[GRASS-user] Looping in GRASS GUI and accessing GUI monitor from command line

[Markus Metz]

Hi Ralf,

the script you use draws all raster maps on the same monitor using the
current region extents. That means that the next d.rast command will
draw a new raster map on top of the raster map of the previous d.rast
command. If all raster maps have identical extents, you will in the
end only see the last map drawn.

You can
1) draw each raster map in its own monitor
2) divide the monitor in frames and put each raster map in its own frame
3) use the GUI (tcl/tk or wx) and manually add all your raster maps to
the layer manager, then (de-)activate the maps as needed. The order in
the layer manager reflects the order of drawing, i.e. the topmost map
will be drawn on top of all other maps.

HTH,

Markus M
