Returns
| Type | Description |
|---|---|
| Single |
Init(Single, Single, Single, Single, Single, Single)
Initializes the curve.
Declaration
public void Init(float toeStrength, float toeLength, float shoulderStrength, float shoulderLength, float shoulderAngle, float gamma)Parameters
| Type | Name | Description |
|---|---|---|
| Single | toeStrength | The strength of the transition between the curve's toe and the curve's mid-section. A value of 0 results in no transition and a value of 1 results in a very hard transition. |
| Single | toeLength | The length of the curve's toe. Higher values result in longer toes and therefore contain more of the dynamic range. |
| Single | shoulderStrength | The strength of the transition between the curve's midsection and the curve's shoulder. A value of 0 results in no transition and a value of 1 results in a very hard transition. |
| Single | shoulderLength | The amount of f-stops to add to the dynamic range of the curve. This is how much of the highlights that the curve takes into account. |
| Single | shoulderAngle | How much overshoot to add to the curve's shoulder. |
| Single | gamma | A gamma correction to the entire curve. |
