Hi all,
Can someone explain if there is a way to 'fix' the iTools problem
demonstrated in the code below. The problem is that the image plotted
in the iMap call does not export to a vector postscript cleanly
(File->Export->'To File'->myFile.eps). Instead of getting a white
masked area outside of the map projection, I get black in the eps file.
None of the bitmap outputs suffer the same. I've tinkered with the
CHANNEL and CLIP_PLANES keywords but was unable to make this go away :(
Any help is greatly appreciated.

pro test, NH=nh, SH=sh
xlon = 3*findgen(120) - 179.5
xlat = 2*findgen(90) - 89.5
field = sin(xlon/30) # cos(xlat/30)
; Default to plotting northern hemisphere
nh = 0 & sh = 0
if keyword_set(nh) then nh = 1
if keyword_set(sh) then sh = 1
if (nh + sh) eq 0 then nh = 1
idx_nh = where(xlat ge 0, COMPLEMENT=idx_sh)
if nh then idx_lat = idx_nh else idx_lat = idx_sh
; Plot it
iMap, field[*,idx_lat], xlon, xlat[idx_lat], $
