Hi Ryan
It's not "JAI", you need "JAI Image I/O Tools". The JAR filename is
"jai_imageio.jar". In recent FOP releases we don't have support for JAI
directly anymore. Instead we're relying completely on the ImageIO API
that is available in every Java Runtime since Java 1.4. "JAI Image I/O
Tools" provide additional codecs for the ImageIO API which includes a
TIFF codec with CCITT support.
I've just verified with FOP 0.95 and Trunk and in both cases I can
generate CCITT Group 4 TIFFs with the following configuration snippet
for the TIFF renderer:
<renderer mime="image/tiff">
<compression>CCITT T.6</compression>
</renderer>
