StackOverFlowError when trying to call recursive method

I'm developing an image editor like Paint , and I can not do the paint bucket method, the idea is like this: (example)

I have an 8x8 array and the possible values in this example are "-", "X" or "O"

   0  1  2  3  4  5  6  7
0 [-][-][-][-][-][-][-][x]
1 [-][-][-][-][-][-][x][-]
2 [-][-][-][-][-][x][-][-]
3 [-][-][-][-][x][-][-][-]
4 [-][-][-][-][x][-][-][-]
5 [-][-][x][x][-][-][-][-]
6 [-][x][-][-][-][-][-][-]
7 [x][-][-][-][-][-][-][-]

In my method I choose a field that has a "-", then it and all the fields on the sides or above or below that are "-", become "O" and this is a recursive method, example : pint (5,6);

   0  1  2  3  4  5  6  7
0 [-][-][-][-][-][-][-][x]
1 [-][-][-][-][-][-][x][o]
2 [-][-][-][-][-][x][o][o]
3 [-][-][-][-][x][o][o][o]
4 [-][-][-][-][x][o][o][o]
5 [-][-][x][x][o][o][o][o]
6 [-][x][o][o][o][o][o][o]
7 [x][o][o][o][o][o][o][o]

My code implementing in a bufferedImage instead of an array:

public static void pinta(BufferedImage buff,int x,int y,int color)
{
        int filtro=buff.getRGB(x,y);
        buff.setRGB(x,y,color);
        if(filtro!=color){
            if(buff.getRGB(x+1, y)==filtro){
                pinta(buff,x+1,y,color);
            }
            if(buff.getRGB(x-1, y)==filtro){
                pinta(buff,x-1,y,color);
            }
            if(buff.getRGB(x, y+1)==filtro){
                pinta(buff,x,y+1,color);
            }
            if(buff.getRGB(x, y-1)==filtro){
                pinta(buff,x,y-1,color);
            }
        }
    }

This code works for the example of the array because it is too small, but when I try on a large image, greater than 200px and 200px more or less, it StackOverflowError , does not have to be with the fact I have not put a condition to avoid CordenatesOffBoundException , considering that this will not happen in my example to facilitate. So how do I do this method without using resource? can someone give me an example code?
