Thread: ::please help with recursion::

I know there are a lot of people with enough experience to help figure out how to debug the last problem with my program.
the problem is when you enter the starting coordinates as shown it can't fill in the whole "image" leaving out a small portion. Does anyone have any suggestions on how to get this program to function with any starting point without leaving out anything?
Also this was one of my first attempts at writing a recursive program so any advice would be appreciated.

code posted below:

Code:

#include <iostream>

//function: to simulate the paint bucket function to fill in an area of an "image"
//          specifically using recursion.

//written by: justin mortensen
//date: 08/15/05

using namespace std;
const int rows = 10;
const int col = 15;

//example "image" for testing

char image[rows][col]= {
     {'.','.','.','.','.','X','X','.','.','.','.','.','.','.','.'}, //0
     {'.','.','.','.','X','.','.','X','X','.','.','.','.','.','.'}, //1
     {'.','.','.','.','X','.','.','.','.','X','X','X','X','.','.'}, //2
     {'.','.','.','X','.','.','.','.','.','.','.','.','X','X','X'}, //3
     {'.','.','X','.','.','.','.','.','.','.','.','.','.','.','.'}, //4
     {'.','.','.','X','.','.','.','.','.','.','.','.','X','X','.'}, //5
     {'.','.','.','X','.','.','X','X','X','.','.','.','X','.','X'}, //6
     {'.','.','.','X','.','.','X','.','.','X','.','X','.','.','.'}, //7
     {'.','.','.','X','X','X','X','.','.','.','X','.','.','.','.'}, //8
     {'.','.','.','.','.','.','.','.','.','.','.','.','.','.','.'}  //9
};

// function prototypes
void printImage();
void AreaFill(int x, int y);
void AreaFill_helperLD(int x, int y); //Left and down
void AreaFill_helperRD(int x, int y); //Righ and down
void AreaFill_helperUL(int x, int y); //Up and left
void AreaFill_helperUR(int x, int y); //Up and right


int main () 
{
 printImage();
 cout << endl;
 AreaFill(6,9); //putting these coordinates at the start doesn't fill
 printImage();  //        in the whole "imag"

 cin.get();
 return 0;
}
