So I am also sending this to both the pstricks and the powerdot lists as it relates to both, but mostly to compiling via dvi-> dvips -< ps2pdf or similar.
I make my lecture slides with Powerdot and use pstricks a lot to create arrows, circles, diagrams and so on. But I also include eps figures, some on which I operate with pstricks.
The problem is that some of my eps files (such as from Mathematica or ones I have converted my jpg with lots of resolution are very large ( 50--60 mb)
This then makes the latex compiling take forever.
I sometimes use an include statement so I can % out the worst of these slides except on final compilation, but this get annoying,
Anyway to precompile some of this stuff so that the final compile takes less time,
pstricks
let produce an.eps
file, which is then later on included into another document, as here: tex.stackexchange.com/questions/172764/opacity-and-transparency/…eps
files generated by Mathematica without reducing the image quality. This answer may be of interest.
