i have a sequence of postscript files and want to slide show them with
a 0.5 second pause between files. i tried animate, which is too slow;
i also tried gs, which is very fast, but no pause can be set between
two files. are there any other programs in linux to do this?

If you have 'convert', then you can do it
by
convert -delay 50 *.ps a.gif
then a.gif contains all ps files with 0.5second
time interval. You need to play a.gif by
xanim or netscape. It seems xv does not
work.

the resulted gif file is too huge, my 12 ps files, 40Kb each, were converted
to a 13Mb gif file, and it took rather long to load this gif into memory to
animate it.

use lower resolution to convert ps to gif. Or you can use xv to convert
ps to gif (which will lead to a file with rather small size).

That is right. Use other techniques (such as xv) to convert
your ps files into gif files one by one. And then
convert -delay 50 *gif a.gif
to make the animation.

right! and i now use xv directly to slide show these ps files
xv -crop 20 40 600 600 -wa 0.5 -wl box468p1.sgm??.ccd1.ps
