In the processing book there is a example of a two dimensional array,
Only in the peace of code it get's declared, created and assigned in 1 line:

int[][] points = { {50,18}, {61, 37}, {83, 43}};

I'm wondering if it's possible to have something like this:

int[][] points; //declare
points = new int[img.width][img.height]; //create

And now my problem how can assign multiple values to that array?
points[4][12] = {255, 180, 100}; //doesnt work like some other things I tried

I want to store the rgb values that's why.
so [4][12] = the x and y coardinate and then I want to assign the rgb.
That's why I wanted [4][12] = 255, 180, 100

So maybe I must make a imageColorRed, imageColorGreen and imageColorBlue array.

Code:

PImage img;

color[][] imageColors;

void setup(){
  size(50, 100);
  img = loadImage("D:/_PhiLhoSoft/Processing/earth.png");
  noLoop();
  imageColors = new color[img.width][img.height];
  for (int y = 0; y < img.height; y++) {
    for (int x = 0; x < img.width; x++) {
	imageColors[x][y] = img.get(x, y);
    }
  }
  println(imageColors);
  DumpColors();
} 

void DumpColors()
{
  for (int y = 0; y < img.height; y++) {
    for (int x = 0; x < img.width; x++) {
	println("x=" + x + " y=" + y + " : " + hex(imageColors[x][y]));
    }
  }
}
