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
