![]() ![]() Gets the native PixelFormat of the bitmap data. Gets the vertical dots per inch (dpi) of the image. Gets the horizontal dots per inch (dpi) of the image. Gets the Dispatcher this DispatcherObject is associated with. Gets the DependencyObjectType that wraps the CLR type of this instance. Gets a value that indicates whether the object can be made unmodifiable. Initializes a new instance of the BitmapSource class. The maximum size of a BitmapSource is 2^32 bytes (64 gigabytes) and the maximum image size is four gigapixels. The maximum height and width of an image is 2^16 pixels at 32 bits per channel * 4 channels. Windows Presentation Foundation (WPF) natively supports compression and decompression of bitmap (BMP), Graphics Interchange Format (GIF), Joint Photographics Experts Group (JPEG), Portable Network Graphics (PNG), and Tagged Image File Format (TIFF) images.įor bitmap decoding scenarios, BitmapSource uses automatic codec discovery, based on the installed codecs on the user's system. BitmapSource is not used to represent a multi-frame image or an animation. A BitmapSource could be a single frame in an image file that a decoder provides, or it could be the result of a transform that operates on a BitmapSource of its own. ' BitmapImage.UriSource must be in a BeginInit/EndInit block.īi.UriSource = New Uri("/sampleImages/cherries_larger.jpg", UriKind.RelativeOrAbsolute)īitmapSource is the basic building block of the Windows Presentation Foundation (WPF) imaging pipeline, conceptually representing a single, constant set of pixels at a certain size and resolution. BitmapImage.UriSource must be in a BeginInit/EndInit block.īi.UriSource = new Set the image source. The following code example uses a BitmapSource derived class, BitmapImage, to create a bitmap from an image file and use it as the source of an Image control.
