how do you load a bitmapimage in wpf? Posted: Aug 3, 2012 7:44 AM

In a silverlight app, I have a BitmapImage defined as System.Windows.Media.Imaging.BitmapImage and it as a method called "SetSource" where I can set the source like this:

BitmapImage bitmap = new BitmapImage();
System.IO.Stream stream = _scene.GetStream();
if (stream == null) return;
bitmap.SetSource(stream);

In a WPF application I have also have a Bitmap image defined as System.Windows.Media.Imaging.BitmapImage but there is no SetSource method. How do I set the source in a WPF app like I do in a Silverlight app?

Also, it is a stream, not a string. It is not a URI. so "UriSource" method does not work. I tried this:

System.IO.Stream stream = _scene.GetStream();
if (stream == null) return;
BitmapImage bitmap = new BitmapImage();

bitmap.UriSource = new Uri(stream.ToString());

And at runtime, it threw an error tha URI cannot be determined. Is the URI an identifier for the intranet? Are you sure that this is not a silverlight thing? I am doing a WPF application

You can use the constructor to specify the UriSource

BitmapImage bmp = new BitmapImage(uriSource: new Uri());

Or you can use BitmapImage.StreamSource property to set the StreamSource

I'm trying this code, but I need some help to get it to work. I get some red lines below the code! I also wonder if I need to add some extra code inside the XAML code or is in enough with this:
