Thanks Dylan,
No completely vector-based, obiously the raster map is a bitmap, but all lines
and the green area with transparent color are vector based. I send you a
screen snapshot of a 400% KPDF magnification (this attach with grey n, see
below) to test quality.
For the moment ps.output is a grass-addon different of ps.map but trying to
retain similar script files. For example, to draw the attached map the kernel
code of the script is:
ps.output -g out=$OUTPUT.ps << EOF
[... paper, grid, maparea, not commented -- in general just in
grass-addons ...]
raster 30m.3d@bierzo <- raster in the main area (dark gray)
grey y <- draw raster in greyscale (this attach N)
maskcolor 200:200:200 <- tint of the raster background (outside main area)
maskcell mask@bierzo 30m.3d@bierzo <- mask of main area and raster for
background (here the same as the main area)
end
vareas cs_lim@bierzo <- vector map of the green area
line <- style of the limit line of the area
width .1mm <- line width
color none <- no color = no line
end
fcolor 0:130:0$.5 <- fill color 0:130:0 = green, .5 = transparent 50%
end
vpoint bz_lim@bierzo <- boundary of main area (El Bierzo, spanish region 
type boundary <- this is vpoint but use along boundary
symbol basic/circle <- symbol to repeat
line <- style of the line of the symbol
width .3mm
color black
end
fcolor yellow <- fill of the symbol
size 3.5 <- scale of the symbol
dist 20 <- separation between symbols (for the moment, points)
cline <- style of the conection line
width .3mm
color black
end
end
vpoint meteo@bierzo <- vpoint type point (default)
symbol basic/circle
line
width .3mm
color black
end
fcolor red
size 3
end
EOF
Many new features are just in grass-addons ps/ps.output with new styles of
grids, etc.
The new features are not in grass-addons because I am testing and cleaning the
code for transparent colors (all colors are named or red:green:blue$alpha
colores -lines, areas, patterns, symbols, etc), and for symbol along lines (I
develop the code in the last 2 days).
All new ideas to improve the postscript output of GRASS are wellcome.
The idea of symbol along lines if from the INT1: "symbols, abbreviation and
terms used on charts" of the Organisation Hydrographique International -- to
can draw their area limits, railways, overhead transporter, dykes...
Very Nice work. Is this an extension to ps.map, or something new? Can
you elaborate on the intermediate format-- is it completely
vector-based?
Cheers,
Dylan
