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(0, 0), new Point(0, 0), 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 - 10, pci.ptScreenPos.y - 10, 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 - 10, pci.ptScreenPos.y - 10, cur.Size.Width, cur.Size.Height));
以上代码就是画鼠标的代码
