fastexif

Exif metadata reader with convenience wrappers for GPS/time tags.

Examples

Read GPS location

let data = ...;
let options = Default::default();
let tiff = fastexif::parse(&data)?.into_entry_map(options)?;
if let Some(gps) = tiff.get_gps_info() {
    let location = (gps.longitude(), gps.latitude(), gps.altitude());
    println!("GPS location: {location:?}");
}

Convert Exif tags to JSON

let data = ...;
let options = Default::default();
let tiff = fastexif::parse(&data)?.into_entry_map(options)?;
println!("{}", serde_json::to_string_pretty(&tiff)?);

Read Apple-specific tags (experimental)

use fastexif::exif::MakerNote;

let data = ...;
let options = Default::default();
let tiff = fastexif::parse(&data)?.into_entry_map(options)?;
if let Some(exif) = tiff.get_exif() {
    if let Some(MakerNote::Apple(apple)) = exif.get_maker_note() {
        // `Front` or `Back`.
        println!("Camera type: {:?}", apple.get_camera_type());
    }
}
