# [pstricks] producing a sequence of Pstricks files

Hi Patrick,

PSTricks offers the _multido_ command to reproduce some different
graphics with animation character.

They are setup on multiple pages. If you scroll the pages you get the
imitation of an animation.

You can split the PDF pages and use them for other software to produce
an animation. pdf2swf or stuff.

I do not really understand the aim you have.

What is the advantage to have ONE TeX file per frame?  Isn't it easier
to have ONE TeX file for all the necessary frames and rework the
produced PDF?

animate package delivers the necessary commands to make an animation.
AcroTeX as well however distiller is needed to produce the necessary
layers for an animation.

What format for the frames is the wanted for your purpose?

Compile the following done with multido and then view the pages of the
resulting PDF.

Regards,

Juergen
