Enum MatrixCoefficients

#[non_exhaustive]
pub enum MatrixCoefficients {
    Rgb = 0,
    Bt709 = 1,
    Unspecified = 2,
    Bt601 = 6,
    Ycgco = 8,
    Bt2020Ncl = 9,
    Bt2020Cl = 10,
}

This is the format of color channels.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Rgb = 0

GBR (sRGB). This isn’t actually good for most RGB images. Use Bt709 for lossy and Ycgco for lossless.

Bt709 = 1

ITU-R BT1361

Unspecified = 2

Bt601 = 6

ITU-R BT601-6 525. This matches luma in JPEG’s YCbCr when used with sRGB transfer characteristics, but is a bit off for chroma.

Ycgco = 8

Bt2020Ncl = 9

ITU-R BT2020 non-constant luminance system

Bt2020Cl = 10

ITU-R BT2020 constant luminance system

Trait Implementations

impl Clone for MatrixCoefficients

fn clone(&self) -> MatrixCoefficients

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MatrixCoefficients

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

Formats the value using the given formatter.

impl PartialEq for MatrixCoefficients

fn eq(&self, other: &MatrixCoefficients) -> 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 MatrixCoefficients
