Provides access to a metadata query writer that can write metadata to a bitmap image file.
Assembly: PresentationCore (in PresentationCore.dll)
Metadata that is associated with an image is data that describes the image but that is not necessary for display of the image. Each supported bitmap image format handles metadata differently, but the facility for reading and writing metadata is the same.
Windows Presentation Foundation (WPF) supports the following image metadata schemas: Exchangeable image file (Exif), tEXt (PNG Textual Data), image file directory (IFD), International Press Telecommunications Council (IPTC), and Extensible Metadata Platform (XMP).
The following code example demonstrates how to use the method to write metadata to a Portable Network Graphics (PNG) file.
After the metadata is written, the GetQuery method is used to read that data and emit it as a text string.
Windows 7, Windows Vista, Windows XP SP2, Windows Server 2008 R2, Windows Server 2008, Windows Server 2003
The .NET Framework and .NET Compact Framework do not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
