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.

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 ?
