Can anyone tell me whether it is possible to generate an mpeg or fli format
animation files from IDL. If not in IDL then is it possible to do this
externally - ie using another piece of software.
Anyone who has done this or has any information about this, please contact me.
Thanks in advance.
Matt

Hallo Matt!
I think I have something You can use to do this job.
A few years ago I wrote a x_movie.pro, which allows to read images
of all image-formats supported by IDL and to animate them.
Instead of animating them You can convert them to all image-
formats IDL knows. A few formats are included by myself,
because IDL doesn't know FLI and SunRasterFiles with compressed
mode. FLI is only in an input mode, but when You read the part
of x_movie.pro which is reading the FLI-image, You will surely be
able to write FLI-Files by Yourself.
Another method could be to take the XFLICK-Tool, which allows to
visualize weather-cards (i.e from Edinburgh) in fli-Format. By the
help of Michael Pall from University of Karlsruhe (Germany), I got
a deflick-Tool, which is able to separate each image in a fli-movie
on a single file. In XFLICK and DEFLICK You will find C-routines,
which allow to access FLI-image-Files (WRITE/READ). But I use all
of them a few years ago and only for a short time. I am not an
expert on this area.
If You are interested in this tools, please send me a mail.

I tried something simular a few days ago. You should make use of the
WINDOW keyword in XinterAnimate. This copies the entire contents of an
existing window to a frame for the animation. Here a short example where
I assume the ImageSeq is a 3D matrix containing the sequential data.
************************************************************ ******************
Pro Animate
Z=100 ;Number of images
Window, /Free, xs=300, ys=300 ;Create a window to hold the image in.
;You could set the /PixMap here to not even
;show the window.
WinID = !D.Window ;Get the ID of this Window
Xinteranimate, Set=[300,300,Z] ;Setup Xinteranimate. The 300 here
should ;correspond with the x and y size of WinID
For I=0, Z-1, 1 do Begin ;Start the loop
Wset, WinID ;Make WinID active. Not really necessary in ;this
example.
; Create a shaded surfaceplot which will be displayed in the active
Window.
; You can of course put here any plot or image that can be dislayed in a
Win.
shade_surf, ImageSeq(*,*,i), shades=ImageSeq(*,*,i),$
AZ=300, xstyle=4, ys=4, zs=4, Zrange=[0,250]
;Load the complete contents of the window in Xinteranimate.
Xinteranimate, Frame=i, Window=WinID
endfor ; End of the loading loop
Xinteranimate, /Keep_Pixmaps ;Show the animation and keep the images
for ;further use.
END ; of Animate
************************************************************ ******************
Hope this gets you on the way. It made my boss enthousiastic to see the
animation so I hope it will make yours also jump. Be sure to use fancy
colors!:-)
Greetings, Armand.

This kind of thing is easily done with XInterAnimate, since
this program can take a "snap-shot" of whatever is in the
current graphics window. With a surface plot, the only
tricky thing is to make sure IDL is not autoscaling. If
you allow autoscaling of axes, the surface will be "jumping"
in the animation, which you don't normally want.
Suppose I had 10 data files named data0.dat to data9.dat
containing 40 by 40 floating point data that I want to
animate. And suppose I know that the maximum value in
all 10 of these data sets is 1500 meters. My code to
animate this data might look like this:
; Set up XInterAnimate
XInteranimate, Set-[300, 300, 10], /Showload
; Open the data sets. Put surface plots in the
; XInterAnimate window and take a snap-shot of them.
FOR j=0,9 DO BEGIN
filename = 'data' + StrTrim(j,2) + '.dat'
OpenR, lun, filename, /Get_Lun
thisSurface = FltArr(40,40)
ReadF, lun, thisSurface
Free_Lun, lun
Surface, thisSurface, ZRange=[0,1500], XStyle=1, $
YStyle=1, ZStyle=1
XInterAnimate, Frame=j, Window=!D.Window
ENDFOR
; Run the surface animation.
XInterAnimate
Cheers,
David
