Detailed Description

RGB curve color correction controls.

This transform allows for modifying tone reproduction via B-spline curves.

There is an R, G, and B curve along with a Master curve (that applies to R, G, and B). Each curve is specified via the x and y coordinates of its control points. A monotonic spline is fit to the control points. The x coordinates must be non-decreasing. When the grading style is linear, the units for the control points are photographic stops relative to 0.18.

The control points are dynamic, so they may be adjusted even after the Transform is included in a Processor.

Member Function Documentation

static GradingRGBCurveTransformRcPtr OCIO_NAMESPACE::GradingRGBCurveTransform::Create ( GradingStyle  style)

Creates an instance of GradingPrimaryTransform.

virtual bool OCIO_NAMESPACE::GradingRGBCurveTransform::equals ( const GradingRGBCurveTransform other) const
pure virtualnoexcept

Checks if this equals other.

virtual bool OCIO_NAMESPACE::GradingRGBCurveTransform::getBypassLinToLog ( ) const
pure virtual

The scene-linear grading style applies a lin-to-log transform to the pixel values before going through the curve. However, in some cases (e.g. drawing curves in a UI) it may be useful to bypass the lin-to-log. Default value is false.

virtual const FormatMetadata& OCIO_NAMESPACE::GradingRGBCurveTransform::getFormatMetadata ( ) const
pure virtualnoexcept
virtual FormatMetadata& OCIO_NAMESPACE::GradingRGBCurveTransform::getFormatMetadata ( )

virtual float OCIO_NAMESPACE::GradingRGBCurveTransform::getSlope ( RGBCurveType  c,
size_t  index 
) const
pure virtual

It is possible to provide a desired slope value for each control point. The number of slopes is always the same as the number of control points and so the control points must be set before setting the slopes. The slopes are primarily intended for use by config authors looking to match a specific shape with as few control points as possible, they are not intended to be exposed to a user interface for direct manipulation. When a curve is being generated for creative purposes it is better to let OCIO calculate the slopes automatically.

virtual GradingStyle OCIO_NAMESPACE::GradingRGBCurveTransform::getStyle ( ) const
pure virtualnoexcept

Adjusts the behavior of the transform for log, linear, or video color space encodings.

TransformType OCIO_NAMESPACE::GradingRGBCurveTransform::getTransformType ( ) const

Implements OCIO_NAMESPACE::Transform.

virtual const ConstGradingRGBCurveRcPtr OCIO_NAMESPACE::GradingRGBCurveTransform::getValue ( ) const
pure virtual
virtual bool OCIO_NAMESPACE::GradingRGBCurveTransform::isDynamic ( ) const
pure virtualnoexcept

Parameters can be made dynamic so the values can be changed through the CPU or GPU processor, but if there are several GradingRGBCurveTransform only one can have dynamic parameters.

virtual void OCIO_NAMESPACE::GradingRGBCurveTransform::makeDynamic ( )
pure virtualnoexcept
virtual void OCIO_NAMESPACE::GradingRGBCurveTransform::makeNonDynamic ( )
pure virtualnoexcept
GradingRGBCurveTransform& OCIO_NAMESPACE::GradingRGBCurveTransform::operator= ( const GradingRGBCurveTransform )
virtual void OCIO_NAMESPACE::GradingRGBCurveTransform::setBypassLinToLog ( bool  bypass)
pure virtual
virtual void OCIO_NAMESPACE::GradingRGBCurveTransform::setSlope ( RGBCurveType  c,
size_t  index,
float  slope 
pure virtual
virtual void OCIO_NAMESPACE::GradingRGBCurveTransform::setStyle ( GradingStyle  style)
pure virtualnoexcept

Will reset value to style's defaults if style is not the current style.

virtual void OCIO_NAMESPACE::GradingRGBCurveTransform::setValue ( const ConstGradingRGBCurveRcPtr values)
pure virtual

Throws if value is not valid.

virtual bool OCIO_NAMESPACE::GradingRGBCurveTransform::slopesAreDefault ( RGBCurveType  c) const
