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.
