node-red-node-exif
==================

A <a href="http://nodered.org" target="_new">Node-RED</a> node to extract Exif information from JPEG images.

Install
-------

Run the following command in the root directory of your Node-RED install

    npm install node-red-node-exif


Usage
-----

Extracts <a href="http://en.wikipedia.org/wiki/Exchangeable_image_file_format">Exif</a> information from JPEG images.

This node expects an incoming JPEG image as a buffer. If Exif data is present, it extracts the data into a **msg.exif** object.

If the Exif data also contains location information this is extracted as **msg.location**.

**msg.payload** retains the original, unmodified image buffer.
