This sample demonstrates various techniques for displaying and manipulating images in your app using the Image control and the BitmapImage class.
Specifically, this sample covers:
- Displaying images packaged within an app.
- Displaying images from the file system that are selected by the user using the file picker. This scenario also demonstrates how to use the DecodePixelHeight and DecodePixelWidth properties to specify the display dimensions so that the image can decode the selected file efficiently.
- Displaying images using NineGrid margins, which enable you to scale the center of an image independently of its edges and corners.
- Using a WriteableBitmap to manipulate image pixels directly.
