win32api在窗口中输出字，为什么背后总是带白色的背景

Question

就是你输了这一段背后的这一段的白色背景
代码如下：
void g_eat_p(HDC hdc, RECT rect)
{
HFONT hf;
char lost[]="你输了！";
hf = CreateFont((rect.top+rect.bottom)/10, 0, 0, 0, 400, 0, 0, 0, ANSI_CHARSET, OUT_DEFAULT_PRECIS,
CLIP_DEFAULT_PRECIS, DEFAULT_QUALITY, DEFAULT_PITCH|FF_DONTCARE, "字体");

for(int k=0; k<4; k++)
{
    if(g[k].weak==0 && g[k].life==1 && (( (g[k].x+16)/16==(p.x+16)/16 && (g[k].y+16)/16==(p.y+16)/16 ) || 
        ( (g[k].x-p.x)*(g[k].x-p.x)+(g[k].y-p.y)*(g[k].y-p.y)<=p.speed*p.speed)) )//假如鬼吃了吃豆人
    {
        SelectObject(hdc, hf);
        SetTextColor(hdc,RGB(255,0,0));
        TextOut(hdc, (rect.left+rect.right)/2, (rect.top+rect.bottom)/2, lost, strlen(lost));
        DeleteObject(hf);
        stop=1;
        break;
    }
}

}

Answer 1

SetBkMode(hdc,TRANSPARENT); //加上
TextOut(hdc, (rect.left+rect.right)/2, (rect.top+rect.bottom)/2, lost, strlen(lost));
