Alters the underlying interpretation of the bands of the raster geometry on the input features, using the specified conversion options.
For example, an input raster feature with three bands of interpretation (UInt16, Gray8, and Real64) could be converted to a raster feature with three bands of interpretation (Red8, Green8, and Blue8) or four bands of interpretation (Red16, Green16, Blue16, and Alpha16) in a single operation.
This parameter selects the destination interpretation along with the bit depth. Different interpretations allow for different conversion options to be used. If any bands on the raster contain palettes, then the destination interpretation is restricted to UInt8, UInt16 or UInt32.
When converting to an interpretation with multiple components, such as RGB and RGBA, the raster will be expected to have exactly 1, 3, or 4 bands. If only one band is supplied, it will be cloned and converted to the appropriate interpretation. When converting to a single color or numeric interpretation, multiple input bands will be averaged into a single one.
The RGBA to RGB parameter selects the action to perform when converting four bands representing an RGBA raster to three bands representing an RGB raster.
This parameter selects the action to perform when converting three bands representing an RGB raster to four bands representing an RGBA raster.
These parameters select the action to undertake when the given conversion between different types occurs.
This parameter specifies the action to perform when converting from a floating-point value to an integer.
Each RasterInterpretationCoercer performs a conversion on the input raster. If multiple RasterInterpretationCoercers are used in sequence, then multiple conversions will take place; data quality and translation performance may suffer.
This transformer is unaffected by raster band and palette selection.
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.
