Crate jpeg_decoder

This crate contains a JPEG decoder.

Examples

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

let file = File::open("tests/reftest/images/extraneous-data.jpg").expect("failed to open file");
let mut decoder = Decoder::new(BufReader::new(file));
let pixels = decoder.decode().expect("failed to decode image");
let metadata = decoder.info().unwrap();

Get metadata from a file without decoding it:

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

let file = File::open("tests/reftest/images/extraneous-data.jpg").expect("failed to open file");
let mut decoder = Decoder::new(BufReader::new(file));
decoder.read_info().expect("failed to read metadata");
let metadata = decoder.info().unwrap();
