  1. def sigmoidal(alpha: Double, beta: Double): MultibandTile

    Given the parameters alpha and beta, perform the sigmoidal contrast computation on each band and return the result as a multiband tile.

    Given the parameters alpha and beta, perform the sigmoidal contrast computation on each band and return the result as a multiband tile.

    The approach used is described here: https://www.imagemagick.org/Usage/color_mods/#sigmoidal

    alpha

    The center around-which the stretch is performed (given as a fraction)

    beta

    The standard deviation in the computation, used to avoid saturating the upper and lower parts of the gamut

    returns

    The output tile
