BTW, if you happen to, for some reason, convert pdf to raster frequently, see ImageMagick's convert, which for some output formats (at least png and jpeg) does a batch export of all pages (as separate files). It will probably be handy when the PDF has many pages. -- Nuno J. Silva gopher://sdf-eu.org/1/users/njsg
