How It Works

When you take a photo on your BlackBerry Z10 or Q10 the image is stored with an orientation value of 6 (right-side up). If you have an app that needs to use these photos, they will be displayed sideways in your app. Naturally you're probably thinking "That's fine, I'll just rotate all my photos so that they are the right orientation". That's fine, but what if the user wants to open a photo that is not saved right-side up? This is where detecting the images EXIF data comes in to play.

This sample is extremely easy to use. We are simply picking a photo (in this case, from the camera), detecting what the EXIF.orientation value is, and rotating the image accordingly.

The included EXIF Reader plugin has been modified to retrieve the EXIF data from a sepcified image object.
