RasterBandPropertyExtractor

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

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.
