GIFt

A Rust library for encoding and decoding GIF images.

Documentation

https://docs.rs/gift

Decoding

use gift::Decoder;
use std::fs::File;
use std::io::BufReader;

let gif = BufReader::new(File::open("example.gif")?);
for step in Decoder::new(gif) {
    // was there a decoding error?
    let raster = step?.raster();
    // ... work with raster
}

Encoding

use gift::{Encoder, Step};
use pix::{gray::Gray8, Palette, Raster, rgb::SRgb8};
use std::error::Error;
use std::io::Write;

fn encode<W: Write>(mut w: W) -> Result<(), Box<dyn Error>> {
    let mut raster = Raster::<Gray8>::with_clear(4, 4);
    // ... initialize raster ...
    let mut palette = Palette::new(2);
    // ... initialize palette ...
    let step = Step::with_indexed(raster, palette);
    let mut enc = Encoder::new(&mut w).into_step_enc();
    enc.encode_step(&step)?;
    Ok(())
}

NOTE: building a palette from 24- or 32-bit rasters is not yet implemented.

Utility

The library comes with a gift command-line utility, which can show the blocks within GIF files.

cargo install gift --features=cmd

NOTE: This utility is a work-in-progress, and some features are not implemented.
