Exporting Animated Gif's (glitch)

Hi guys - sorry for the total noob question :)

i've just started messing about with Processing - and i'm teaching myself about loops right now.

i wrote a very pedestrian bit of code that draws an area of points

and then assigns these points a spectrum of color and then made them change slightly with every iteration of the loop
2. import gifAnimation.*;
4. GifMaker gifExport;
5. float a = (0);
6. float b = (255);
8. float changea = 2.5;
9. float changeb = -2.5;
11. void setup(){
12. size(500,500);
13. background(0);
14. rectMode(CENTER);
15. println("gifAnimation " + Gif.version());
16. gifExport = new GifMaker(this, "export-###.gif");
17. gifExport.setRepeat(0);
18. }
20. void draw(){
21. if (keyPressed == true) {
22. gifExport.finish();
23. }else{
24. //gifExport.setDelay(1);
25. gifExport.addFrame();
26. }
28. for (int i = 50; i <=450; i+=3) {
29. for (int j = 50; j<=450; j+=3){
30. stroke(255,0,i-a);
31. point(i,j);
33. a += changea;
34. b += changeb;
36. if((a<0)||(a>255)){
37. changea *= -1;
38. }
39. if((b<0)||(b>255)){
40. changeb *= -1;
41. }
42. }
43. }
44. }
i also imported a gif exporting library - and it all works great

but the gifs come with a blank frame at the end (??) (see below)

i was wondering if there's a way to tell it to not include that blank frame :)

thank you :)
