Class ChannelSelectionUpdateStyleVisitor

  • All Implemented Interfaces:

    public class ChannelSelectionUpdateStyleVisitor
    extends DuplicatingStyleVisitor
    ChannelSelectionUpdateStyleVisitor is a DuplicatingStyleVisitor that is used to "reset" style symbolizer's selection channel order when the GridCoverageReader used to read a coverage supports band selection. If a reader supports band selection then channel ordering is done by band selection from the reader, so symbolizer does not need to re-apply selection channel order.

    Also, see AbstractGridFormat.BANDS for the reader band selection parameter description.
