Original good EPS

Hiya

I have an EPS file which has:

%%BoundingBox (atend)
..
..
%%BoundingBox 0 0 259 255

When converting this to a PDF using:

  gs -dEPSCrop -sDEVICE=pdfwrite -sOutputFile=foo.pdf foo.eps

it ignores the BoundingBox and renders the EPS in the bottom left hand corner
of an otherwise blank page.

Kens on IRC recommended that I replace the (atend) with the values from the
last BoundingBox statement in the file.

This works correctly for 80% of the EPS files, but for some of them, I get this
error:

   GPL Ghostscript 8.71: ./psi/iscan.c(333): Can't refill scanner input
buffer!GPL Ghostscript 8.71: Unrecoverable error, exit code 255

If I run the file through ps2epsi or ps2eps then I get an EPS file that I can
convert to PDF correctly.

I attach an example of an EPS file that works when edited, and one that throws
the error.

thanks
