Description

libmodjpeg overlays a (masked) image onto an existing JPEG as losslessly as possible. Changes take effect only where the overlay is applied, and all modifications happen in the DCT domain, so the JPEG is never fully decoded and re-encoded. This package provides the shared library.

Built for Ubuntu.
