maybe, but I wouldn't be so sure. currently the pdf is created in a python StringIO buffer and returned to the browser; so it never becomes a file. using convert means I have to first save it as a file, convert from file to file, read the file, delete the 2 files. so 6 file operations where before there were none. That may be more of a load than the ghostscript part. Carl K -- http://mail.python.org/mailman/listinfo/python-list
