    Subtraction,
    ReverseSubtraction,
}

Equation that the GPU will use for blending.

Variants

Min

For each individual component (red, green, blue, and alpha), the minimum value is chosen between the source and the destination.

For example writing (0.5, 0.9, 0.4, 0.2) over (0.9, 0.1, 0.4, 0.3) will result in (0.5, 0.1, 0.4, 0.2).

Max

For each individual component (red, green, blue, and alpha), the maximum value is chosen between the source and the destination.

For example writing (0.5, 0.9, 0.4, 0.2) over (0.9, 0.1, 0.4, 0.3) will result in (0.9, 0.9, 0.4, 0.3).

Addition

For each individual component (red, green, blue, and alpha), a weighted addition between the source and the destination.

The result is equal to source_component * source_factor + dest_component * dest_factor, where source_factor and dest_factor are the values of source and destination of this enum.

Subtraction

For each individual component (red, green, blue, and alpha), a weighted substraction of the source by the destination.

The result is equal to source_component * source_factor - dest_component * dest_factor, where source_factor and dest_factor are the values of source and destination of this enum.

ReverseSubtraction

For each individual component (red, green, blue, and alpha), a weighted substraction of the destination by the source.

The result is equal to -source_component * source_factor + dest_component * dest_factor, where source_factor and dest_factor are the values of source and destination of this enum.
