[Scilab-users] Bitmap export

[Eduardo Torrecillas]

Hi Stefan,

I am experiencing pretty good results exporting pictures from Scilab as
EPS, using xs2eps().
After that, you can convert the pictures using the linux command convert
(if ImageMagick package is installed).
If you have a large number of pics, you can write a simple shell script to
do that too.

Best regards,
