Windows Imaging Component

The Windows Imaging Component (WIC) provides an extensible framework for working with images and image metadata. WIC makes it possible to develop image codecs and get the same platform support as standard image formats. A single, consistent set of interfaces is used for all image processing, regardless of image format, so any application using the WIC gets automatic support for new image formats as soon as the codec is installed. The extensible metadata framework makes it possible for applications to read and write their own proprietary metadata directly to image files, so the metadata never gets lost or separated from the image.
