My memory of Windows Phone NoDo API set is pretty bleak. I distinctly remember presence of CameraCaptureTask and PhotoChooserTask. I think I used PhotoChooserTask with my first app Scribble. So what’s this post about ? well Photo / Camera options available on Windows Phone 8.
Since I started with the two tasks, they still exist in Windows Phone 8.
CameraCaptureTask: this fires the stock camera app – ability to navigate to camera roll and use other lens is blocked but otherwise it is the stock windows phone app. Tap to focus / capture or use dedicated shutter button. On capture you are presented with a preview and you have the option to accept or retake the capture.
PhotoChooserTask: this is a different beast. This opens photos hub and presents user with list of albums allowing user to select a photo. The Task has a parameter that toggles visibility of camera icon – ability to not just select a picture but also initiate CameraCaptureTask from within.
While both of these are very basic, let me point out that Instagram BETA still uses a layout very similar to Photochooser task and obviously uses Camera Capture Task.
Its very likely that Instagram could get away with murder. Most of us – 3rd party developers however do not have such luxury. We would be termed as lazy if not worse. And you might not want the stock camera UI. So what can you do ? I am still in old API mode so let me mention an API that was part of Mango – I don’t know if NoDo had it or not – I only used it after Mango public release in my Cool Camera app.
PhotoCamera Class: this class provides raw access to camera and exposes a few options like resolution, flash and focus. Apps render live view by means of using a video brush whose source is set to an instance of photo camera class. How to create a base camera app for Windows Phone provides a great sample to kick start camera app development using this class
Whilst this is a good start, the API is not extensive enough for anything beyond basic. In the next post, I will discuss PhotoCaptureDevice class. This class though simple, exposes enough API to create a full blown camera app allowing you to control every single aspect of camera. If you hardware supports it, you should be able to utilise it
