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 Copy for RGB

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 Eq for RGB

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

Equality operator ==.

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

Inequality operator !=.

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.
