Crate stegano_f5_jpeg_decoder 

This crate contains a JPEG decoder.

Examples

use stegano_f5_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 stegano_f5_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

Component

A JPEG image component (e.g., Y, Cb, Cr).

Decoder

JPEG decoder

FrameInfo

Information from the JPEG frame header (SOF marker).

ImageInfo

Represents metadata of an image.

RawCoefficients

Result of raw coefficient decoding — provides access to quantized DCT coefficients without dequantization or IDCT.

Enums

CodingProcess

Represents the coding process of an image.

ColorTransform

Describes the colour transform to apply before binary data is returned

EntropyCoding

The entropy coding method used in the JPEG image.

Error

Errors that can occur while decoding a JPEG image.

PixelFormat

An enumeration over combinations of color spaces and bit depths a pixel can have.

UnsupportedFeature

An enumeration over JPEG features (currently) unsupported by this library.
