TIFFRenderer
Hello!
I'm just wondering if fop developers are interested in one more output format
such as TIFF ?
I beleive it's very easy to produce tiff having AWTrenderer. The only things
one have to do is to extend AWTRenderer, to pick up generated BufferedImages
page by page and to encode them by tiff encoder.
Actually I developed such TIFFRenderer a couple weeks ago in order to get
fax-suitable output from a fop-running system I'm working on now (see
http://www.tkachenko.com/fop/tiffrenderer.html). That stuff was downloaded
couple of dozens times by the people, so I believe some kind of interest among
fop users does exist. btw, size of Batik-dependent version of TIFFRenderer is
only 56 kB.
Well, I do like fop and I'd be glad to contribute that humble piece of code to
the project.

You mean GhostScript + ImageMagick probably, I have tried that conversion
using JMagick (java clone of ImageMagick) and it worked for me, but I was not
satisfied with a performance, producing pdf and converting it to tiff using 2
native libraries looks worse to me than producing tiff at once. But having
quality as high priority that way is probably more suitable.

No; but my understanding is that it is now committed to cvs - at least
in the maint branch, in what will be the upcoming 0.20.4 maint release.
The change is confined one method (renderWordArea) in
...fop.render.awt.AWTRenderer.

In the next: 0.20.4. It's already fixed in CVS. Christian has announced
that we can expect a candidate release around June 1st.

Are the AWTRenderer spacing fixes in a release version of FOP? If so, which
version?

Actually, I (biased!) think the present awt renderer is quite good; the
character spacings problems within words that existed in previous versions
is fixed, and text decorations seem to work correctly.
As Jeremias pointed out, I am chasing a new problem - but that one doesn't
really bear on awt itself, but shows up only when the awt renderer is used
to print. (The problem appears if fop is run w/ -print option or if the
print
command is invoked on the -awt display dialog.)
Offhand, I do not expect the printing problem to show up if the awt
renderer were used as the basis for a tiff renderer.
We believe the printing problem stems from a java bug around fonts -
the character rasterizer seems to be ending up with text strings being
improperly sized when it is drawing into a graphics context created by
a PrinterJob. There are several related bugs in the bug parade on this
matter.

Ralph LaChance is working on it. Check the current CVS. Ralph's diff
should have improved some of this. But it seems like AWT still has its
pitfalls.
Implementing a full bitmap renderer without the use of AWT would be a
major pile of work, I think. But you can always try to use GhostScript
to convert a PDF/PS to TIFF which should have about the same qualities
as the PDF. Which method are you using right now?

Yes, that's known AWTRenderer's problem, but proposed TIFFRenderer being
derived from AWTRenderer at least doesn't add any new problems, so we still
have only one :)

We would be real interested in TIFF rendering from FOP since our application
includes a fax component. My only concern is the use of the AWTRenderer.
Whenever we use the AWTRenderer the output (on screen and print) is not as
crisp and sharp as the PDF version. The spacing of letters and words is a
major issue with the AWTRenderer (as was mentioned in a previous thread).
If however a TIFF renderer could be produced that does NOT have these issues
we would be real happy to use it.

I think you're the second one who announced such a TIFF renderer in a
short period of time. Personally, I would like to see a bitmap renderer
in FOP even though I don't have an immediate need myself. I'd like to offer
my sponsorship. If no other committer wants to take it, I'm going to look
at the two submissions as soon as possible and see how best to integrate
one (or a combination of both) into FOP. If someone is against that move,
please speak up.
