c# - 带有 C# WPF 的 EMGU

Question

我正在尝试按照以下教程进行操作，但使用的是 WPF 而不是 Win Forms:

A Basic Program

WPF 不使用 PictureBox，而是使用 Image。

所以这里尝试加载一个 Image。

XAML

<Image x:Name="srcImg" Width="400" Height="300"></Image>

CS 尝试 1:

Image<Bgr, Byte> My_Image = new Image<Bgr, byte>(Openfile.FileName);
srcImg.Source = My_Image.ToBitmap();

错误信息

Cannot implicitly convert type 'System.Drawing.Bitmap' 
to 'System.Windows.Media.ImageSource'

CS 尝试 2:

Image<Bgr, Byte> My_Image = new Image<Bgr, byte>(Openfile.FileName);
srcImg.Source = new BitmapImage(My_Image);

错误信息

Error   1   The best overloaded method match for 'System.Windows.Media.Imaging.BitmapImage.BitmapImage(System.Uri)' has some invalid arguments  
Error   2   Argument 1: cannot convert from 'Emgu.CV.Image<Emgu.CV.Structure.Bgr,byte>' to 'System.Uri' 

知道我做错了什么吗？

Answer 1

问题已解决。要转换图像:

Image<Bgr, Byte> My_Image = new Image<Bgr, byte>(Openfile.FileName);
srcImg.Source = BitmapSourceConvert.ToBitmapSource(myImage);

BitmapSourceConvert 类:

public static class BitmapSourceConvert
{
    [DllImport("gdi32")]
    private static extern int DeleteObject(IntPtr o);

    public static BitmapSource ToBitmapSource(IImage image)
    {
        using (System.Drawing.Bitmap source = image.Bitmap)
        {
            IntPtr ptr = source.GetHbitmap();

            BitmapSource bs = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(
                ptr,
                IntPtr.Zero,
                Int32Rect.Empty,
                System.Windows.Media.Imaging.BitmapSizeOptions.FromEmptyOptions());

            DeleteObject(ptr);
            return bs;
        }
    }
}
