Implementations

impl BlendMode

pub const ALL: &[Self]

Every mode, in shader index order.

pub fn as_str(self) -> &'static str

The ffcine.comp.blend/1 name.

impl BlendMode

pub fn index(self) -> i32

The mode uniform of glsl.

pub fn apply(self, b: [f32; 3], s: [f32; 3]) -> [f32; 3]

B(b, s): backdrop b, layer s, both clamped to 0..1.

pub fn composite(self, b: [f32; 3], s: [f32; 3], a: f32) -> [f32; 3]

The composite of layer s with alpha a (times opacity) over opaque backdrop b.
