The Nokia Imaging SDK is a code library that helps developers work efficiently with images captured and stored by phones running Microsoft Windows Phone 8. In this Lumia App Labs webinar, we demonstrate the basics of working with the SDK. We provide a product overview and show you how to download the SDK and set up your development environment. We also demonstrate practical ways to apply effects and filters in your imaging apps; share tips and tricks to help you optimise app performance; and provide links to resources that you can use to make the most of your imaging-app projects.

For detailed documentation on the Nokia Imaging SDK, see http://developer.nokia.com/Resources/Library/Lumia/#!nokia-imaging-sdk.html

For more details about developing for Nokia Lumia smartphones visit http://www.developer.nokia.com/windowsphone

Check out details of the other Lumia App Labs, including the future schedule, here: http://www.developer.nokia.com/Develop/Windows_Phone/Learn/

LUMIA APP LAB #15: USING THE NOKIA IMAGING SDK

  1. 1. USING THE NOKIA IMAGING SDK LUMIA APP LABS #15 Berthier Lemieux Technology Wizard
  2. 2. Experts in imaging algorithms Acquired by Nokia, 24 July 2012 Their technology drives: Nokia Smart Camera Nokia Cinemagraph Nokia Creative studio SCALADO
  3. 3. Really fast preview of any region of the image Complete set of base filters and effects (52 filters). Combine them to generate more complex ones Highest performance and low memory consumption through RAJPEG technology (>15 patents) Cropping and JPEG compression parameter control NOKIA IMAGING SDK
  4. 4. Filter Effects, simple illustration of basics Example projects Real-time Filter Demo, live viewfinder stream processing Filter Explorer, complex illustration of various usage scenarios
  5. 5.  Apps developed with the SDK can be used on any Windows Phone 8, including non-Nokia, devices  The library is a WinPRT library. Routines are available via a C# interface as well as a C/C++ interface  Nokia Imaging SDK License Agreement: Free to use, attribution GOOD TO KNOW
  6. 6. List of filters and effects I
  7. 7. List of filters and effects II
  8. 8. List of filters and effects III
  9. 9. • Step 1: Include Nokia Imaging SDK Libraries into your project • Step 2 : Create EditingSession • Step 3 : Create and add filters to EditingSession • Step 4 : Use asynchronous methods RenderToImageAsync or RenderToJpegAsync to produce the final processed image General overview of required steps
  10. 10. • Use NuGet to install the SDK libraries. • Finalise the installation by : • Making sure thatin the Project’s Configuration Manager, only the X86 and ARM platformsare listed. The Any CPU platform should be removed • Save your project in VisualStudio • With an external editor (notepad, for example), edit the .csproj file to support both X86 and ARM platforms. In the <HintPath> elements, replace “X86” by “$(Platform)”. Step 1: Nokia Imaging SDK Libraries
  11. 11. Language Compiled to Runs in a virtual machine ? Processor architecture dependant? Managed code C#, VB Intermediate Language (MSIL) Yes (CLR) No Native code C++ Machine language No Yes PROCESSOR ARCHITECTURES Target Processor architecture type Emulator X86 Phone ARM You don’t need to know/understand this to use the SDK! Consider this as FYI.
  12. 12. • Create an Imaging SDK EditingSession using a compressed or uncompressed image: Step 2: Create EditingSession EditingSession session = new EditingSession(jpegData); • From a WriteableBitmap: EditingSession session = new EditingSession(sourceBitmap); • From a JPEG in a IBuffer: EditingSession session = await CreateEditingSessionAsync(stream); • From a Stream (from PhotoChooserTask):
  13. 13. • Use FilterFactory to create filters and effects • Use EditingSession methods to add filters and effects: Step 3: Create and add filters and effects session.AddFilter(FilterFactory.CreateCartoonFilter(true)); session.AddFilter(FilterFactory.CreateFogFilter()); • You can also use FilterGroup to add several filters and effects in one call
  14. 14. You can render the processed image to: • A XAML Image control: await session.RenderToImageAsync(FilteredImage); • A WriteableBitmap : await session.RenderToWriteableBitmapAsync(FilteredBitmap); • An IBuffer : IBuffer jpegOut = await session.RenderToJpegAsync(); Step 4: Produce final processed image
  15. 15. You found an error in the SDK, have suggestions, need help? Nokia Imaging discussion board: http://nokia.ly/DiBoImg You have developped an app with the SDK? We’d love to hear about it.

  17. 17. NOKIA IMAGING WIKI COMPETITION 2013Q3 Write a great tutorial, guide or an article with code which shows how to use the Nokia Imaging SDK or Camera and any other Windows Phone APIs related to imaging in useful, imaginative and innovative ways and/or provide the best feedback on the Nokia Imaging SDK. developer.nokia.com/Community/Wiki/
