  setBlendMode(mode: NPDFBlendMode): void
  setOverprint(v: boolean): void
  setFillOverprint(v: boolean): void
  setStrokeOpacity(v: number): void
  setStrokeOverprint(v: boolean): void
  setNonZeroOverprint(v: boolean): void
  setRenderingIntent(intent: NPDFRenderingIntent): void
  setFrequency(v: number): void
}

Constructors
