By the way.
It is possible to transform to TIFF and many other formats from PDF format
using ghostscript.
Though it's not strictly Java solution.

Now I have my first question, so here goes. What is the recommended
approach to generate a TIFF output: using the SVGRenderer then
transcoding to TIFF with batik; using the TIFFRenderer written by Oleg?
Hard question. TIFFRenderer has some flaws: it is not thread-safe, because
AWTRenderer isn't. Another its problem is that all generated page images
are
held in memory. Both issues I hope will be fixed in FOP 1.0dev. So may be
SVGRenderer is a prefered approach at the moment.
The TIFFRenderer works, however the outputted TIFF is white text on
black background (should be the other way around). Maybe there is
something I need to configure correctly.
Well, which TIFF viewer are you using? AFAIK, there is a great mess
amongst
TIFF viewers what is white and what is black in b/w FAX compressed images,
e.g. consider given black-and-white TIFF image, Adobe Photoshop and
Windows
Imaging will show it differently black on white or white on black.
TIFFRenderer uses JAI encoder, which seems to be agree with Adobe in this
question, so I always rely on Photoshop and Alternatiff plugin and never
got
inverted image.
Actually I've been thinking about introducing such a parameter to
TIFFRenderer
to allow control over that. Ok, granted, will try this week.
There also doesn't seem to any new versions of the TIFFRenderer. The
latest I can find is 0.9 from May last year. Is this there an updated,
unreleased version somewhere?
Well, I just don't see how can I make it better, it's quite simple
wrapper,
which heavily rely on JAI encoder and AWTRenderer. Now, when I'm FOP
committer
I'd better be focused on how to make FOP itself better, TIFFRenderer will
benefit from it also.
