推荐答案

如果你忽略了长宽比：

        Image img1;
        Image img2;
        Image img3;

        Bitmap display = new Bitmap(img1.Width, (int)(img1.Height * 1.5));
        Graphics g = Graphics.FromImage(display);

        //draw img1 to upper left corner
        g.DrawImage(img1, 0, 0);

        //draw img2 under img1, left side
        g.DrawImage(img2, 0, img1.Height, img1.Width / 2.0f, img1.Height / 2.0f);

        //draw img3 under img1, right side
        g.DrawImage(img3, img1.Width / 2.0f, img1.Height, img1.Width / 2.0f, img1.Height / 2.0f);
