Expand description

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§
