How to do it...

To prepare the example that loads an image and converts it into grayscale, perform the following steps:

  1. Install the WriteableBitmapEx library using the NuGet Package Manager.

  2. Add the Image.jpg file to the Assets directory.

  3. Place the Image control where the grayscale photo will be shown on the page by adjusting the content of the MainPage.xaml file, as follows:
