hello,

problem is when the value is too big for the screen.
This show all red-values.

Greetings, Chrisir   

1. size(640, 760);
2. PImage img = loadImage("sun.jpg");
3. image(img, 0, 0);
4. double[]r = new double[256];
5. double[]g = new double[256];
6. double[]b = new double[256];
7. for (int i=0; i<256;i++) {
8.   r[i]=0;
9.   g[i]=0;
10.   b[i]=0;
11. }
12. for (int i=0; i<img.width; i++) {
13.   for (int j=1; j<img.height; j++) {
14.     color c = img.get(i, j);
15.     r[int(red(c))]++;
16.     g[int(green(c))]++;
17.     b[int(blue(c))]++;
18.   }
19. }
20. println("done step 1");
21. println(r );
22. for (int i=0; i<r.length; i++) {
23.   stroke( (float)(r[i]), 0, 0);
24.   line (i, height, i, (float)(height-(r[i])));
25. }
26. //
