Question

如题

Answer 1

            //纵向连接
            Bitmap bmp1 = new Bitmap(@"e:\1.JPG");
            Bitmap bmp2 = new Bitmap(@"e:\1.JPG");
            Bitmap bmp = new Bitmap(bmp1.Width, bmp1.Height + bmp2.Height);
            Graphics g = Graphics.FromImage(bmp);
            g.DrawImage(bmp1, 0, 0);
            g.DrawImage(bmp2, 0, bmp1.Height);
            bmp.Save(@"e:\2.JPG");
            bmp2.Dispose();
            bmp1.Dispose();
            bmp.Dispose();

Answer 2

System.Drawing.Image img1 = System.Drawing.Image.FromFile(@"d:\2.png");
        System.Drawing.Image img2 = System.Drawing.Image.FromFile(@"d:\5.png");        Bitmap img = new Bitmap(100, 400);        Graphics g = Graphics.FromImage(img);
        g.DrawImage(img1, 0, 0, 100, 200);
        g.DrawImage(img2, 0, 201, 100, 200);        img.Save(@"D:\aaaa.gif", System.Drawing.Imaging.ImageFormat.Jpeg);
        img1.Dispose();
        img2.Dispose();
        g.Dispose();
        img.Dispose();基本原理就是这样
