Trait Implementations§

Source§

impl Clone for RGB

Source§

fn clone(&self) -> RGB

Returns a copy of the value. Read more
1.0.0 · Source§

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

Source§

impl ColourModel for RGB

Source§

fn channels() -> usize

Source§

impl Debug for RGB

Source§

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

Source§

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

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.

Source§

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.
Source§

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

Given a filename decode an image performing any necessary conversions.
Source§

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

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.

Source§

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

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

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.
