enum `SF::BlendMode::Equation` #

Enumeration of the blending equations

The equations are mapped directly to their OpenGL equivalents, specified by gl_blend_equation() or gl_blend_equation_separate().

Members#

`Add = 0`#

Pixel = Src * SrcFactor + Dst * DstFactor

`Subtract = 1`#

Pixel = Src * SrcFactor - Dst * DstFactor

`ReverseSubtract = 2`#

Pixel = Dst * DstFactor - Src * SrcFactor

`Min = 3`#

Pixel = min(Dst, Src)

`Max = 4`#

Pixel = max(Dst, Src)
