"Ayin" is an open-source photo editing software available on Windows, Linux, and MacOS (Only a Windows build is available now on GitHub but you can compile it yourself to other platforms) with an interactive real-time graphical user interface.
Feel free to use and study the source code of Ayin, it's available on GitHub under the GPLv3 open-source license.
I've made this project in part of the Winged Dragon Competition at the Faculty of Computers and Artificial Intelligence (FCAI-CU) Cairo University.
I've used ImGui, SDL2, and OpenGL (for image rendering, not processing)
A showcase video in Arabic is available, showing the functionalities of Ayin: https://youtu.be/ogkteQkJb0I
Any feedback is much appreciated, thank you!
