Usage

In practice

  • Use Posterize when the graph needs Quantizes RGB into discrete normalized color levels.
  • Quantizes clamped RGB while leaving alpha alone; Steps counts RGB levels including black and white.
  • Place it after the image or mask it should process, and check its alpha and edge behavior before using the result in a tiled graph.
  • Levels Remaps tonal range: input range, gamma, output range.
  • Colorize Maps an Image scalar field through a four-stop colour ramp; use Color Ramp only for a Scalar value.
  • Invert Blends RGB and alpha inversion independently.
