我試圖在WPF應用程序中顯示來自Kinect的攝像頭源。但是,圖像顯示爲空白。將圖像源綁定到BitmapSource時,圖像保持空白
下面是我在我的Kinect類中的一個片段,它全部正確啓動,並且BitmapSource似乎創建正常。
public delegate void FrameChangedDelegate(BitmapSource frame);
public event FrameChangedDelegate FrameChanged;
//this event is fired by the kinect service, and fires correctly
void sensor_AllFramesReady(object sender, AllFramesReadyEventArgs e)
{
using (ColorImageFrame colorFrame = e.OpenColorImageFrame())
{
if (colorFrame == null)
{
return;
}
byte[] pixels = new byte[colorFrame.PixelDataLength];
colorFrame.CopyPixelDataTo(pixels);
int stride = colorFrame.Width * 4;
BitmapSource newBitmap = BitmapSource.Create(colorFrame.Width, colorFrame.Height,
96, 96, PixelFormats.Bgr32, null, pixels, stride);
counter++;
//below is the call to the delegate
if (FrameChanged != null)
{
FrameChanged(newBitmap);
}
}
}
這是我在我的ViewModel。
void kinectService_FrameChanged(BitmapSource frame)
{
image = frame;
}
BitmapSource image;
public BitmapSource Image
{
get { return this.image; }
set
{
this.image = value;
this.OnPropertyChanged("Image");
}
}
以下是我的XAML視圖。
<Image Canvas.Left="212" Canvas.Top="58" Height="150" Name="image1" Stretch="Fill" Width="200" Source="{Binding Path=Image}"/>
所有的事件和屬性似乎都被更新。我究竟做錯了什麼?
嘗試FrameChanged:this.Image = frame – 2012-03-07 17:29:18
