Critical virtual bands bug
2/17/10 7:56 PM
In the current 4.7 the GPF has lost the ability to process virtual bands.

If an operator creates a new virtual band in the target product
createImages in OperatorExecute throws with "The band '%s' of the '%s' does not have an associated target image."

This used to work before and it is very critical that it continue to work as quite a few operators create virtual bands.

This can be fixed with the following change in OperatorExecute

 1
 2   private static PlanarImage[] createImages(Band[] targetBands, OperatorContext operatorContext) {
 3        final ArrayList<PlanarImage> images = new ArrayList<PlanarImage>(targetBands.length);
 4        for (final Band band : targetBands) {
 5            OperatorImage operatorImage = operatorContext.getTargetImage(band);
 6            if (operatorImage != null) {
 7                images.add(operatorImage);
 8            }
 9        }
10        return images.toArray(new PlanarImage[images.size()]);
11    }


Thanks
