Cairo driver

Cairo display driver

(under development)

• Cairo homepage

based on this grass-dev thread:

http://thread.gmane.org/gmane.comp.gis.grass.devel/22786

To compile GRASS 6.3 with Cairo support, make sure you have the cairo.h include file (in Debian/Etch it's in the libcairo2-dev package)

Then build grass with:

make USE_CAIRO=1

Examples

Example using the driver directly:

export GRASS_TRUECOLOR=TRUE
export GRASS_CAIROFILE=spearfish.png
export GRASS_WIDTH=800
export GRASS_HEIGHT=800

d.mon start=cairo
d.rast map=elevation.10m
d.vect map=streams width=1 color=blue
d.vect map=roads width=2
d.mon stop=cairo

Example using d.out.file:

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
