Graphic 2d Output for C++

About

ids::gout is library to put pixels on the screen.

it's very easy to use!

//resolution  : width and height
const auto resolution = ids::resolution{.width=800,.height=600};

//configure the window
ids::gout.window("put single pixel on screen",resolution);

//add pixel in the framebuffer
ids::gout << ids::position{0,0}
          << ids::rgb{0,0,255};

//put pixels on the screen
ids::gout.flush();

//show pixels for 10 seconds
ids::gout.delay(10s);

//close window
ids::gout.close();
