Black screen movie [message #79597]

Dear all,

I'm a very beginner and would like to create a movie with IDL. I tried
therefore the following:

for i=0,n-1 do begin
filename ='DATA_000' +strtrim(i,2)+'.tab'

readdata,filename

iimage = tvrd(true=3)
xinteranimate,image=iimage,frame=i
endfor

Readdata is a program which creates (after some calculations) a
contour plot. However, when xinteranimate starts, the contour plot
appears correctly but not in the xinteranimate frame. Therefore, I get
a black screen movie. So, I think something is completely wrong...
The same problem happens if I use the 'addvideostream' command. The
contour plot seems to appear in a different window.
How can I "put" the contour plot which I call with Readdata into a
movie frame?

Thanks for any help,
Sofie
