Hi,
I have been trying to overlay an IDL image on google earth, and it
worked pretty well. One thing that would be really useful is to have
IDL do a contour plot without introducing an extra border to the image
(so I can directly import it in google earth). I have tried setting
the position and region variable to [0,0,1,1], but to no avail. The
extra border I am talking about can be seen here:

I am referring to the very thin black border between the image and the
thin white boarder (not the thick black border).
Here is a minimal example
DEVICE, DECOMPOSED=0 & window,1,xsize=5000,ysize=2500
MAP_SET, /Cylindrical , LIMIT = [-90, -180, 90, 180], Position=[0, 0,
1, 1]
contour, zzzz, lond,latd ,/OVERPLOT,Position=[0, 0, 1, 1]
MAP_CONTINENTS, Position=[0, 0, 1, 1] & Map_Grid, Position=[0, 0, 1,
1]
Any help much appreciated!
