Enum ColorFormat 

#[repr(u8)]
pub enum ColorFormat {
    Gray = 0,
    RGB = 2,
    Palette = 3,
    GrayA = 4,
    RGBA = 6,
}

A color format, which specifies how the bytes represent the pixels.

Variants

Gray = 0

A format encoding only the luminosity of each pixel.

Valid bit depths are 1, 2, 4, 8 and 16 bits.

RGB = 2

A format encoding the red, green, then blue components of each pixel.

Valid bit depths are 8 and 16 bits.

Palette = 3

A single-channel format encoding the index of each pixel in a palette.

If you use this format, you probably want to also use meta::palette or meta::palette_alpha before writing any image data, because otherwise, the decoder probably won’t know what each index represents.

Valid bit depths are 1, 2, 4 and 8 bits.

GrayA = 4

The same as Gray, but with an alpha channel added to the end.

Valid bit depths are 8 and 16 bits.

RGBA = 6

The same as RGB, but with an alpha channel added to the end.

Valid bit depths are 8 and 16 bits.

Implementations

impl ColorFormat

pub fn channels(self) -> usize

The number of components in each pixel.

Trait Implementations

impl Clone for ColorFormat

fn clone(&self) -> ColorFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColorFormat

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

Formats the value using the given formatter.

impl Hash for ColorFormat

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 ColorFormat

fn eq(&self, other: &ColorFormat) -> 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.
