Enum BlendMode 

pub enum BlendMode {
    Over,
    Add,
    Multiply,
    Screen,
    Darken,
    Lighten,
    Subtract,
}

Variants

Over

Premultiplied alpha-over (the baseline compositing contract; ADR 0040).

Add

Additive blending (used for glow/beam).

Multiply

Multiply blending (used for grain/darken overlays).

Screen

Screen blending (used for light overlays).

Darken

Channel-wise darken (min(dst, src) for color channels).

This mode is bounded and portable because it maps to a fixed-function blend operation (no destination sampling).

Lighten

Channel-wise lighten (max(dst, src) for color channels).

This mode is bounded and portable because it maps to a fixed-function blend operation (no destination sampling).

Subtract

Subtract (dst - src, clamped to [0, 1]) for color channels.

This mode is bounded and portable because it maps to a fixed-function blend operation (no destination sampling).

Implementations

impl BlendMode

pub const COUNT: usize = 7

pub const ALL: [BlendMode; 7]

pub const fn pipeline_index(self) -> usize

Trait Implementations

impl Clone for BlendMode

fn clone(&self) -> BlendMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BlendMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BlendMode

fn default() -> BlendMode

Returns the “default value” for a type.

impl PartialEq for BlendMode

fn eq(&self, other: &BlendMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for BlendMode

impl Eq for BlendMode

impl StructuralPartialEq for BlendMode
