You are here: Rasters > RasterPaletteInterpretationCoercer


Alters the underlying interpretation of the palettes of the raster geometry on the input features, using the specified conversion options.

For example, an input raster feature with a single band with a single palette of interpretation RGB24 could be converted to a single band with a single palette of RGB64 or String data.


Usage Notes

Each RasterPaletteInterpretationCoercer performs a conversion on the input raster. If multiple RasterPaletteInterpretationCoercers are used in sequence, then multiple conversions will take place; data quality and translation performance may suffer.

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

Related Transformers

The RasterInterpretationCoercer performs similar operations on the raster as a whole, such as converting 4 bands directly to RGBA.

The RasterBandInterpretationCoercer performs similar conversions on individual bands.

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.
