I found what was missing, aside form jai_core and jai_coded there also
is a jai_imageio (1.2). I didn't find it mentioned anywhere, but a
google on jai and imageio led me to it. Including that in the classpath
(and jai_core) adds TIFF readers and writers to ImageIO. There also are
native libraries included, but I was able to read and write tiff without
them. Some documentation on why these are present would have been nice.

Tom,
FYI, I have been having a similar problem with getRGBImage() returning null, but I have not been able to get any help on it.
I have submitted my problem on Apache JIRA as a bug at
https://issues.apache.org/jira/browse/PDFBOX-616. You might want to look at
this bug report and see if your problem is the same as the one I reported.

Subject: TIFF
I've been trying to get this PDF thingy to work in a number of different ways
now, but a combination of PDFBox and iText seems to get me closest. PDFBox will
do the parsing, iText the writing. The only problem I currently have left ATM,
is that I need to extract TIFF images from PDF's and save them uncompressed to
files, even if the TIFFs inside the PDF are compressed.
Now, I've got the compressed tiff, I can save it to file using write2file, but I cannot
get my hands on an uncompressed version of the image; the getRGBimage returns null. The
source code says: "Returns an image of the CCITT Fax, or null if TIFFs are not
supported. (Requires additional JAI Image filters )"
I've got jai_core-1.3.0 and jar_codec_1.3.0 included... What is missing?
