![]() ![]() ![]() This may seem like a commonplace thing now that several electric vehicle makers are offering long-range EV’s, but in 2013 that idea was poppycock that any electric car could make such a long trip. The BC-BC event featured a sort of race from British Columbia to Baja California, showcasing the ability of electric vehicles to travel long distances even in 2013. This picture was shot in July 2013, during the second BC-BC endurance run for electric vehicles. There are several metadata formats available: Since there are several packages for this purpose, we’ll show small example scripts for each. It’s up to you how you’ll use this data, but the first step is knowing how to retrieve this data. The rationale for accessing this data, is we need to use it, to help drive an application, to show some data to the user, or anything else. As we’ll see there is a long list of possible data to store in images. Or, we could store descriptions, captions, or other text items, that are meant to be displayed by a content management system. Much of it is data about the camera, the exposure, and even the geographical location, but it is possible to attach arbitrary information.Ī possible use is sorting images by the location where they were shot. But, there is other non-visual data items that can be included in an image. The pixels are the visual part of the image that we see. What, precisely, is image metadata? It is the extra data carried in the image file beyond the pixels. Our goal in this article is learning about accessing image metadata in a Node.js program. What we’ll do in this tutorial is explore reading metadata in Node.js. For example, a static website generator platform, like AkashaCMS, might use metadata stored in images such as to automatically provide captions, or tooltip text. While there are fancy GUI applications for dealing with this data, we sometimes need to process it in our Node.js programs. We can store extra data inside images, such as geolocation coordinates, text strings, and more.
