In addition, there's a Pointer.read() method that reads into an existing int[] to avoid allocating a new one every time.

That would be the best way if you're going to be accessing the pixels from java (Pointer and ByteBuffer ops will be slower than array element accesses).

Its not the copy that is killing performance, its the garbage collector.
