Detailed Documentation

Fields

Factor colorDstFactor

Source blending factor for the color channels.

Equation colorEquation

Destination blending factor for the color channels.

Factor alphaSrcFactor

Blending equation for the color channels.

Factor alphaDstFactor

Source blending factor for the alpha channel.

Equation alphaEquation

Destination blending factor for the alpha channel.

Methods

static constexpr BlendMode Alpha()

Blend source and dest according to dest alpha.

static constexpr BlendMode Add()

Add source to dest.

static constexpr BlendMode Multiply()

Multiply source and dest.

static constexpr BlendMode None()

Overwrite dest with source.

static void setMode(const BlendMode& mode, bool force = false)

Set a Predefined Blend Function

Parameters:

mode	The Blend Mode
force	If force to apply the blend ( no matters if the last blend was the same blend )

static BlendMode getPreBlendFunc()

Returns:

The last used predefined blend func

std::string toString() const

Blending equation for the alpha channel.
