[OS X TeX] graphic conversion

[Denis Chabot]

Wow, I got many very useful answers to my question about spaces in file 
names, thank you.

With hope of as much success here is another question. I posted it on 
the R for Mac list (r-sig-mac at stat.math.ethz.ch) and people have tried 
to help me but we did not find the ultimate solution yet.

More and more I do my scientific plots with R. The output looks very 
good and the plots are pdf files cropped to show just the plot (instead 
of a small plot on a full page like you get in other graphics packages 
that produce pdf only through "print as pdf").

This is perfect when I produce a LaTeX document.

But I sometimes must show my results in a PowerPoint presentation 
(Keynote is not an option with the computer I have at the moment). You 
must know that Microsoft has not managed to make its apps able to 
import pdf graphics. Oh they let you insert such files. But some 
rasterization happens without you being told, and at a low resolution 
making the plots look very fuzzy, even at screen resolution. They look 
awful blown on a wall, let me tell you.

At least PowerPoint has always imported vector graphics in the pict 
format. Still does. I also make graphs with KaleidaGraph and vector 
pict files are easy to produce and import in PowerPoint. They look very 
crisp, as you'd expect. The look I'd like my pdf plots to have!

So I thought it should be easy to take a vector pdf graphic and turn it 
into a vector pict file. I was wrong. I tried Preview, Illustrator, 
Graphic Converter, Intaglio. They all say they can convert pdf to pict. 
But they all produce a raster pict.

Does anybody here know of a way to do this?

I'd also like to go from vector pict to vector pdf to include plots 
produced with KaleidaGraph into LaTeX documents...

Thanks

Denis
p.s. I've complained to Microsoft, so maybe they'll fix this within the 
next decade
