FME raster features represent raster data and use several concepts that are unlike those used in the handling of vector data. See About FME Rasters.
SUNRASTER supports rasters with the following structures:
- a Gray8 band
- a Red8 band, a Green8 band, a Blue8 band, and optionally one more band with a UInt8 data type
- a UInt8 band with an RGB24 palette
