Extracts the band and palette properties of a raster feature and adds them to a list attribute.

Jump to Configuration

Typical Uses

  • Extracting band and palette information from raster features

How does it work?

The RasterBandPropertyExtractor receives raster features, and extracts any existing band and palette properties. The results are added to a new list attribute (because a raster may have multiple bands), and output with the original feature.

The transformer has no parameters.

Property attributes include:













Wherever "{}" appears, there will be one instance of the attribute for each band or palette. The first will appear with {0}, the second with {1}, and so on.

If a raster band has no palettes, _band{}.band_num_palettes will be zero (0), and no further palette attributes will be added.

This transformer is unaffected by raster band and palette selection.


Usage Notes

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).

This transformer has no parameters.

Editing Transformer Parameters

Transformer parameters can be set by directly entering values, using expressions, or referencing other elements in the workspace such as attribute values or user parameters. Various editors and context menus are available to assist. To see what is available, click beside the applicable parameter.
