Help needed with RGB algorithm

in Programming Questions • 6 months ago

Here is the code

int w = 255;
int h =255;

PImage ax, bx, cx, dx;
int rr=255;
int gg=0;
int bb=0;

void setup() {

size(w, h);
ax=createImage(w, h, ARGB);

for (int y=0;y<h;y++) {

    for (int x=0;x<w;x++) {

      if (x==y) {

        bb=x;
      }
      rr--;
      gg++;

      ax.set(x, y, color(rr, gg, bb));
    }
    rr=255;
    gg=0;
}
image(ax, 0, 0);
}

void draw() {
color c = ax.get(mouseX, mouseY);
rr = c>>16&255;
gg = c>>8&255;
bb = c&255;
this.frame.setTitle(str(rr)+ " "+str(gg)+ " "+ str(bb));
}

I want to crate a RGB box where each corner has the highest red,green and blue i.e. 255. I have the two top corner as red and green but the blue corner still has green in it. The fourth corner I want to be 255,255,255

Can anyone help ?

Here is an image of what I have so far.
