Re: Displaying an animation / "movie"

[Robert S. Weigel]

In Matlab I was never satisfied with the movies created using imshow.  I 
prefered the finer-grained control of using epstk to create 1 eps file per 
frame and then png2swf [http://www.swftools.org/] after converting .eps 
to .png with the ImageMagick command line program "convert" .  Using this 
method I am able to create full-screen movies without muddled text and lines. 
(Also, if I ever want to re-create a movie when typical monitors are 
16000x12000 pixels, I just need to run a script that operates on the 
vector .eps files and change the -density parameter.)

Here is my .m and shell script I use to automate the process:

for i = 1:99
FileName=sprintf('./figures/Figure_%03d.eps');
% postscript file creation commands
end

#!/bin/bash

DEN=200

cd ./figures
for k in $(ls *.eps); do
    echo "Converting $k";
    convert -density $DENx$DEN $k $k.png;
done
png2swf -o all_X_$DEN.swf -r 12 *.png
