#### 17.11.1 OS/2 Graphics Type

OS/2 graphics devices are created by specifying the symbol `os/2` as the graphics-device-type argument to `make-graphics-device`. The OS/2 graphics device type is implemented as a top-level window and supports color drawing in addition to the standard Scheme graphics operations.

Graphics devices are opened as follows:

         (make-graphics-device 'os/2 #!optional width height)

where width and height specify the size, in pixels, of the drawing area in the graphics window (i.e. excluding the frame).
