Java2DRenderer.getPageImage(): Extract code into a protected method.
Java2DRenderer.getPageImage(): Extract code into a protected method to
instantiate the BufferedImage that we paint on. Right now, it always
allocates an 24 bit RGB image with an 8-bit alpha channel.
In next patch: Override the new protected method described above to create the
Buffered image depending on the configuration.

I also have tryed to put jai_core.jar, jai_imageio.jar and jai_codec.jar on the
classpath of the aplication (not in the jdk) and the patch went fine.
Today I finish my job in notariado.org so I wont be available on
ohernandez@notariado.org. For further contact please e-mail me in
tramuntanal@gmail.com.
Special thanks to Jeremias, don't hesitate to contact me for any topic.

Patch applied with modifications. Thanks Oliver!

You'll see from the change that I've solved the multi-page problem with the
ImageWriter. Please test and send feedback if it works for you, too. I'll write
some docs about it in the meantime.

Sorry, but I had a lot of problems with a proxy and couldn't do an update. I did
a visual comparation to the source from web and it seemed to me that I had the
same source, but it was old. sorry, today I've solved the problem but i see you
did the update manually. Thanks!

Today I've been trying the patch with CCITT T.4, CCITT T.6 and PackBits. All
has worked fine. I ran everything in a Windows XP PC with jdk 1.5.0_03 and jai
tools installed on the jdk.
There's a little quality difference between CCITT T.4 and PackBits that I
think it's due to the inherent compression of each type, or maybe some
antialiasing on PackBits. Anyway the difference of quality is widely compensed
by the difference of weight 2592kB on PackBits vs 240kB on CCITT T.4 for the
same rendered MTIFF.
Apparently there's no significant difference between CCITT T.4 and CCITT T.6.
