Crate jpegxl_rs

Overview

A safe JPEGXL wrapper over jpeg-xl library. Check out the original library and the bindings.

Usage

Decoding

use jpegxl_rs::decoder::*;
let sample = std::fs::read("test/sample.jxl")?;
let mut decoder: JXLDecoder<u8> = decoder_builder().build();
let (info, buffer) = decoder.decode(&sample)?;

Set output pixel paramaters

// Pixel type is set by type parameter
use jpegxl_rs::{decoder::*, Endianness};
let mut decoder: JXLDecoder<u16> = decoder_builder()
                                    .num_channels(3)
                                    .endian(Endianness::Big)
                                    .align(8)
                                    .build();

Encoding

use image::io::Reader as ImageReader;
let sample = ImageReader::open("test/sample.png")?.decode()?.to_rgba16();
let mut encoder = encoder_builder().build();
let buffer: Vec<u8> = encoder.encode(
                        &sample,
                        sample.width() as u64,
                        sample.height() as u64
                      )?;

image crate integration

The integration is enabled by default. If you don't need it, disable with-image feature.
