(and later available in Windows XP Service Pack 3) for working with and processing digital images and image metadata. WIC enables application developers to perform image processing operations on any image format through a single set of common APIs, without requiring prior knowledge of specific image formats.

Features

Windows Imaging Component provides an extensible architecture for image codecs, pixel formats, and metadata, with automatic run-time discovery of new formats. It supports reading and writing of arbitrary metadata in image files, with the ability to preserve unrecognized metadata during editing. While working with images, it preserves high bit depth image data, up to 32 bits per channel, throughout the revamped high dynamic range image processing pipeline built into Windows Vista. Windows Imaging Component supports

With Windows 7 the WIC stack itself underwent a major overhaul and is now free-threaded, as are all the built-in and external codecs shipping with Windows. Being free-threaded is also a requirement for new codecs targeting Windows 7. Microsoft Expression Design's import and export capabilities are entirely based on WIC. Expression Media (now Phase One Media Pro) with Service Pack 1 and later also supports additional raw camera formats and HD Photo (now JPEG XR) using WIC.

Third-party support

As of 2018, few third-party imaging applications (image editors, image organizers and image viewers) utilize WIC. FastPictureViewer, a simple standalone third-party image viewer, supports standard image formats along with HD Photo and RAW camera formats (NRW, NEF, CR2, DNG) using WIC. An experimental WIC import
