Struct webp_animation::Decoder [−][src]
pub struct Decoder<'a> { /* fields omitted */ }
Expand description
A decoder for webp animation data
Will take a webp buffer, and try to decode it to frame(s)
use webp_animation::prelude::*;
let buffer = std::fs::read("./data/animated.webp").unwrap();
let decoder = Decoder::new(&buffer).unwrap();
for frame in decoder.into_iter() {
assert_eq!(frame.dimensions(), (400, 400));
assert_eq!(frame.data().len(), 400 * 400 * 4); // w * h * rgba
}
See also documentation for the item produced by iterator: Frame
If image
feature is enabled, frames can be produced in [image::ImageBuffer
]
format:
use webp_animation::prelude::*;
for frame in decoder.into_iter() {
#[cfg(feature = "image")]
assert_eq!(frame.into_image().unwrap().dimensions(), (400, 400));
}

Construct a new decoder from webp buffer
Returns an Error
in case of a decoding failure (e.g. malformed input)
let buffer = std::fs::read("./data/animated.webp").unwrap();
let decoder = Decoder::new(&buffer).unwrap();
