rexif

RExif is a native Rust crate, written to extract EXIF data from JPEG and TIFF images.

The crate also contains a sample binary called 'rexiftool' that accepts files as arguments and prints the EXIF data. It gives a rough idea on how to use the crate.

I am still filling in the implementation of most EXIF tags. Merge requests, comments and criticisms about coding style, information about uncovered EXIF tags, sample images that are not parsed correctly -- in short, any sort of feedback is welcome!

Example

match rexif::parse_file(&file_name) {
    Ok(exif) => {
        println!("{} {} exif entries: {}", file_name,
            exif.mime, exif.entries.len());

        for entry in &exif.entries {
            println!("    {}: {}",
                    entry.tag_readable,
                    entry.value_more_readable);
        }
    },
    Err(e) => {
        print!("Error in {}: {} {}", &file_name,
            Error::description(&e), e.extra).unwrap();
    }
}

The included tool refixtool accepts image file names as command-line parameters and prints EXIF data for them. The src/main.rs file is a good starting point to learn how to use the crate, then take a look into the ExifEntry struct.
