Free Lossless Image Format

FLIF is a lossless image format based on MANIAC compression. MANIAC (Meta-Adaptive Near-zero Integer Arithmetic Coding) is a variant of CABAC (context-adaptive binary arithmetic coding), where the contexts are nodes of decision trees which are dynamically learned at encode time. FLIF is copylefted free/libre software: you can redistribute it and/or modify it, provided that you share back. The decoder library libflif dec is released under a weaker, non-copyleft free software license: the Apache 2.0 license. The example application viewflif illustrates how to use the decode library. The example code in viewflif.c is in the public domain (Creative Commons CC0 1.0 Universal). Navigate to the FLIF/src directory and run make to compile everything, or make flif to build just the flif command line tool make libflif.so to build the LGPL'ed shared library make libflif dec.so to build the Apache licensed decode-only shared library make viewflif to build the example viewer (it depends on the decode library) Install Visual Studio (VS Community 2015 is free for open source projects) Open the build MSVC folder and double-click the dl make vs.bat file. This will download required libraries and run nmake to build flif.exe . Then, run in the command line: nmake libflif.dll to build the shared library nmake viewflif.exe to build the example viewer Poly FLIF - A javascript polyfill that allows you to use FLIF files in the browser. (Demo) UGUI: FLIF - A GUI that allows you to convert and view FLIF files. Ivy, the Taggable Image Viewer – An image viewer that supports FLIF via riff flifcrush - A brute-force FLIF optimizer. libflif.js – A javascript FLIF encoder and decoder. (Demo) flif.rs – A work-in-progress implementation of FLIF in Rust. FLIF Windows Codec – A plugin that allows you to decode and encode FLIF files in Windows aplications using the Windows Imaging Component (WIC) API. That allows e.g., to see the files in Windows PhotoViewer and Windows Explorer. FLIF Windows Plugin – This plugin enables decoding of FLIF images in applications which use the Windows Imaging Component API. In this way, FLIF images can be viewed in Windows Explorer like other common image formats. qt-flif-plugin – Enables Qt4 and Qt5 applications to load images in the FLIF image format. go-flif – Go FLIF Library Bindings.
