I've tried several ways to convert it to eps with a tight bounding box. I've tried, among many other things
inkscape in.pdf -D --export-eps=out.eps
epstool --bbox --copy in.eps out.eps
inkscape does a great job of putting a tight bound on the box above, to the left and right of the figure, but fails to remove the whitespace at the bottom, i.e., it produces this
It's hard to see what's really happening because I can't seem to import the actual eps file, but you can see from the images that the except for the bottom, the pic is well cropped.
Could anybody please suggest how to crop the bottom tightly?
Thanks very much
