I'm having trouble with filesizes of the .eps export... file sizes are very big, and I'm guessing it's because of some sort of preview bitmap that's being written into the .eps file. If I downscale all the stuff I have drawn in inkscape, and then save, the file size of the eps drops very fast. But there is no option to "don't save preview"! I have tried changing all the dpi values from every place I could find them, but this doesn't help.

I don't know the answer to this, but think I remember seeing another message about this. Maybe try searching forums while waiting for someone who knows the answer to reply?
