A Nokia example demonstrating the use of the different filters of Nokia Imaging SDK with camera photos. This example app uses the camera and displays the viewfinder for taking a picture. The taken photo is then processed with the predefined filters. The filter properties can be manipulated and the changes can be seen in the preview image immediately. The processed image can be saved in JPEG format into the camera roll album. You can also select an existing photo and apply an effect to it.

This example application is hosted in GitHub: https://github.com/nokia-developer/filter-effects

1. Important classes

• AbstractFilter: The base class for the filters implemented by the application. This abstract class implements the preview image handling and defines the methods required to be implemented by the derived classes. The filters implemented by this example are:
• CarShowFilter: Lomo filter
• CartoonFilter: Cartoon filter
• EightiesPopSongFilter: Sketch filter
• SadHipsterFilter: Antique and lomo filter
• DataContext: A singleton class holding the references to image data.
• FilterPreviewPage: Manages the filters and implements image management including saving the image into the camera roll.
• FilterPropertiesControl: A custom user control for adjusting the filter settings. Each filter is responsible for populating the control compontents. This class is but a place holder with minimal implementation.
• MainPage: Implements the camera view finder and fetching saved images from the file system.

2. Compatibility

Compatible with Windows Phone 8 phones. The project is dependent on Nokia Imaging SDK. The example has been tested with Nokia Lumia 920 and Nokia Lumia 620. Developed with Visual Studio 2012 Express for Windows Phone 8.
