MFC实现四连通种子填充算法的问题。
程序不知道哪出错了，最后在屏幕上只能打印种子点和其上、下、左、右五个点，无法实现填充，希望得到指点，以下是我的代码。
void CFill_fourView::OnLButtonDown(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
m_point = point;
//flag = true;
Fill_four(m_point);
CView::OnLButtonDown(nFlags, point);
}
void CFill_fourView::Fill_four(CPoint point)
{
CPoint p;
CPoint rPoint,lPoint,tPoint,bPoint;
CClientDC dc(this);
COLORREF color;
stack.Push(point);
while(stack.Pop(p))
{
dc.SetPixel(p,RGB(0,0,255));
rPoint.x = point.x+1;
rPoint.y = point.y;
lPoint.x = point.x-1;
lPoint.y = point.y;
tPoint.x = point.x;
tPoint.y = point.y-1;
bPoint.x = point.x;
bPoint.y = point.y+1;
color = dc.GetPixel(tPoint);
if(color != RGB(0,0,0) && color != RGB(0,0,255))
stack.Push(tPoint);
color = dc.GetPixel(bPoint);
if(color != RGB(0,0,0) && color != RGB(0,0,255))
stack.Push(bPoint);
color = dc.GetPixel(lPoint);
if(color != RGB(0,0,0) && color != RGB(0,0,255))
stack.Push(lPoint);
color = dc.GetPixel(rPoint);
if(color != RGB(0,0,0) && color != RGB(0,0,255))
stack.Push(rPoint);
}

[解决办法]
我记得XP自带画图用的不是这个算法。是E字打头的那个边界填充
