If you can provide a small sample rendering (to the list if < 10K-20K, or
to me if larger) it might help. Sometimes people don't recognise anti-aliasing
for what it is.

access control exception from rhino, but not java?
Posted by Denis Bohm <de...@fireflydesign.com>.
I'm using the Batik JSVGCanvas in a JApplet. I also have a Java class that
creates a multicast socket, joins a group, and sends some data. When I run
it directly from JApplet it works fine. When I try to run it from an SVG
script I get the access control exception shown below. Any idea why this
would be happening?
java.security.AccessControlException: access denied

Yes I do see the fuzziness around the letters. Thanks to both of you for
helping on this.

Hi David,
Thanks for doing that it may help Chris understand what AA looks like,
however my comment was really directed at Chris (I was just following up to
your note because it was the last in the thread - sorry for the confusion).
So Chris do you see the little 'fuzzy bits' around your letters?

Thanks for your help with this. I went back to my original data and my
images are anti-aliased. I guess I was expecting a bit more "blur". The
Adobe SVG viewer seems to do more filtering in its "High Quality" mode but
the Batik output is much better.
Chris

Ok... I've attached the text01 example from the SVG spec, an antialiased
png file resulting from batik-rasterizer, and a crop with the pixels
blown up to 400% and with an opaque background so you can see the
antialiasing more clearly.
