The Polygon Group

Introduction

All of the commands in this group use the polygon buffer, a

temporary data storage area in your printer. Using the polygon

buffer is an integral part of drawing wedges, rectangles, and

other types of polygons. Some of the commands in this chapter

define and draw complete shapes while others act only on the

contents of the polygon buffer. The information in this chapter

enables you to achieve the following results in your programs:

z Draw circles, wedges, and rectangles.

z Use polygon mode for drawing polygons, subpolygons, and

circles.

The following commands are described in this chapter:
