Enum png::ColorType

#[repr(u8)]
pub enum ColorType {
    Grayscale = 0,
    RGB = 2,
    Indexed = 3,
    GrayscaleAlpha = 4,
    RGBA = 6,
}

Describes the layout of samples in a pixel

Variants

Grayscale = 0

RGB = 2

Indexed = 3

GrayscaleAlpha = 4

RGBA = 6

Implementations

impl ColorType

pub fn samples(&self) -> usize

Returns the number of samples used per pixel of ColorType

pub fn from_u8(n: u8) -> Option<ColorType>

u8 -> Self. Temporary solution until Rust provides a canonical one.

Trait Implementations

impl Clone for ColorType

fn clone(&self) -> ColorType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ColorType

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

Formats the value using the given formatter.

impl PartialEq for ColorType

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