Abstract

A method is described for selectively stretching and rotating a master subpicture to produce a large class of images in a computer graphics system. A subpicture is a collection of lines, circles, arcs, dimensions, etc., which can be added to a drawing as a group. Any image created on the graphics system can be used as the master for a subpicture. At the time it is filed, the designer can indicate which elements of the subpicture, if any, are to be variable. These variable declarations are filed as part of the subpicture and are referenced when an instance is requested.
