\startreusableMPgraphic{canaux}
path p; p:= (0,0) -- (20,0) ;
drawarrow p withcolor \MPcolor{canaux} withpen pencircle scaled 2pt;
\stopreusableMPgraphic

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 ?
