Hi Hamish,
vlegend
where -100 0 --> future 100% 0%
ref right lower
font Monaco
fontsize 8
border 1
color black
fcolor white
end
The main change of my custom ps.map is to add a legend.h and legend.c to
manage the cosmetic rules of legend (vlegend and rlegend, it is colortable
[float or not]) with the rules: where, ref, offset, border, color, fcolor,
font, fontsize, fontcolor, cols (and span), margin and width (of the symbol).
Span is included with cols and negative values permit extend the legend over
the width of the map (-1 same width that the map, -0.5 the 50% of the width
and so)
Moreover, I want traslate more responsabilities of drawing to postscript (the
C code is reduced and the relative size of ps file); and to exploit the
resources of postscript drawing. Then re-write many part of vlegend, and new
rlegend as substitute of the files ps_clrtbl and ps_fclrtbl (but with same
parts of code as nice step and ordination of vectors to mantain same final
aspect of the map).
Also I try to all 'color' rules use named, RGB or none.
Well, three images with my custom ps.map in action:
vlegend.jpg is obtained with ...
vlegend
where 0% 0% -> now use percent (or absolute inches, of course)
ref left upper -> reference point
offset 0 -2 -> x and y offset in points
font Monaco
fontsize 8
fontcolor black -> new
margin 4 -> inner margin
border 2 -> width of outer border (<0 no border)
color black -> color of border (named, RGB or none)
fcolor 240:240:240 -> background color of vlegend (named, RGB or none)
cols 2 -0.5 -> cols and span in inches (<0 auto, here 50% width of map)
end
rlegend.jpg is obtained with ...
rlegend y
raster $RASTER
where 0% 100% -> use percent or...
ref left upper -> reference point
offset 0 0 -> x and y offset
border 2
color indigo
fcolor white
font Monaco
fontsize 8
fontcolor black
width 0.25
height 3
tickbar y
end
rlegend2.jpg is a not float colortable 
thanks,
Jorge
