Remarks

The RedBandIndex, BlueBandIndex, and GreenBandIndex properties of this interface control which band is displayed in each display channel.

The the band index is zero based, with a value of zero representing band one, a value of one representing band two, and so on. Each channel can be set to display or not display using the UseRedBand,UseGreenBand, and UseBlueBand properties.

To check or set the band indices for all three bands with one call, use the QueryBandIndices or SetBandIndices functions.
