Hi, I'm trying out the new Cairo driver. To make things easier I just added support for it to d.out.file: use the -c flag with a raster image format.
As AFAICT there is no user documentation, so I also added a small wiki page for it: http://grass.gdf-hannover.de/wiki/Cairo_driver It is missing a display/drivers/cairo/description.html page, modeled after the equivalent PNG driver page. There's a problem in that the raster data is being rendered offset vs. the vector data. For a window with the same aspect ratio as the region it seems to line up ok. Else, not. e.g. export GRASS_WIDTH=720 export GRASS_HEIGHT=585 d.mon x0 d.rast map=elevation.10m d.vect map=streams width=1 color=blue d.vect map=roads width=2 d.out.file -c sf_cairo format=png size=800,800 # even more dramatic d.out.file -c sf_cairo1 format=png size=400,800 d.out.file -c sf_cairo3 format=png size=800,400 ? example: http://bambi.otago.ac.nz/hamish/grass/bugs/sf_cairo1.png There's another problem with fonts- True/FreeType fonts gets scrambled. This reminds me of a long ago bug in d.text.freetype, fixed in rev 1.42. "use correct pitch for reading bitmap buffer & fix scrambled letters" http://freegis.org/cgi-bin/viewcvs.cgi/grass6/display/d.text.freetype/main.c example: http://bambi.otago.ac.nz/hamish/grass/bugs/sf_cairo2.png (d.* commands given on the above wiki page) Hamish _______________________________________________ grass-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-dev
