The code below creates strange results when turning on the cgm and the
land_fill. The colored areas get messed up. This is obviously related
to the clipping. When taking out the 'clip=0' in the call to map_set,
it all looks fine. And when plotting to e.g. the screen the problem is
not seen. Looks like a bug?
------------------------------------------------------------ ------------
PRO Maptest, cgm=cgm, fill_land=fill_land
IF KEYWORD_SET(cgm) THEN set_plot,'cgm'
loadct, 39
!P.color = 0
!P.background = !D.n_colors-1
;..map projection defined here:
P0lat = 90
P0lon = -32
minlat = 35
maxlat = 90
minlon = -20
maxlon = 60
map_set, P0lat, P0lon, /stereo, title = title, $
e_horizon = {fill:1, color:90}, $
limit = [minlat, minlon, maxlat, maxlon], clip = 0
IF KEYWORD_SET(fill_land) THEN BEGIN
map_continents, /countries, /coast, /overplot, /cont, $
/fill_cont, color = 170
ENDIF
;..draw the coast and border lines:
map_continents, /countries, /coast, /overplot, /cont
END

In the CGM driver!? Goodness! Even if you found a bug
(and I doubt it), the last time anyone looked at the
code in that driver was long before most of the current
programmers at ITTVIS were born! I'd set CLIP=0 and
be grateful the thing even works at all!
Cheers,
David
