i use a little work around to avoid the color problems with set_plot, 'ps'
pro tvgif, array, show=xview
sz=size(array)
xdim=sz(1)
ydim=sz(2)
window,31, /pixmap, xsize=xdim,ysize=ydim ; internal window, does not
; appear on the screen
tvscl, array
WRITE_GIF, 'tvgif.gif', TVRD() ;saves image in working directory
wdelete,31
if keyword_set(xview) then spawn, 'xv tvgif.gif'
return
end
usage:
tvgif, array, /show
if i set the keyword 'show' idl spawns xv where i can save my file in a
different format, print it etc...
