I did exactly what you describe using pixmaps on a sun running
openwindows. The steps I used for each image were:
1) read the image from the data file
2) map_set,...
3) warp=map_image(img,xx,yy,...)
4) tv,warp,xx,yy
5) map_grid,/label
6) map_continents,...
7) plot other data, labels etc on plot
8) transfer the image to pixmap memory using TvRd() etc.
Once all the frames are ready, then I run a short loop to
display the frames (use: device, copy=...) while checking
the keyboard for input to freeze the animation, exit, etc.
A description of the pixmaps is in the IDL Reference Guide,
chapter on IDL Graphics Devices, under the section on the X
Windows Device.
Good Luck.

using xinteranimate, you can animate anything that you can display
in an X window. Under the widgetlib on-line help, you can check
out xinteranimate. Basically it is like
window,/free
win_number = !d.window
xinteranimate, set=[!D.x_size,!D.y_size,Nframes]
for f=0,nframes-1 do begin
; plot the stuff you want in window perhaps like
; map_set, 0,180,/cyl,/cont
; contour, data, lat, lon, /over
;
; then
;
xinteranimate, frame=f, window=win_number
endfor
xinteranimate
