Struct img_parts::webp::WebP

pub struct WebP { /* fields omitted */ }

The representation of a WebP image

Implementations

impl WebP

pub fn new(riff: RiffChunk) -> Result<WebP>

Construct a new WebP image from a RiffChunk.

Errors

This method returns a Error::WrongSignature if the content of the RiffChunk isn't a List or if the list's kind isn't "WEBP".

pub fn from_bytes(b: Bytes) -> Result<WebP>

Create a new WebP image from a Reader.

Errors

This method fails if the file signature doesn't match or if it is corrupted or truncated.

pub fn kind(&self) -> VP8Kind

Get the VP8Kind of this WebP.

pub fn dimensions(&self) -> Option<(u32, u32)>

Get the width and height of this WebP.

If this WebP has a VP8X chunk the dimension is the canvas size.

Otherwise the dimension is read from the VP8 bitstream header.

pub fn chunks(&self) -> &Vec<RiffChunk>

Get the chunks of this WebP.

pub fn chunks_mut(&mut self) -> &mut Vec<RiffChunk>

Get a mutable reference to the chunks of this WebP.

pub fn has_chunk(&self, id: [u8; 4]) -> bool

Check if there's a chunk with an id of id.

pub fn chunk_by_id(&self, id: [u8; 4]) -> Option<&RiffChunk>

Get the first chunk with an id of id.

pub fn chunks_by_id(&self, id: [u8; 4]) -> impl Iterator<Item = &RiffChunk>

Get every chunk with an id of id.

pub fn remove_chunks_by_id(&mut self, id: [u8; 4])

Remove every chunk with an id of id

pub fn len(&self) -> u32

Get the total size of the WebP once it is encoded.

Internally calls RiffChunk::len on the inner RiffChunk

pub fn encoder(self) -> ImageEncoder<RiffChunk>

Create an encoder for this WebP

Internally calls RiffChunk::encoder on the inner RiffChunk

Trait Implementations

impl Clone for WebP

fn clone(&self) -> WebP

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WebP

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

impl ImageEXIF for WebP

fn exif(&self) -> Option<Bytes>

fn set_exif(&mut self, exif: Option<Bytes>)

Overwrites the pre-existing EXIF metadata of this image.

impl ImageICC for WebP

fn icc_profile(&self) -> Option<Bytes>

Get the raw ICC Profile of this image

fn set_icc_profile(&mut self, profile: Option<Bytes>)

Overwrites the pre-existing ICC Profile of this image.

impl PartialEq<WebP> for WebP

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

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

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

This method tests for !=.
