[tex-k] dvips produces postscript which bombs out

Thanks much for looking at this Tom, and for the explanation. I'll file
a bug report with ImageMagick.

You're right, turning the compression off in IM (option +compress)
makes the whole process work. The non-compressed .eps file is over 10
times as big, but that's not a primary concern.

Yes, gs writes the current page size (A4, etc) into the pdf. I don't
know the specs for pdf and whether this is a bug in gs. Copying the 4
bbox numbers from the eps into the pdf makes things work (this could
even be scripted). Haven't tried gs 8.

IM 5.5.4 and 5.5.7 produce a .pdf which, after going through pdflatex,
does not show up as transparent.

How do you preview an eps or pdf and determine whether it has any
transparent areas? I haven't found a way yet to do this with gs or gv.
