Abstract: | A graphical output system small enough to fit on a medium range micro computer is described. The system, called Outline, allows the user to produce line drawings in an infinite two dimensional space. It also offers a picture building facility in which the relationship between different sub-pictures is specified by mathematical transformations. A basic set of picture manipulating facilities along with a set of physical drawing attributes for each device is defined. The system is embedded in a high level language for simplicity of use. |
