Methods

impl ColorType

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

Create color mode with given type and bitdepth

fn channels(&self) -> u8

channels * bytes per channel = bytes per pixel

Trait Implementations

impl Copy for ColorType

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, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Eq for ColorType

impl PartialEq for ColorType

fn eq(&self, __arg_0: &ColorType) -> bool

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