Imaging on Windows Phone 8

  1. 1. Toan Huynh Technical Evangelist Imaging on Windows Phone
  2. 2. Windows Phone 8 – Imaging on Windows Phone 8/14/2013Microsoft confidential2 • Lenses • Nokia Imaging SDK • Windows Phone Photo Extensibility
  3. 3. 8/14/2013Microsoft confidential3 Lenses
  4. 4. Creating a Lens • A Lens is a custom camera application which can be accessed from within the camera application • An application is flagged as a Lens application by setting a flag in the manifest and providing icons that can be used to browse for the Lens when the camera is in use • I’ve created a FunkyCamera lens application which I have registered in this way 4
  5. 5. Creating a Lens application • This text must be added to the WMAppManifest.xml file for the application, just after the <Tokens> section • There is no GUI for this alteration, you have to edit the XML directly <Extensions> <Extension ExtensionName="Camera_Capture_App" ConsumerID="{5B04B775-356B-4AA0-AAF8-6491FFEA5631}" TaskID="_default" /> </Extensions>
  6. 6. Adding the Lens Icons • Three Icons are required, one for each Windows Phone screen size • WVGA 173 × 173 AssetsLens.Screen-WVGA.png • 720p 259 × 259 AssetsLens.Screen-720p.png • WXGA 277 × 277 AssetsLens.Screen-WXGA.png • They are all placed in the Assets folder of the application • Use a transparent background to match the Windows Phone color scheme 8/14/20136
  7. 7. (add shader example) • Three Icons are required, one for each Windows Phone screen size • WVGA 173 × 173 AssetsLens.Screen-WVGA.png • 720p 259 × 259 AssetsLens.Screen-720p.png • WXGA 277 × 277 AssetsLens.Screen-WXGA.png • They are all placed in the Assets folder of the application • Use a transparent background to match the Windows Phone color scheme 8/14/20137
  8. 8. • You can also create an application that has an auto-upload behaviour for pictures that the user may take • The upload behaviour is a “resource intensive” background task • The application must set the extension shown above and display a settings page where the user can set authentication and upload options • This is a background process and therefore might not get to run Creating an Auto-Uploader for photos <Extensions> <Extension ExtensionName="Photos_Auto_Upload" ConsumerID="{5B04B775-356B-4AA0-AAF8-6491FFEA5632}" TaskID="_default" /> </Extensions>
  9. 9. 8/14/2013Microsoft confidential9 Nokia Imaging SDK
  10. 10. Nokia Imaging SDK • Early Beta version, makes some of the technologies that Nokia uses in its own imaging applications available to developers • Provides more than 50 pre-made filters and effects that have been specifically developed for mobile imaging, with speed and memory performance as key drivers • The SDK is super-fast, meticulous memory and code optimization • Allows access to any image data without decoding the whole image • Apply effects to high resolution images, without worrying about memory budget 10
  11. 11. Easy to use • Add a filter to your existing project with just a few lines of C#. • Support to be called from C++ code. • The filters can be chained to create more effects 11
  12. 12. Core concepts • Provided as a Windows Phone Runtime library • One of the key benefits of this is that developers can call the methods of the library from C#, Visual Basic, or C++. 12 1.An editing-session is created from an image. 2.One or several filters and effects are added to the session. 3.The editing-session is rendered into a bitmap or into a memory buffer. 4.Steps 2 and 3 are repeated if needed. 5.The editing-session is closed.
  13. 13. Editing-session code using Nokia.Graphics.Imaging; using (EditingSession editsession = new EditingSession(inputBuffer)) { // First add an antique effect editsession.AddFilter( FilterFactory.CreateAntiqueFilter()); // Then rotate the image editsession.AddFilter( FilterFactory.CreateFreeRotationFilter(35.0f, RotationScaleMode.FitInside) ); // Add more filters here if you want... // Finally, execute the filtering and render to a bitmap await editsession.RenderToBitmapAsync(outputBuffer); }
  14. 14. The libraries • Before starting to use the functionality provided by the Nokia Imaging SDK, the SDK libraries must be added to the project. • Two ways to add the libraries are proposed: • Using the Visual Studio NuGet package manager • Adding references to the project.
