Crate img_parts

img-parts

The img-parts crate provides a low level api for reading and writing containers from various image formats.

It currently supports Jpeg, Png and RIFF (with some helper functions for WebP).

Reading and writing raw ICCP and EXIF metadata

use std::fs::{self, File};

use img_parts::jpeg::Jpeg;
use img_parts::{ImageEXIF, ImageICC};

let input = fs::read("img.jpg")?;
let output = File::create("out.jpg")?;

let mut jpeg = Jpeg::from_bytes(input.into())?;
let icc_profile = jpeg.icc_profile();
let exif_metadata = jpeg.exif();

jpeg.set_icc_profile(Some(another_icc_profile.into()));
jpeg.set_exif(Some(new_exif_metadata.into()));
jpeg.encoder().write_to(output)?;

Modifying chunks

use std::fs::{self, File};

use img_parts::jpeg::{markers, Jpeg, JpegSegment};
use img_parts::Bytes;

let input = fs::read("img.jpg")?;
let output = File::create("out.jpg")?;

let mut jpeg = Jpeg::from_bytes(input.into())?;

let comment = Bytes::from("Hello, I'm writing a comment!");
let comment_segment = JpegSegment::new_with_contents(markers::COM, comment);
jpeg.segments_mut().insert(1, comment_segment);

jpeg.encoder().write_to(output)?;
