Expand description

GIF file decoder

Can be converted to one of three Iterators:

Example: Get a Raster from a GIF

use gift::Decoder;

// ... open a `File` as "gif"
if let Some(step) = Decoder::new(gif).into_steps().next() {
    // was there a decoding error?
    let step = step?;
    let raster = step.raster();
    // ... work with raster
}
