7) What is the essential purpose of composite transformation? Describe with suitable example.
8) Briefly describe Halftone approximation with its application
9) Explain C0, C1 and C2 continuity. How it differ from G0, G1 and G2 continuity. Cubic Bezier curve segment is explained by the control points P0 (1, 3), P1 (2, 8), P2 (12,9) and P3 (10, b). Another curve segment is explained by Q0 (a, 8), Q1 (9, c), Q2 (15, d) and Q3 (18, 5). Find out the value of a, b, c and d if there are C0, C1 and C2 continuity between two curve segments.
