Problem with a very simple code

Hello,
I'm a very newbie with Processing and I have a problem that I don't understand.

I will write a simple program with a specified background and a Polygon positioned in the correct coordinates. This Polygon have a dimension at start and in five steps must redimensioned (zoom out).

The problem is that the drawPolygon() method called by draw() method, draw everything he found without consider the i variable. So i can't simulate a zoom out (i take the way where i draw 5 different polygon, when the first is the biggest).

How can I resolve this problem?

I'm sorry for the stupid question and probably a poor English.

If you have more advice, do not hesitate.

Thank you.

Good Evening

My code is:
2. PImage bg;
3. int startTime;
4. int totalTime=5000;
5. int i=1;
7. public void setup() {
8. size(900, 557);
9. bg = loadImage("MyImage");
10. }
12. public void draw() {
13. background(bg);
14. strokeWeight(4);
15. stroke(1);
16. noFill();
17. System.out.println("i -> " + i);
18. if ((millis()-startTime) > totalTime) {
19. startTime = millis();
20. drawPolygon(i);
21. i++;
22. if(i==6)
23. i=1;
24. }
25. }
27. private void drawPolygon(int i) {
28. switch(i) {
29. case 1:
30. beginShape();
31. ..............................
32. endShape();
33. case 2:
34. beginShape();
35. ..................
36. endShape();
37. case 3:
38. beginShape();
39. ........
40. case 4:
41. beginShape();
42. case 4:
43. beginShape();
44. ......
45. endShape();
46. case 5:
47. beginShape();
48. .............
49. endShape();
50. }
