Trait for an image encoder

Required methods

fn encode(&self, image: &Image<T, C>) -> Vec<u8>

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

Provided methods

fn encode_file<P: AsRef<Path>>(
    &self,
    image: &Image<T, 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.

Implementors

impl<T> Encoder<T, RGB> for PpmEncoder where
    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.
