AG_DRIVERSDLFB(3)

NAME
AG_DriverSDLFB - agar SDL1 frame-buffer driver

DESCRIPTION
The Agar sdlfb driver provides an interface to the Simple DirectMedia Layer (SDL) library version 1.2, and renders 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 SDL display surface.

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

EXAMPLES

    AG_InitGraphics("sdlfb(width=640:height=480:joy)");
    AG_InitGraphics("sdlfb(width=60%:height=80%)");
    AG_InitGraphics("sdlgl(bgColor=0/120/120)");
    AG_InitVideoSDL(an_existing_SDL_screen, 0);
