Side note: JDK 1.3 supports PNG. However, I suspect they haven't changed
the rest of thier imageloading code so it still takes up 4 times the
amount of memory than it should.
We created a set of standard URL content handlers that we use to load an
image. ie, we create a java.net.URL (or fetch it from
ClassLoader.getResource()) and then getContent() on that. This returns
us a full java.awt.image.BufferedImage that we create in native code. On
the native side, we've just taken a bunch of the standard libraries from
off the 'net and thrown some native wrappers around it. Very simple,
very trivial. Actually, so trivial, it took us about 3 days to write
_every_ from scratch and we now support about 12 different image types.
Needless to say, we're absolutely boggled over why Sun has not done this
in the past. Surely one engineer for 3 days of work (shit, they can use
our code if they want!) would satisfy about 2 years worth of bug reports
on JDC, but apparently image loading memory consumption is not a concern
to Sun. They've never had to write a real Java application, just toy
demos so obviously it isn't a problem....
