这个功能使用使用了 FormatConvertedBitmap(为BitmapSource提供像素格式转换功能)

 

代码如下:

 

public partial class MainWindow : Window

{     public MainWindow()     {         InitializeComponent();         Image img = new Image();         BitmapImage bitmapImage = new BitmapImage(new Uri("D:\\Face.jpg"));         FormatConvertedBitmap newFormatedBitmapSource = new FormatConvertedBitmap();         newFormatedBitmapSource.BeginInit();         newFormatedBitmapSource.Source = bitmapImage;         newFormatedBitmapSource.DestinationFormat = PixelFormats.Gray8;         newFormatedBitmapSource.EndInit();         img.Source = newFormatedBitmapSource;         this.Content = img;     } }
