Sun provides the JAI addon with support for additional graphical formats including multi-page tiff for faxes and ppm files used with xpdf for pdf support on unix systems. For Linux and Windows go to and download and install JAI for your platform. For the Mac go to Note: there seem to be two JAI's to install - the connection between them is not clear to me. Make sure to install the "JAI Image I/O API" along with the JAI itself.
