Java How do I make this flag?

int height = grid.getHt();
int width = grid.getWd();
//Paints everything Blue
for(int c=0;c<height;c++){
    for(int d=0;d<width;d++){
        grid.setColor(c,d,Color.CYAN);
    }    
}
//Paints a Yellow Line
for(int c=(height/3);c<((height*2)/3);c++){
    for(int d=0;d<width;d++){
        grid.setColor(c, d, Color.YELLOW);
    }
}
//makes the triangle
int temp;
temp = 0;
for(int d=0;d<(width-2)/4;d++){
    for(int c=0+temp;c<height-temp;c++){
        grid.setColor(c,d,Color.BLACK);
    }
    temp++;
}
//Makes that last black dot at the end of the triangle
if(height<=9){
    for(int c=(height-1)/2;;){
        for(int d=0;d<=(width-2)/4;d++){
            grid.setColor(c,d,Color.BLACK);
        }
    }
} else { 
    for(int j=0; j<=2; j++){
        int z=0;
        for(int c=0;c<(height-1)/2;c++){
            for(int d=0;d<=(width-2)/4;d++){
                grid.setColor(c-1,d,Color.BLACK);
            }
        }
    }
}

So i'm supposed to draw this flag using java grids, this is what i currently have. http://ift.tt/1ALfIxG at size 9 it looks fine, but at size 12 it is missing a black dot. How can I solve this?
