Remarks
Many image formats, like JPEG and TIFF, allow a small sized thumbnail of the full image to be embedded within a frame. If the image does not contain a thumbnail, then this operation will fail with HRESULT WINCODEC_ERR_CODECNOTHUMBNAIL. If it exists, the EXIF orientation flag on the frame is automatically applied to the thumbnail before it is returned.
