You are here: Rasters > RasterPaletteGenerator


Generates a palette out of the selected band(s) of a raster. The output raster will have the selected band(s) replaced by a new band with a palette.

For example, if Palette Key Interpretation Type is set to UInt8 and Maximum Number of Palette Entries to 87, the generated palette will only have Uint8 keys and a maximum of 87 unique entries.

This operation may be lossy if an explicit maximum number of entries is used that is less that the number of unique band entries. In this case, the data values in the palette may not capture all the original band data values.

Usage Notes

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