The libmng library supports decoding, displaying, encoding, and various other manipulations of Multiple-image Network Graphics (MNG) format image files. It uses the zlib(3) compression library, and optionally the JPEG library by the Independant JPEG Group (IJG) and/or lcms (little CMS), a color-management library by Marti Maria Saguar.
