Defines the color mixing function for a blend operation.

Variants

Normal = 0

Default attribute which specifies no blending. The blending formula simply selects the source color.

Multiply = 1

Source color is multiplied by the destination color and replaces the destination.

Screen = 2

Multiplies the complements of the backdrop and source color values, then complements the result.

Overlay = 3

Multiplies or screens the colors, depending on the backdrop color value.

Darken = 4

Selects the darker of the backdrop and source colors.

Lighten = 5

Selects the lighter of the backdrop and source colors.

ColorDodge = 6

Brightens the backdrop color to reflect the source color. Painting with black produces no change.

ColorBurn = 7

Darkens the backdrop color to reflect the source color. Painting with white produces no change.

HardLight = 8

Multiplies or screens the colors, depending on the source color value. The effect is similar to shining a harsh spotlight on the backdrop.

SoftLight = 9

Darkens or lightens the colors, depending on the source color value. The effect is similar to shining a diffused spotlight on the backdrop.

Difference = 10

Subtracts the darker of the two constituent colors from the lighter color.

Exclusion = 11

Produces an effect similar to that of the Difference mode but lower in contrast. Painting with white inverts the backdrop color; painting with black produces no change.

Hue = 12

Creates a color with the hue of the source color and the saturation and luminosity of the backdrop color.

Saturation = 13

Creates a color with the saturation of the source color and the hue and luminosity of the backdrop color. Painting with this mode in an area of the backdrop that is a pure gray (no saturation) produces no change.

Color = 14

Creates a color with the hue and saturation of the source color and the luminosity of the backdrop color. This preserves the gray levels of the backdrop and is useful for coloring monochrome images or tinting color images.

Luminosity = 15

Creates a color with the luminosity of the source color and the hue and saturation of the backdrop color. This produces an inverse effect to that of the Color mode.

Trait Implementations

impl CheckedBitPattern for Mix

type Bits = u8

Self must have the same layout as the specified Bits except for the possible invalid bit patterns being checked during is_valid_bit_pattern.

fn is_valid_bit_pattern(bits: &u8) -> bool

If this function returns true, then it must be valid to reinterpret bits as &Self.

impl Clone for Mix

fn clone(&self) -> Mix

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Contiguous for Mix

const MIN_VALUE: u8

The lower inclusive bound for valid instances of this type.

const MAX_VALUE: u8

The upper inclusive bound for valid instances of this type.

type Int = u8

The primitive integer type with an identical representation to this type.

fn from_integer(value: Self::Int) -> Option<Self>

If value is within the range for valid instances of this type, returns Some(converted_value), otherwise, returns None.

fn into_integer(self) -> Self::Int

Perform the conversion from C into the underlying integral type. This mostly exists otherwise generic code would need unsafe for the value as integer

impl Debug for Mix

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

Formats the value using the given formatter.

impl From<Mix> for BlendMode

fn from(mix: Mix) -> BlendMode

Converts to this type from the input type.

impl PartialEq for Mix

fn eq(&self, other: &Mix) -> 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 Zeroable for Mix

fn zeroed() -> Self

Calls zeroed.

impl Copy for Mix

impl Eq for Mix

impl NoUninit for Mix

impl StructuralPartialEq for Mix
