[powerdot] Re: how to handle large eps files in powerdot?

Hello to all,
I've been reading with interest your comments and I'm replying to the last email on this issue but keeping in mind all other comments as well. The eps that I'm generating is either using Laprint in Matlab and using gnuplot. In Matlab I get the resulting eps file around 6 MB, while with gnuplot and metapost I get the resulting eps file around 14 MB. The reason for such a large file is that there are many points in the plot. If I choose to downsample the number of points then sharp edges in the plot won't no longer appear as sharp edges. By the way, I'm working with bifurcation diagrams in nonlinear dynamics.
Producing a small eps file is not possible in the first place. I have Adobe Illustrator and gsview/ghostscript and I would like to know if these programs can be used to rasterize the eps. A quicker fix would be of course to save a snapshot of the figure in the eps format. And trying to reduce the final presentation pdf file is a good thing to try as well.

    sometimes eps files get large because
    they are just pixmaps saved as eps,
    rather than being true vector files.
    but if you have myriads of entities,
    of course the eps can be huge legitimately.)

- if the latter is the case, rasterize
    your eps, reduce the image quality, and
    re-save as eps (which will then be a 'fake',
    rasterized eps. this is a somewhat more
    controlled alternative than screenshot.

Hello,
       I've been using powerdot for about two years and I'm very happy with
it. Lately, I've had some very large eps figure files from some simulations
and it has been clumsy to use powerdot as the resulting presentation file is
too big to be shared. I'm still using powerdot 1.3 with TexLive 2008.

What suggestions do you have for someone who has to include large eps
figure files with powerdot?

Thanks a lot...
