}

The operation that takes source (output from the fragment shader), destination (value currently in the framebuffer attachment) and blend_constant input values, and produces new inputs to be fed to BlendOp.

Some operations take source1 as an input, representing the second source value. The dual_src_blend feature must be enabled on the device when these are used.

Variants

Zero

Always 0.

One

Always 1.

SrcColor

source component-wise.

OneMinusSrcColor

1 - source component-wise.

DstColor

destination component-wise.

OneMinusDstColor

1 - destination component-wise.

SrcAlpha

source.a for all components.

OneMinusSrcAlpha

1 - source.a for all components.

DstAlpha

destination.a for all components.

OneMinusDstAlpha

1 - destination.a for all components.

ConstantColor

blend_constants component-wise.

OneMinusConstantColor

1 - blend_constants component-wise.

ConstantAlpha

blend_constants.a for all components.

OneMinusConstantAlpha

1 - blend_constants.a for all components.

SrcAlphaSaturate

For the alpha component, always 1. For the color components, min(source.a, 1 - destination.a) for all components.

Src1Color

source1 component-wise.

OneMinusSrc1Color

1 - source1 component-wise.

Src1Alpha

source1.a for all components.

OneMinusSrc1Alpha

1 - source1.a for all components.
