Extracts the band and palette properties of a raster feature and exposes them as attributes.
The following band and palette properties are exposed:
_band{}.band_name
_band{}.band_interpretation
_band{}.band_bit_depth
_band{}.band_interleaving
_band{}.band_num_tile_rows
_band{}.band_num_tile_columns
_band{}.band_nodata
_band{}.band_num_palettes
_band{}.palette{}.palette_name
_band{}.palette{}.palette_key_interpretation
_band{}.palette{}.palette_value_interpretation
_band{}.palette{}.palette_bit_depth
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.
Input Ports
Input
Input features must contain raster geometries only.
Parameters
None.
Usage Notes
- This transformer extracts only band and palette properties. To extract raster geometry properties, such as the number of rows and columns, use the RasterPropertyExtractor.
- This transformer is unaffected by raster band and palette selection.
Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click 
beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
