Represents a container for bitmap frames. Each bitmap frame is a BitmapSource. This abstract class provides a base set of functionality for all derived decoder objects.
Assembly: PresentationCore (in PresentationCore.dll)
is not a BitmapFrame itself; rather, it is a container for BitmapFrame objects. Each BitmapFrame in the container can potentially have different attributes, including different sizes, resolutions, or palettes.
Unless a specific codec is selected, Windows Presentation Foundation (WPF) uses automatic run-time discovery to identify the format of an image and match it with the appropriate codec. This discovery process allows a codec developed by an independent software vendor (ISV) to be automatically discoverable by the system. To select a specific codec, the derived or BitmapEncoder, such as the TiffBitmapDecoder class, should be used.
Tagged Image File Format (TIFF) and Graphics Interchange Format (GIF) are the only implemented image formats that support multiple frames.
The following example demonstrates how to use the Create(Uri, BitmapCreateOptions, BitmapCacheOption) method to create a decoder for a given image. The first BitmapFrame of the image is used as the source of an Image control.
The following code example demonstrates how to use the built in TiffBitmapDecoder to open and decode a Tagged Image File Format (TIFF) bitmap. The resulting BitmapSource is used as the Source of an Image element.
