Well, I think the idea is to create 360 PNG files, and
animate them by using something *other* than IDL to stitch
them into a movie. You can create your PNG files by doing
something like this:
FOR j=0,359 DO BEGIN
filename = 'file' + String(j, Format='(I3.3)') + '.png'
Write_PNG, filename, Reform(array[j,*,*],199,101)
ENDFOR
Cheers,
David
