[xmlvm-users] Releasing of CGBitmapContextRef / CGImageRef

[JR S. <sc...@we...>]

I am curious how CGBitmapContextRefs generated by 
CGBitmapContext.create() are handled, if at all.  A similar issue arises 
with CGImageRef created.

I looked at the C implementation, and from my high-level understanding 
of the code it doesn't appear that there are any finalizers to take care 
of this.  (The DELETE method is empty). Adding to my concern is that the 
objc impemtetion does contain a "release" method that properly calls 
CGContextRelease.

So I am wondering:
1)  Is "CG" resource management being done in the c implementation? If 
so, how?
2)  If no resource management is being done, is there a way to release 
them manually?  I fear that this will require modifying the c 
implementation, which looks extremely difficult.
3)  Alternatively, is it possible to mix-and-match the objective c and c 
implementations of the XMLVM classes?  Writing the objective c 
implementations looks far more straightforward, but I still the c back 
end for full java classlib compatibility.

Thanks in advance for any advice!
