# tinygif
A tiny gif decoder written in `no_std` Rust.
This crate requires about 20kB of memory to decode a gif.
- [x] basic decoding
- [x] frame iterator
- [ ] interlace support
- [ ] fails on some highly compressed gifs: **Change table size in DecodingDict**
## Usage
`Instant` and `Timer` are from Embassy framework, you can replace them with your own delay implementation.
```rust
let image = tinygif::Gif::::from_slice(include_bytes!("../Ferris-240x240.gif")).unwrap();
loop {
for frame in image.frames() {
let start = Instant::now();
frame.draw(&mut display).unwrap();
let remain_delay = ((frame.delay_centis as u64) * 10).saturating_sub(start.elapsed().as_millis());
Timer::after_millis(remain_delay).await;
// Or, draw at given offset
// use embedded_graphics::prelude::DrawTargetExt;
// frame.draw(&mut display.translated(Point::new(30, 50))).unwrap();
}
}
```
