Removes all unselected bands from a raster feature.

Jump to Configuration

Typical Uses

  • Removing raster bands to meet processing or format requirements.

How does it work?

The RasterBandKeeper receives raster features and removes any unselected bands.

If all bands are selected, the raster will remain unchanged.

On reading, raster features by default have all bands currently selected. The selection may be changed by using the RasterSelector.


Usage Notes

  • The RasterBandKeeper and RasterBandRemover perform similar functions. The RasterBandKeeper is more useful when removing a proportionately large number of bands, whereas the RasterBandRemover is more useful when removing a small number of bands.

Choosing a Raster Transformer

FME has an extensive selection of transformers for working with raster data. They can be generally categorized as working with whole rasters, bands, cells or palettes, and those designed for workflow control or combining raster with vector data.

For information on raster geometry and properties, see Rasters (IFMERaster).
