Unsupported

data class Unsupported(val type: Int, val domain: DoubleArray, val range: DoubleArray?, val outputCount: Int) : PdfFunction

Placeholder for function types we don't fully evaluate (Type 0 sampled, Type 4 PostScript calculator). Returns an all-zero output of the right length so callers don't crash; shadings using these degrade to flat black (or to the background color, if any).
