你刚刚给出的代码出现报错，D:/桌面/Red Panda Dev C++/RedPanda-CPP/projects/五子棋/main.cpp 0 -1 In function 'void drawboard()': D:/桌面/Red Panda Dev C++/RedPanda-CPP/projects/五子棋/main.cpp 78 9 [错误] 'delimage' was not declared in this scope; did you mean 'getimage'?

很抱歉，我犯了一个错误，delimage函数应该改为DeleteObject函数，这是Windows API中释放图像资源的函数。请将代码中的delimage(&bgimg)改为DeleteObject(bgimg.getHBITMAP())，然后重新编译运行程序。

修改后的代码如下：

void drawboard() {
    COLORREF bg = RGB(255 * .9, 255 * .8, 255 * .5);
    IMAGE bgimg;
    loadimage(&bgimg, _T("C:\\bg.jpg"));  // 加载背景图片
    setbkmode(TRANSPARENT);
    setfillcolor(TRANSPARENT);
    setlinecolor(bg);
    fillrectangle(0, 0, 900, 800);  // 绘制透明矩形
    putimage(0, 0, &bgimg);  // 绘制背景图片
    setlinecolor(BLACK);
    setlinestyle(PS_SOLID, 2);
    rectangle(50 + 700, 50, 150 + 700, 100);
    setbkmode(TRANSPARENT);
    settextcolor(BLACK);
    settextstyle(30, 0, _T("Consolas"));
    outtextxy(765, 60, "reset");
    rectangle(750, 150, 850, 200);
    outtextxy(770, 160, "save");
    rectangle(750, 250, 850, 300);
    outtextxy(770, 260, "read");
    for_(i, 0, 14) {
        line(X0, Y0 + i * step, X0 + step * 14, Y0 + i * step);
        line(X0 + i * step, Y0, X0 + i * step, Y0 + step * 14 );
    }
    DeleteObject(bgimg.getHBITMAP());  // 释放图片资源
}
