Question

我正在尝试使用Kinect SDK在WPF中开发基本的照片捕获应用程序。在Kinect_ColorFrameReady事件处理程序中捕获帧看起来很容易，但我想要做的是在用户说出已经在我的Grammar.xml中定义的“Capture”时捕获帧。然后我想用像bmp，jpeg这样的图像扩展名来保存它...我应该在下面的代码中的注释行中做什么：

private void speechRecognized(object sender, SpeechRecognizedEventArgs e)
{
        recognizedWord = e.Result.Semantics.Value.ToString();

        if (recognizedWord == "Capture")
        {
            // Capture rgb frame?
        }
}

您可以让WriteableBitmap用于显示存储为全局变量的图像。

WriteableBitmap image;

... //write/display bitmap

private void speechRecognized(object sender, SpeechRecognizedEventArgs e)
{
    recognizedWord = e.Result.Semantics.Value.ToString();

    if (recognizedWord == "Capture")
    {
        using (FileStream stream5 = new FileStream(filename, FileMode.Create))
        {
            JpgBitmapEncoder encoder5 = new JpgBitmapEncoder();
            encoder5.Frames.Add(BitmapFrame.Create(image));
            encoder5.Save(stream5);
            stream5.Close();
        }
    }
}

如何在speechRecognized事件处理程序中保存rgb框架？
