Struct RGB 

pub struct RGB;

RGB colour as intended by sRGB and standardised in IEC 61966-2-1:1999

Implementations

impl RGB

pub fn remove_gamma(v: f64) -> f64

Remove the gamma from a normalised channel

pub fn apply_gamma(v: f64) -> f64

Apply the gamma to a normalised channel

Trait Implementations

impl Clone for RGB

fn clone(&self) -> RGB

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ColourModel for RGB

fn channels() -> usize

Number of colour channels for a type.

impl Debug for RGB

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

Formats the value using the given formatter.

impl<T> Decoder<T, RGB> for PpmDecoder

where T: Copy + Clone + Num + NumAssignOps + NumCast + PartialOrd + Display + PixelBound + FromPrimitive,

Implements the decoder trait for the PpmDecoder.

The ColourModel type argument is locked to RGB - this prevents calling RGB::into::() unnecessarily which is unavoidable until trait specialisation is stabilised.

fn decode(&self, bytes: &[u8]) -> Result<Image<T, RGB>>

From the bytes decode an image, will perform any scaling or conversions required to represent elements with type T.

fn decode_file<P: AsRef<Path>>(&self, filename: P) -> Result<Image<T, C>>

Given a filename decode an image performing any necessary conversions.

impl<T, U> Encoder<T, U, RGB> for PpmEncoder

where U: Data<Elem = T>, T: Copy + Clone + Num + NumAssignOps + NumCast + PartialOrd + Display + PixelBound + FromPrimitive,

Implements the encoder trait for the PpmEncoder.

The ColourModel type argument is locked to RGB - this prevents calling RGB::into::() unnecessarily which is unavoidable until trait specialisation is stabilised.

fn encode(&self, image: &ImageBase<U, RGB>) -> Vec<u8>

Encode an image into a sequence of bytes for the given format

fn encode_file<P: AsRef<Path>>( &self, image: &ImageBase<U, C>, filename: P, ) -> Result<()>

Encode an image saving it to the file at filename. This function shouldn’t add an extension preferring the user to do that instead.

impl Hash for RGB

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 Ord for RGB

fn cmp(&self, other: &RGB) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for RGB

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

impl PartialOrd for RGB

fn partial_cmp(&self, other: &RGB) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
