Hi I have a 3D array, Image=[time,dimension_x,dimension_y]
I wrote the following code
for i=0L,n-1 do begin
im = reform(image[i,*,*])
im = BYTSCL(im, max=200.)
write_gif, im, file, /multiple
endfor
write_gif, file, /close
and I got this error: WRITE_GIF: Image must be a byte matrix. I used the BYTSCL function to convert my array to byte matrix but seems I am doing something wrong. Can anyone help?

Check the order of your arguments. You have them reversed, it looks
like.
Cheers,
