Nope.  Your code looks fine to me (not sure why you want ABGR instead of  
ARGB, but either works fine on my computer).

Using basically the same code here, it generates an anti-aliased circular  
subset of the original image, just as intended.

Java 5, Mac OS 10.4.11

My best guess: you are either using some Java implementation that has poor  
or non-existent anti-aliasing support, or you're just mistaken about  
whether the results are anti-aliased or not.  I admit, by default I'd  
assume that neither is the case, but given that the code is simple and it  
works fine here, I've got to assume one or the other is actually the case  
after all.  :)

If you're not using an up-to-date, mainstream Java implementation, then  
you should try the same code on one that is.  If you already are (or if  
doing so produces the same results), then maybe you can post an example  
image that's been processed by your code somewhere that we can download  
and look at it.
