Band and Palette Selection
Rasters that contain multiple bands and/or palettes need not be split to be operated on individually. FME allows for individual band and palette selection for operational purposes. For example, an RGB raster that has three bands can have only the red band selected such that subsequent processing occurs only on the red band, and does not affect the remaining green and blue bands. Bands and palettes are selected based on their numeric location in the raster. The numerical relationship is zero based such that the first band is at index 0, the second band at index 1 and so on.
