Decoding
The WIC decoding API are designed to be codec-independent and image decoding for WIC-enabled codecs is essentially the same. For more information about image decoding, see the Decoding Overview. For more information about using decoded image data, see the Bitmap Sources Overview.
The decoder does not support decoding raw sensor data and only supports files with a non-raw image representation embedded in an IFD with NewSubFileType equal to 1.
