C#图像处理:截图程序(包含鼠标)

截图后在picbox中显示,用定时器定时每毫秒截图一次,在picbox上显示就有动画效果.代码:

        [DllImport("user32.dll")]
        static extern bool GetCursorInfo(out CURSORINFO pci);
 
        private const Int32 CURSOR_SHOWING = 0x00000001;
         [StructLayout(LayoutKind.Sequential)]
        struct POINT
        {
            public Int32 x;
            public Int32 y;
        }
 
        [StructLayout(LayoutKind.Sequential)]
        struct CURSORINFO
        {
            public Int32 cbSize;
            public Int32 flags;
            public IntPtr hCursor;
            public POINT ptScreenPos;
        }
 
        private void timer1_Tick(object sender, EventArgs e)
        {
            Image myimage = new Bitmap(Screen.PrimaryScreen.WorkingArea.Width, Screen.PrimaryScreen.WorkingArea.Height);
            Graphics g = Graphics.FromImage(myimage);
            g.CopyFromScreen(new Point(, ), new Point(, ), new Size(Screen.PrimaryScreen.WorkingArea.Width, Screen.PrimaryScreen.WorkingArea.Height));
            CURSORINFO pci;
            pci.cbSize = Marshal.SizeOf(typeof(CURSORINFO));
            GetCursorInfo(out pci);
            System.Windows.Forms.Cursor cur = new System.Windows.Forms.Cursor(pci.hCursor);
            cur.Draw(g, new Rectangle(pci.ptScreenPos.x - , pci.ptScreenPos.y - , cur.Size.Width, cur.Size.Height));
            pictureBox1.Image = myimage;
        }

先截屏后，然后找到鼠标的位置，后将鼠标画上去

CURSORINFO pci;
            pci.cbSize = Marshal.SizeOf(typeof(CURSORINFO));
            GetCursorInfo(out pci);
            System.Windows.Forms.Cursor cur = new System.Windows.Forms.Cursor(pci.hCursor);
            cur.Draw(g, new Rectangle(pci.ptScreenPos.x - , pci.ptScreenPos.y - , cur.Size.Width, cur.Size.Height));

以上代码就是画鼠标的代码
