Hi all,
Today I send to repository grass-addons a new program to draw maps in
postscript-3. The program is similar to ps.map but I prefer no overlap this
standard package until ps.output work fine (or never).
ps.output has many differences with ps.map
- the multilevel structure of the script, for example
font
name Univers
size 10 (or 3mm)
color black
extend 0.8 (condensed, or 1.2 to extended)
end
-all colors are RGB or named
- raster is expanded to
raster one raster, one group name or three raster (RGB)
grey [y|N]. Output in shades of grey.
maskcolor [color]. Color to be used for mask.
maskcell [R (R)]. Raster mask and optionally a raster background.
outline [line]. Specifications of outline.
setcolor [cat color]. Overrides the color of cat
end
- now the legends (rlegend or vlegend) has a title, frame, ...
- rlegend permit reorder the data (need improved)
- vlegend work perfectly with multicolumn categories (I test more than 1000
categories and work 
- vector lines can draw as area (with vareas) of a width (positive or
negative). Interesting to coast lines, beach, ...
- five types of scalebar with subscale at zero left
- draw (including rose) in a specific command
- and more
ps.output is not full finished. For example TODO there is a error drawing the
geogrid in south hemisphere, new palette command dont work in gradient
subcommand, I want better vlegend options, helo is incomplete, etc but the
standard command work fine. However, it is necessary a testing for bugs or
mistakes. Please, send me any improvement or bugs that you find.
I attach a PDF example (from GRASS data 'nc_spm_08') with raster options,
outsize border and the text of the script to make it. (Sorry by the
aesthetic, but the colors are for testing

To Hamish,
so instead of automatically removing it gives you the option?
Grid command has a round option equivalent to the number of trailing-zero to
cut, but don't cut if there is a minor number of zeros (the work as in
ps.map). For example,
major 50000 and round 3 -> draw a grid with numbers 4700 4750 4800 ...
but
major 50000 and round 7 -> draw 470 475 480 ...
ideas!
I'm blocked with the IHO text numbers (ps.output don't draw). In the
horizontal lines could be 4750/000 (metres below) or 4ºN/23.23' (minutes
below) but how can I draw in vertical lines? Any idea?
