Enum jpeg_decoder::ColorTransform

#[non_exhaustive]
pub enum ColorTransform {
    None,
    Unknown,
    Grayscale,
    RGB,
    YCbCr,
    CMYK,

Describes the colour transform to apply before binary data is returned

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.

None

No transform should be applied and the data is returned as-is.

Unknown

Unknown colour transformation

Grayscale

Grayscale transform should be applied (expects 1 channel)

RGB

RGB transform should be applied.

YCbCr

YCbCr transform should be applied.

CMYK

CMYK transform should be applied.

YCCK

YCCK transform should be applied.

JcsBgYcc

big gamut Y/Cb/Cr, bg-sYCC

JcsBgRgb

big gamut red/green/blue, bg-sRGB

Trait Implementations

impl Clone for ColorTransform

fn clone(&self) -> ColorTransform

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ColorTransform

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

Formats the value using the given formatter.

impl Hash for ColorTransform

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ColorTransform

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

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

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

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