Struct PpmEncoder

pub struct PpmEncoder { /* private fields */ }

Encoder type for a PPM image.

Implementations

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 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 Debug for PpmEncoder

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

Formats the value using the given formatter.

impl Default for PpmEncoder

fn default() -> Self

Returns the “default value” for a type.

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 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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for PpmEncoder

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