fmeobjects.FMERasterTools.convertPaletteInterpretation

FMERasterTools.convertPaletteInterpretation(keyInterpretation, valueInterpretation, palette, nodataKey, parms)

Converts data type of a palette.

Note that this method is similar to convertInterpretation with a mode of FME_REINTERPRET_MODE_PALETTE, except that this operates directly on a single palette, rather than on all the selected bands of a raster.

Parameters:

• keyInterpretation (int) –

  Specifies the desired interpretation of the palette after processing. Choose one of:

  FME_INTERPRETATION_UINT8 FME_INTERPRETATION_UINT16 FME_INTERPRETATION_UINT32

• valueInterpretation (int) –

  Specifies the desired interpretation of the palette after processing. Choose one of:

  FME_INTERPRETATION_NULL FME_INTERPRETATION_RGB24 FME_INTERPRETATION_RGBA32 FME_INTERPRETATION_RGB48 FME_INTERPRETATION_RGBA64 FME_INTERPRETATION_STRING

• palette (FMEPalette) – The palette to apply conversion to.

• nodataKey (FMETile) – (Optional) Specifies the nodata value of the palette. It must have the same interpretation as the existing palette.

• parms (dict[str, str]) – (Optional) Name-value pair that contains information on how to do specific conversions. Same parameters as in convertInterpretation().

Return type:

FMEPalette

Returns:

The palette after converting the interpretation.

Raises:

FMEException – An exception is raised if an error occurred.
