gif-viewer

Simple and lightweight GIF-Viewer written in C

This software depends on SDL2. It is licensed with the MIT license.

You will probably have to use your own build system for now. I am using CMake. I have uploaded my own CMake file, but it may not work with your configuration.

Some of the examples I painted myself were made using GIMP. For the other examples and the specification text I do not claim copyright. These files are only included for educational purposes.

TODO

• Implement interlacing
• Fully parse all the extension blocks, right now there is only support for transparency and duration specified in the graphics control blocks
• Modularize the gif components, specifying a more clear interface with the library
