The above edit does this.
Ah... Interesting. I wonder how or if the "-dPDFSETTINGS=/prepress" setting and the ones that you suggested are related. Before trying your method my images were looking good, with a final PDF size of 6.4Mb. After altering my epstopdf script as you suggested, the PDF file is 54Mb, and the images *seem* to be the same.... however it would take a bit of research to find out just how different they are.

Well, it is a little easier on the eyes (similar to illustrator), but some features are still a little bit lacking... On Debian Testing it gets updated fairly often, and with each release gets better and better. -- Dylan Beaudette Soils and Biogeochemistry Graduate Group University of California at Davis 530.754.7341 _______________________________________________ vox-tech mailing list [email protected] http://lists.lugod.org/mailman/listinfo/vox-tech
