AG_DRIVERSDL2FB(3)

NAME
AG_DriverSDL2FB - agar SDL2 frame-buffer driver

DESCRIPTION
The Agar sdl2fb driver provides an interface to the Simple DirectMedia Layer (SDL) library version 2 (SDL2), and renders Agar GUI elements directly to the frame-buffer.

Using AG_InitVideoSDL(3) as opposed to AG_InitGraphics(3), it is possible to attach Agar to an existing SDL2 display surface.

INHERITANCE HIERARCHY
AG_Driver(3) -> AG_DriverSw(3) -> AG_DriverSDL2FB.

EXAMPLES

    AG_InitGraphics("sdl2fb(width=640:height=480)");
    AG_InitGraphics("sdl2fb(width=60%:height=80%)");
    AG_InitVideoSDL(an_existing_SDL_screen, 0);
