Crate jpegli 

jpegli

Rust port of jpegli - an improved JPEG encoder and decoder.

jpegli provides enhanced compression quality compared to standard JPEG through advanced quantization, optional XYB color space, and other perceptual optimizations.

Features

• Baseline JPEG: Standard 8-bit JPEG encoding/decoding
• Progressive JPEG: Multi-scan progressive encoding
• XYB Color Space: Perceptually optimized color space for better quality
• Adaptive Quantization: Content-aware quantization for improved detail
• 16-bit Support: High bit-depth input/output

Example

use jpegli::{Encoder, ColorSpace, Quality};

let pixels: &[u8] = &[/* RGB data */];
let encoder = Encoder::new()
    .width(640)
    .height(480)
    .color_space(ColorSpace::Rgb)
    .quality(Quality::from_distance(1.0))
    .build()?;

let jpeg_data = encoder.encode(pixels)?;
