    exif-reader

    A small EXIF image metadata reader.

    Usage

    npm install exif-reader
    
    var exif = require('exif-reader');
     
    // decode raw exif data from a buffer
    var metadata = exif(buf);

    Support is also built into jpg-stream for extracting EXIF data from JPEGs using this module.

    Resulting properties are grouped into four objects:

    • image: basic TIFF properties about the image
    • thumbnail: basic TIFF properties about the embedded thumbnail
    • exif: full exif data
    • gps: GPS/location data about the image
    • interoperability: interoperability information

    Not all of these properties will always be defined.

    Here is some example output:
