Thresholds an input color pattern to create a black and white mask. The falloff will define a gradual transition from black to white. The output is always between 0 and 1. @parameters

inputRGB: The color pattern you would like to threshold.

channel: The input channel this node will operate on.

threshold: The value at which the transition from black to white will take place.

transitionWidth: This control allows you to create a sharp or progressive transitions. The transition width is centered on the threshold value.

transitionProfile: The interpolation from black to white can be computed with three different curves: Linear, Smooth or Gaussian.
