    10 This sub-format was designed to support a lossy compression-method.

    11 It is based completely on the JPEG specification. It adds the high-compression

    12 ratios of JPEG for photographic images.

    14 As a member of the Network Graphics family, JNG was deemed adequate as a

    15 stand-alone format as it extends the JPEG format with color-correction and

    16 transparency features.
