如何將C＃WritableBitmap轉換為EmguCV / OpenCV Mat？

Question

我有一個WritableBitmap，我想將它轉換為EmguCV / OpenCV Mat。 我該怎么做呢？ 我已經從代碼在線嘗試了幾個鏈解決方案（WritableBitmap - > Bitmap - > Map），但我沒有找到任何有效的方法。 謝謝！

我覺得這很有效：

    public static Mat ToMat(BitmapSource source)
    {
        if (source.Format == PixelFormats.Bgra32)
        {
            Mat result = new Mat();
            result.Create(source.PixelHeight, source.PixelWidth, DepthType.Cv8U, 4);
            source.CopyPixels(Int32Rect.Empty, result.DataPointer, result.Step * result.Rows, result.Step);
            return result;
        }
        else if (source.Format == PixelFormats.Bgr24)
        {
            Mat result = new Mat();
            result.Create(source.PixelHeight, source.PixelWidth, DepthType.Cv8U, 3);
            source.CopyPixels(Int32Rect.Empty, result.DataPointer, result.Step * result.Rows, result.Step);
            return result;
        }
        else if (source.Format == PixelFormats.Pbgra32)
        {
            Mat result = new Mat();
            result.Create(source.PixelHeight, source.PixelWidth, DepthType.Cv8U, 4);
            source.CopyPixels(Int32Rect.Empty, result.DataPointer, result.Step * result.Rows, result.Step);
            return result;
        }
        else
        {
            throw new Exception(String.Format("Conversion from BitmapSource of format {0} is not supported.", source.Format));
        }
    }
