Seems to work great on the command line (aside a few questions below),
however, there seems to be problems in the guis:
- tcltk gui (gis.m): I cannot display any vector maps; raster map
display becomes very slow when zooming out, with memory usage rising
- wxpython gui: I can display vector maps, but as soon as I ask not to
display centroids, nothing is displayed at all
And here a few questions:
- How do I configure which format the cairo driver writes to (i.e. other
than PNG) ? GRASS_CAIROFILE doesn't seem to work:
GRASS 7.0.svn (nc_spm_06):~ > export GRASS_CAIROFILE=map.ps
GRASS 7.0.svn (nc_spm_06):~ > d.rgb r=blend.r b=blend.b g=blend.g
cairo: collecting to file: map.png
- How to tell it to read from an existing file ? Again, GRASS_CAIRO_READ
doesn't seem to work.
