OELinearColorGradient

class OELinearColorGradient : public OEColorGradientBase

The OELinearColorGradient class interpolates between colors that are defined by using the OEColorStop class. See Figure Example of linear color gradient

Example of linear color gradient with (-1.0, OERed), (0.0, OEWhite) and (+1.0, OEBlue) color stops

Constructors

OELinearColorGradient() -> OELinearColorGradient

Default constructor that creates an “empty” color gradient.

Note

An “empty” color gradient always returns the OEBlack color, when calling the OEColorGradientBase.GetColorAt, the OEColorGradientBase.GetMinColor or the OEColorGradientBase.GetMaxColor methods.

OELinearColorGradient(oneStop: OEColorStop) -> OELinearColorGradient

Creates an OELinearColorGradient object with one color stop. An OELinearColorGradient object that has only one color stop will always return that color when calling the OEColorGradientBase.GetColorAt method.

OELinearColorGradient(bgnStop: OEColorStop, endStop: OEColorStop) -> OELinearColorGradient

Creates an OELinearColorGradient object with interpolation range between the two specified color stops.

OELinearColorGradient(rhs: OELinearColorGradient) -> OELinearColorGradient

Copy constructor.

TransformValue

TransformValue(value: float) -> float

Performs a \(f(x) = x\) linear transformation. This method is called by OEColorGradientBase.GetColorAt method to transform a value before performing color interpolation.
