Struct webp_animation::Decoder [−][src]
pub struct Decoder<'a> { /* fields omitted */ }
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)); }
