The graphics library provides a set of portable drawing primitives. The two components are separated by a space. Either can be omitted, or both. This library is available only under the toplevel application ocamlwin.exe . The screen coordinates are interpreted as shown in the figure below.
Drawing is clipped to the screen.
The graphics window is cleared. The string argument is used to pass optional information on the desired graphics mode, the graphics window size, and so on. Its interpretation is implementation-dependent. If the empty string is given, a sensible default is selected. Delete the graphics window or switch the screen back to text mode.
