- colour.models.exponent_function_monitor_curve(x: ArrayLike, exponent: ArrayLike = 1, offset: ArrayLike = 0, style: Literal['monCurveFwd', 'monCurveRev', 'monCurveMirrorFwd', 'monCurveMirrorRev'] | str = 'monCurveFwd') NDArrayFloat [source]#
Define the Monitor Curve exponent transfer function.
- Parameters:
x (ArrayLike) – Data to undergo the monitor curve exponential conversion.
exponent (ArrayLike) – Exponent value used for the conversion.
offset (ArrayLike) – Offset value used for the conversion.
style (Literal['monCurveFwd', 'monCurveRev', 'monCurveMirrorFwd', 'monCurveMirrorRev'] | str) –
Defines the behaviour for the transfer function to operate:
monCurveFwd: Monitor Curve Forward exponential behaviour where the definition applies a power law function with a linear segment near the origin.
monCurveRev: Monitor Curve Reverse exponential behaviour where the definition applies a power law function with a linear segment near the origin.
monCurveMirrorFwd: Monitor Curve Mirror Forward exponential behaviour where the definition applies a power law function with a linear segment near the origin and mirrors the function for values less than zero (i.e., rotationally symmetric around the origin).
monCurveMirrorRev: Monitor Curve Mirror Reverse exponential behaviour where the definition applies a power law function with a linear segment near the origin and mirrors the function for values less than zero (i.e., rotationally symmetric around the origin).
- Returns:
Exponentially converted data.
- Return type:
