Struct ndarray_vision::format::netpbm::PpmEncoder

pub struct PpmEncoder { /* fields omitted */ }

Encoder type for a PPM image.

Methods

impl PpmEncoder

pub fn new() -> Self

Create a new PPM encoder or decoder

pub fn new_plaintext_encoder() -> Self

Creates a new PPM format to encode plain-text. This results in very large file sizes so isn't recommended in general use

Trait Implementations

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.

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

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

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.

impl Clone for PpmEncoder

fn clone(&self) -> PpmEncoder

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq<PpmEncoder> for PpmEncoder

fn eq(&self, other: &PpmEncoder) -> bool

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

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

This method tests for !=.

impl Eq for PpmEncoder

impl Copy for PpmEncoder

impl Default for PpmEncoder

fn default() -> Self

Returns the "default value" for a type.

impl Hash for PpmEncoder

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, 

Feeds a slice of this type into the given [Hasher].

impl Debug for PpmEncoder

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

Formats the value using the given formatter.
