Re: [Opengrads-devel] Setting graphic window size GrADS nder JVM

hi Arlindo,
I fixed the issue with setting the initial GrADS window size via the command line.
Attached are 3 files that have been modified and added (JGrads.java, gxJ.java, and ConfigInfo.java). For development purpose and to try it out, you can copy these files to your working directory where all the code are, and then
javac JGrads.java gxJ.java

All,
Weekend update: I did some work on the Java graphics and added a
readline replacement. The graphics look quite descent, even nicer
than X on my Mac. I am using the same trick I used for gxyat: lines
are drawn with anti-aliasing, while polygon fills are not (or else you
get those funny horizontal lines).
I'd appreciate any feedback regarding performance compared to the C
version with *your* data on *your* platform. Of course, this is Java,
it is supposed to be slower. The queston is: is it usable?
Thanks,
Arlindo
