Struct WebpImage 

pub struct WebpImage {
    pub width: u32,
    pub height: u32,
    pub frames: Vec<WebpFrame>,
    pub metadata: WebpFileMetadata,
    pub anim_background_rgba: Option<[u8; 4]>,
    pub anim_loop_count: Option<u16>,
}

A fully decoded WebP file: one frame for a still image, N frames for an animation, plus the file-level metadata and animation parameters.

This is the published-API decode result. The single most important consumer property is the flat-buffer shape of each WebpFrame::rgba: width * height * 4 tightly packed [R, G, B, A] bytes, no per-row stride padding, so it drops straight into image::ImageBuffer::from_raw(width, height, rgba).

Fields

width: u32

Canvas width in pixels (the §2.7.1 VP8X canvas width for an extended file, or the §3.4 / RFC 6386 §9.1 image-header width for a simple-lossless / simple-lossy file). Matches the first frame’s width for a single-frame image.

height: u32

Canvas height in pixels — see Self::width for the spec citation.

frames: Vec<WebpFrame>

Decoded frames. A still image yields exactly one frame; an animation yields one per ANMF chunk (animation decode is not rebuilt yet — see decode_webp).

metadata: WebpFileMetadata

File-level metadata (ICC / Exif / XMP), each None when absent.

anim_background_rgba: Option<[u8; 4]>

The §2.7.1.1 ANIM background colour as [R, G, B, A], or None for a non-animated file.

anim_loop_count: Option<u16>

The §2.7.1.1 ANIM loop count (0 = loop forever), or None for a non-animated file.

Trait Implementations

impl Clone for WebpImage

fn clone(&self) -> WebpImage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WebpImage

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

Formats the value using the given formatter.

impl Eq for WebpImage

impl PartialEq for WebpImage

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