Struct palette::blend::Equations

pub struct Equations {
    pub color_equation: Equation,
    pub alpha_equation: Equation,
    pub color_parameters: Parameters,
    pub alpha_parameters: Parameters,
}

A pair of blending equations and corresponding parameters.

The Equations type is similar to how blending works in OpenGL, where a blend function has can be written as e(sp * S, dp * D). e is the equation (like s + d), sp and dp are the source and destination parameters, and S and D are the source and destination colors.

Fields

color_equation: Equation

The equation for the color components.

alpha_equation: Equation

The equation for the alpha component.

color_parameters: Parameters

The parameters for the color components.

alpha_parameters: Parameters

The parameters for the alpha component.

Implementations

impl Equations

pub fn from_equations(color: Equation, alpha: Equation) -> Equations

Create a pair of blending equations, where all the parameters are One.

pub fn from_parameters(source: Parameter, destination: Parameter) -> Equations

Create a pair of additive blending equations with the provided parameters.

Trait Implementations

impl<C, S, const N: usize, const M: usize> BlendFunction<C> for Equations

where C: Clone + Premultiply<Scalar = S> + Mul<Output = C> + Mul<S, Output = C> + ArrayCast<Array = [S; N]>, PreAlpha<C>: ArrayCast<Array = [S; M]>, S: Real + One + Zero + MinMax + Sqrt + IsValidDivisor + Arithmetics + Clone,

fn apply_to(self, source: PreAlpha<C>, destination: PreAlpha<C>) -> PreAlpha<C>

Apply this blend function to a pair of colors.

impl Clone for Equations

fn clone(&self) -> Equations

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Equations

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Equations

fn eq(&self, other: &Equations) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
