Crate jpeg_decoder
source ·Expand description
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();
Structs
- JPEG decoder
- Represents metadata of an image.
Enums
- Represents the coding process of an image.
- Describes the colour transform to apply before binary data is returned
- Errors that can occur while decoding a JPEG image.
- An enumeration over combinations of color spaces and bit depths a pixel can have.
- An enumeration over JPEG features (currently) unsupported by this library.
