I'm trying to show a camera feed from a Kinect in a WPF application. However, the image appears blank.
Below is a snippet of what I have in my Kinect class, this all fires correctly, and the BitmapSource appears to be created fine.
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);
}
}
}
Here is what I have in my ViewModel.
void kinectService_FrameChanged(BitmapSource frame)
{
image = frame;
}
BitmapSource image;
public BitmapSource Image
{
get { return this.image; }
set
{
this.image = value;
this.OnPropertyChanged("Image");
}
}
And below is what I have in my XAML View.
<Image Canvas.Left="212" Canvas.Top="58" Height="150" Name="image1" Stretch="Fill" Width="200" Source="{Binding Path=Image}"/>
All of the events and property's seem to be updated. What am I doing wrong?
image = frame;
should be:
Image = frame;
otherwise your property change notification won't fire.
