What I am trying to get the parameters from the command line dynamically, like following, let's say my app is program.exe:

1. program.exe width=800 height=600

What am I doing it wrong with the above sketch?

1. void setup() {
2.     size(3286, 1080, OPENGL);
3.     frameRate(30);
4.     bg                  = loadImage("bg.png");
5. }
6. 
   
7. void draw() {
8.     background(bg);
9. 
   
10.     PImage noteImg      = get(2309, 138, 589, 538);
11.     String filename     = "test.png";
12.     noteImg.save(savePath("data/" + filename));
13.     noLoop();
14. }
