Introduction to the Nokia Imaging SDK

5. What is the Nokia Imaging SDK?
• Includes more than 50 ready to use image processing filters
and effects, with various adjustment parameters
• Supports creation of totally custom filters
• Accessible from managed and native code
• Supports various source types: bitmaps, streams, files and
camera viewfinder
• Partial JPEG decoding - using RAJPEG technology, access
image data without decoding a whole JPEG image for a fast
previews, application of effects, rotation, and cropping of high
resolution images

16. Library contains three architectural building blocks:
• Image sources (such as bitmaps, streams, files)
• Effects (built-in or custom)
• Renderers (outputs bitmaps or files)
Combining these building blocks, developer creates
rendering pipeline
Once pipeline is created, it is possible to change filter
parameters, or their sequence.

17. General Overview of Required Steps
• Step 1: Include Nokia Imaging SDK Libraries into your project
• Step 2: Prepare source image: uncompressed image as WriteableBitmap,
AudioVideoCaptureDevice or compressed image as IBuffer, StorageFile
• Step 3: Create image source as instance of IImageSource
• Step 4: Instantiate and configure one or more effects, chained together
• Step 5: Create renderer with associated effect chain and target output
• Step 6: Use asynchronous methods RenderAsync in order to generate output
• Remember: official documentation is part of the Lumia Developer Library
http://developer.nokia.com/resources/library/Lumia/nokia-imaging-sdk.html

18. Nokia Imaging SDK Libraries
• Installable via NuGet Package Manager
• Make sure that in the Project’s Configuration
Manager, there will remain only X86 and ARM
platforms. “Any CPU” and “x64” platforms should
be removed
• Remember: Nokia Imaging SDK library is going to
be included into your final XAP file
