Struct WebPContainer 

pub struct WebPContainer {
    pub encoding: WebPEncoding,
    pub features: Option<Vp8xFeatures>,
    pub chunks: Vec<RiffChunk>,
}

A fully parsed WebP RIFF container.

Fields

encoding: WebPEncoding

The encoding type (lossy, lossless, or extended).

features: Option<Vp8xFeatures>

VP8X feature flags, present only for extended format.

chunks: Vec<RiffChunk>

All chunks in the container, in order.

Implementations

impl WebPContainer

pub fn parse(data: &[u8]) -> CodecResult<Self>

Parse a WebP file from a byte slice.

Validates the RIFF header and iterates through all chunks.

pub fn bitstream_chunk(&self) -> Option<&RiffChunk>

Find the VP8 or VP8L bitstream chunk.

For simple files, this is the first (and only) chunk. For extended files, this searches for the first VP8/VP8L chunk.

pub fn alpha_chunk(&self) -> Option<&RiffChunk>

Find the alpha chunk (ALPH), if present.

pub fn icc_chunk(&self) -> Option<&RiffChunk>

Find the ICC profile chunk, if present.

pub fn exif_chunk(&self) -> Option<&RiffChunk>

Find the EXIF metadata chunk, if present.

pub fn xmp_chunk(&self) -> Option<&RiffChunk>

Find the XMP metadata chunk, if present.

pub fn anim_chunk(&self) -> Option<&RiffChunk>

Find the animation parameters chunk, if present.

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

Collect all animation frame chunks.

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

Get canvas dimensions.

For VP8X extended format, uses the canvas size from the header. For simple lossy, parses the VP8 frame header. For simple lossless, parses the VP8L signature header.
