Another potentially disruptive update: the raster library now uses
floating point values for coordinates.
Next update: the cairo driver is now the default, assuming that GRASS
was built --with-cairo. If you haven't been enabling this, now is the
time to try, as the PNG driver may not be around for much longer.
It's still possible to force the PNG driver to be used by setting
GRASS_RENDER_IMMEDIATE=PNG.
At present, it uses the "toy" font backend, which means that it only
understands a limited set of fonts (AFAICT, it understands mono, serif
and sans, and -bold and -italic variants), although support for
FreeType and stroke fonts will be added soon.
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
steadily
- 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.
