BitmapImage()
Initializes a new instance of the BitmapImage class.
public:
BitmapImage();public BitmapImage ();Public Sub New ()Remarks
BitmapImage implements the ISupportInitialize interface to optimize initialization on multiple properties. To initialize a BitmapImage created using this constructor, you must perform property initialization between BeginInit and EndInit calls.
Applies to
BitmapImage(Uri)
Initializes a new instance of the BitmapImage class by using the supplied Uri.
public:
BitmapImage(Uri ^ uriSource);public BitmapImage (Uri uriSource);new System.Windows.Media.Imaging.BitmapImage : Uri -> System.Windows.Media.Imaging.BitmapImagePublic Sub New (uriSource As Uri)Parameters
- uriSource
- Uri
The Uri to use as the source of the BitmapImage.
Exceptions
The uriSource parameter is null.
The file specified by the uriSource parameter is not found.
Remarks

- uriSource
- Uri
The Uri to use as the source of the BitmapImage.
- uriCachePolicy
- RequestCachePolicy
The RequestCachePolicy that specifies the caching requirements for images that are obtained using HTTP.
