Band Filter

The BandFilter operator selects bands from a raster source by band names or band indices.

It removes all non-selected bands while preserving the original order of remaining bands.

Errors

The operator returns an error if no bands are selected or if selected band names/indices cannot be mapped to existing input bands.
