- Yes, but it depends somewhat on your environment. I've
- written files like that and the old Preview on the NeXT
- would display them the way I wanted, but most would cache
- all the stuff up and wouldn't display it in real-time.
-
- You can make a "flip book" by making each frame a page and
- putting in the proper DSC for each. Then you can flip it on
- the screen with a previewer.
-
- Usually, you'd want to do the display part in PostScript
- and the timing and frame advancement in another way. What
- environment is this to run in?
