Type for decode, encode, etc. Same as standard PNG color types.

Variants

GREY = 0

greyscale: 1, 2, 4, 8, 16 bit

RGB = 2

RGB: 8, 16 bit

PALETTE = 3

palette: 1, 2, 4, 8 bit

GREY_ALPHA = 4

greyscale with alpha: 8, 16 bit

RGBA = 6

RGB with alpha: 8, 16 bit

BGRA = 70

Not PNG standard, for internal use only. BGRA with alpha, 8 bit

BGR = 66

Not PNG standard, for internal use only. BGR no alpha, 8 bit

BGRX = 67

Not PNG standard, for internal use only. BGR no alpha, padded, 8 bit

Implementations

impl ColorType

pub fn bpp(&self, bitdepth: u32) -> u32

Bits per pixel

impl ColorType

pub fn to_color_mode(&self, bitdepth: c_uint) -> ColorMode

Create color mode with given type and bitdepth

pub fn channels(&self) -> u8

channels * bytes per channel = bytes per pixel

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

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.
