AG_DRIVERSDL2GL(3) Library Functions Manual AG_DRIVERSDL2GL(3) NAME AG_DriverSDL2GL -- agar SDL2 OpenGL driver DESCRIPTION The Agar sdl2gl driver provides an interface to the Simple DirectMedia Layer (SDL) library version 2, and renders GUI elements as OpenGL prim- itives and managed textures. Using AG_InitVideoSDL(3) as opposed to AG_InitGraphics(3), it is possi- ble to attach Agar to an existing SDL display surface. If the SDL sur- face has the SDL_OPENGL flag set then sdl2gl will be auto-selected by default. INHERITANCE HIERARCHY AG_Driver(3) -> AG_DriverSw(3) -> AG_DriverSDL2GL. EXAMPLES AG_InitGraphics("sdl2gl(width=640:height=480)"); AG_InitGraphics("sdl2gl(width=60%:height=80%)"); AG_InitGraphics("sdl2gl(bgColor=0/120/120)"); AG_InitGraphics("sdl2gl(out=%08d.jpg:jpegQual=100)"); AG_InitGraphics("sdl2gl(depth=64:stereo)"); AG_InitVideoSDL(an_existing_SDL_screen, 0); OPTIONS ctrl Enable game controller (gamepad) support. haptic Enable haptic (force feedback) subsystem. joy Enable joystick input device support. width Width (in pixels, in % of total desktop or "auto"). height Height (in pixels, in % of total desktop or "auto"). bgColor Solid background color (in 8-bit "R/G/B" format). !bgPopup Disable the right-click background popup menu (which includes, notably the list of active windows). clampOnResize Whenever the display is resized, clamp Agar window po- sitions and sizes to fit the new display size. debug Capture GL_DEBUG_OUTPUT errors. depth Depth (in bits per pixel or "auto"). fpsMax Limit refresh rate in frames/second (e.g., "60"). out Export video frames to JPEG or PNG. Specify a format string for output file names. Example: `%04d.jpg' will output frames to 0001.jpg, 0002.jpg, and so on. outFirst Override first frame number (default = 0). outLast Terminate after # frames have been rendered. jpegDCT (JPEG Export) DCT method ("islow", "ifast" or "float"). jpegQual (JPEG Export) Quality factor (100% = best). stereo Request a stereoscopic visual.
