Examples of ae.sun.java2d.pipe.SpanIterator.nextSpan()

ae.sun.java2d.pipe.SpanIterator.nextSpan()
This method returns the next span in the shape being iterated. The array must be of length at least 4 and upon return, it will be filled with the values:
```
 {SpanMinX, SpanMinY, SpanMaxX, SpanMaxY}. 
```

            }
            int span[] = {dstx, dsty, dstx+width, dsty+height};
            SpanIterator si = clip.getSpanIterator(span);
            srcx -= dstx;
            srcy -= dsty;
            while (si.nextSpan(span)) {
                int w = span[2] - span[0];
                int h = span[3] - span[1];
                srcRas = srcRas.createChild(srcx + span[0], srcy + span[1],
                                            w, h, 0, 0, null);
                dstRas = dstRas.createWritableChild(span[0], span[1],
