Enum tetra::graphics::BlendAlphaMode

pub enum BlendAlphaMode {
    Multiply,
    Premultiplied,
}

How to treat alpha values when blending colors.

Variants

Multiply

The RGB components of the color are multiplied by the alpha component before blending with the target.

This is the default behaviour.

Premultiplied

The RGB components of the color are not multiplied by the alpha component before blending with the target.

For this mode to work correctly, you must have multiplied the RGB components of the colour by the alpha component at some previous point in time (e.g. in your code, or in your asset pipeline).

Trait Implementations

impl Clone for BlendAlphaMode

fn clone(&self) -> BlendAlphaMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for BlendAlphaMode

impl Debug for BlendAlphaMode

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

Formats the value using the given formatter.

impl Default for BlendAlphaMode

fn default() -> BlendAlphaMode

Returns the “default value” for a type.

impl Eq for BlendAlphaMode

impl PartialEq<BlendAlphaMode> for BlendAlphaMode

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use]pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
