Chapter 2 Graphics Tutorial Figure 2. 24. Printout of a Circle Made with PMRA Drawing Complex Curves PRESCRIBE also provides a second curve-drawing operator for constructing complex curves that are referred to as Bézier curve segments. The PCRP (Path, Curve to Relative Position) uses the following format. PCRP x1, y1, x2, y2, x3, y3; Figure 2. 25. Bézier Curves x1, y1 x2, y2 Current position x1, y1 x3, y3 Current position x2, y2 x3, y3 x2, y2 x1, y1 Current position x3, y3 A Bézier curve segment is one that is geometrically defined by a starting point (the cursor's current position), two control points (x1, y1 and x2, y2), and an ending point (x3, y3). Coordinates of each of these points are specified as an offset from the cursor's previous position. 2-26
