Detailed Description

Represents power functions with a linear section in the shadows such as sRGB and L*.

The basic formula is::

pow( (x + offset)/(1 + offset), gamma ) with the breakpoint at offset/(gamma - 1).

Negative values are never clamped.

Specifies how negative values are handled. Legal values:

  • NEGATIVE_LINEAR – Linear segment continues into negatives (default).
  • NEGATIVE_MIRROR – Positive curve is rotated 180 degrees around the origin to handle negatives.

ExponentWithLinearTransform& OCIO_NAMESPACE::ExponentWithLinearTransform::operator= ( const ExponentWithLinearTransform )
virtual void OCIO_NAMESPACE::ExponentWithLinearTransform::setGamma ( const double(&)  values[4])
pure virtualnoexcept

Set the exponent value for the power function for R, G, B, A.

The gamma values must be in the range of [1, 10]. Set the transform direction to inverse to obtain the effect of values less than 1.
virtual void OCIO_NAMESPACE::ExponentWithLinearTransform::setNegativeStyle ( NegativeStyle  style)
pure virtual
virtual void OCIO_NAMESPACE::ExponentWithLinearTransform::setOffset ( const double(&)  values[4])
pure virtualnoexcept

Set the offset value for the power function for R, G, B, A.

The offset values must be in the range [0, 0.9].
