BitmapFrame.CreateInPlaceBitmapMetadataWriter Method

When overridden in a derived class, creates an instance of InPlaceBitmapMetadataWriter, which can be used to associate metadata with a BitmapFrame.

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

public abstract InPlaceBitmapMetadataWriter CreateInPlaceBitmapMetadataWriter()
You cannot use methods in XAML.

Metadata can only be added or edited using the CreateInPlaceBitmapMetadataWriter if the image file contains enough room for the new metadata; otherwise, metadata can be added using the Metadata property.

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 = new System.IO.FileStream("smiley.png", FileMode.Open, FileAccess.ReadWrite, FileShare.ReadWrite);
PngBitmapDecoder pngDecoder = new 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();
