I had to get the pst-xkey packagee to get things to compile but that just
took a few more minutes before I could try it.

Indeed, the method used to determine the BoundingBox in ps4pdf is failing in
this situation. I haven't had a chance to look in detail but it looks as
though the input produced by ps4pdf to the latex command has each graphic
set in a box and that is sent through the preview package which puts each
graphic on a page by itself in a single file. It appears that the box's size
is calculated incorrectly in this case.

The individual files produced by pdftricks are full page with one graphic
and one page in each file; the BoundingBox is actually set by the pdfcrop
command after the .pdf is generated. (Hmmm... What happens if you put too
large a graphic on a page?)

So far pdfcrop, as used by the modified pdftricks seems to do the best job
of determining the BoundingBox.

Good Luck,
