BandSelector2D seems to choose the target visible band incorrectly. A patch
that would possibly fix the problem is attached, some code to reproduce the
bhaviour is here below. Simply run this code on an RGB image.
// //
//
// Do the actual band selection.
//
// //
final DefaultProcessor processor = new
DefaultProcessor(
null);
// get the source
final ParameterValueGroup parameters =
processor
.getOperation("SelectSampleDimension")
.getParameters();
parameters.parameter("SampleDimensions").setValue(
new int[] { bandIndex -
1 });
parameters.parameter("Source").setValue(source);
// //
//
// Save the output
//
// //
GridCoverage2D output =
(GridCoverage2D) new SelectSampleDimension()
.doOperation(parameters, null);
