Related Transformers


Identifies the palette key that matches a raster band’s Nodata value, and sets a value on it.

Jump to Configuration

Typical Uses

  • Adding or altering the representation of Nodata values on a palette.

How does it work?

The RasterPaletteNodataSetter receives raster features and sets a specified value on the palette key that matches the selected band’s Nodata value. That is, if the Nodata value is zero (0), it will find the palette entry with a key of zero (0) and change that entry’s value.

The raster band must have a Nodata value already set, and have a palette.

RGB, RGBA, and string palettes are supported.

This transformer supports raster band and palette selection. The RasterSelector can be used to modify selection.


Usage Notes

  • This transformer does not alter the Nodata value on the band. To set the Nodata value on the bands of a raster, use the RasterBandNodataSetter.

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).
