BitmapFrame Class

Represents image data returned by a decoder and accepted by encoders.

Namespace:  System.Windows.Media.Imaging
Assembly:  PresentationCore (in PresentationCore.dll)

public ref class BitmapFrame abstract : public BitmapSource, 
	IUriContext
This class is abstract; see Inheritance Hierarchy for derived non-abstract classes usable in XAML.

BitmapFrame provides additional functionality not defined by BitmapSource by providing access to the Thumbnail associated with a particular frame of an image. BitmapFrame also supports the writing of metadata information by using the Metadata property or the CreateInPlaceBitmapMetadataWriter method.

Any BitmapFrame returned from a decoder is always frozen. If you require a modifiable copy, you must first create a copy of the BitmapFrame by using the Clone method.

Only Tagged Image File Format (TIFF) and Graphics Interchange Format (GIF) format images support multiple frames.

The following code example demonstrates how to create a new BitmapSource by using a BitmapFrame.

No code example is currently available or this language may not be supported.

The following code example demonstrates how to use the BitmapFrame object to open a Portable Network Graphics (PNG) graphic and write metadata by using the CreateInPlaceBitmapMetadataWriter method.

Stream^ pngStream = gcnew FileStream("smiley.png", FileMode::Open, FileAccess::ReadWrite, FileShare::ReadWrite);
PngBitmapDecoder^ pngDecoder = gcnew PngBitmapDecoder(pngStream, BitmapCreateOptions::PreservePixelFormat, BitmapCacheOption::Default);
BitmapFrame^ pngFrame = pngDecoder->Frames[0];
InPlaceBitmapMetadataWriter^ pngInplace = pngFrame->CreateInPlaceBitmapMetadataWriter();
if (pngInplace->TrySave() == true)
{
   pngInplace->SetQuery("/Text/Description", "Have a nice day.");
}
pngStream->Close();
