CAN I ACCESS ALL THOSE PIXELS?

CAN I EFFICIENTLY HANDLE THEM?

WHAT’S IN IT FOR ME?

SHOW ME … THE PIXELS!

By default, the PhotoCaptureDevice doesn’t expose the 34 or 38 megapixels resolutions.

DO YOU NEED IT?

Without any changes, your app will capture awesome 5 MP images.

captureResolution = PhotoCaptureDevice.GetAvailableCaptureResolutions(SENSOR_LOCATION).Last();var deviceName = Microsoft.Phone.Info.DeviceStatus.DeviceName; if (deviceName.Contains("RM-875") || deviceName.Contains("RM-876") || deviceName.Contains("RM-877")) { // We now knows that the application runs on a Lumia 1020 captureResolution = new Windows.Foundation.Size(7712, 4352); // 16:9 ratio } _device = await PhotoCaptureDevice.OpenAsync(SENSOR_LOCATION, captureResolution);

DO YOU REALLY WANT IT?

Applications must to be aware of high resolution in order to use it

• High res images requires special attention and may break other applications.

BE NICE TO YOUR NEIGHBOURS!

• Don’t save full resolution images to the camera roll.

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

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

GOOD TO KNOW

Easy to use …EditingSession session = new EditingSession(jpegData);

session.AddFilter(FilterFactory.CreateCartoonFilter(true));session.AddFilter(FilterFactory.CreateFogFilter());

await session.RenderToImageAsync(FilteredImage);
