Tony,

I've recently run into this myself.
After a bit of experimentation, I've had consistent success with passing
it a filehandle opened for writing with :element-type :default, like so:

(with-open-file (outstream #p"/path/to/outfile.pdf"
                             :direction :output
                             :if-exists :rename
                             :element-type :default)
 (pdf:with-document
    <PDF stuff goes here...>
    (pdf:write-document outstream)))

I first tried passing it a filehandle opened with :element-type
'(unsigned-byte 8) but it them complained that it didn't have a stream of
type character. I've no idea why you have to explicitly tell it to use the
default element-type, but also don't have the time to dig around and
figure that out.


HTH,
