colors should be much more intensive for #B3371F?!
I am using Batik with Cocoon2.
Comparing the generated image with the #B3371F colored environment the image
is much too bright.. furthermore the very top and very left line is
background colored and I can't help it.. is that a problem of mine only?
Thx,
Jan.

Hello Jan,
it seems you are running into the same problems I had ;-) IMHO both are bugs in
Batik, try these patches:
org.apache.batik.gvt.renderer.StaticRenderer, line 422/423: change +0.5f into
-0.5f -> should get rid of the edges
org.apache.batik.transcoger.image.PNGImageTranscoder, line 63: uncomment the
setGamma command -> removes the color problem
Another workaround is to use JPEGs instead (I assume you generate PNGs) or to
not use browsers that support gamma ;-)
One of the classfiles can be found here:
http://sourceforge.net/tracker/index.php?func=detail&aid=428271&group_id=25147&atid=383575
I can upload the other one, too.
HTH,
PeterB

I don't remember if you already get the answer. Anyway, the bright is due to
the gamma factor of the PNGTranscoder (something that has been/will be fixed
I think) and the thin line if also a bug that has been fixed by thomas
yesterday or today I think.
