mailing list.
Julien - I need to render images (PNG, JPEG, GIF) on a server, for transmission
to a client over the web. So I don't want to use Swing, AWT or any
desktop-based windowing frameworks. Ideally I'd just like to render a
BufferedImage.
Don/Jeff - thanks for the suggestions. Given that I can already create a 2D array of
values (a "raw" array, separate from the whole GeoGrid set of classes), I think
it's worth my looking at VisAD and seeing if I can use this directly, outside of the IDV.
Does this sound like a good idea?
Jon -
I have done exactly this - utilize the VisAD library outside of IDV to
create BufferedImage objects
for web distribution. My scenario is this - I have an applet on a web
page that sends a data request
to a servlet on the web server which uses VisAD to acquire and format
the data. Once handed back
to the applet, the data is stuffed in a BufferedImage for display.
Email me direct if you'd like more
info. Here is an example, which gives users global real-time satellite
data in one click:
