辅助函数
本来应该写更多的辅助函数的,将窗体响应函数里面的代码放到里面来,不过本人很懒,就这样将就了.呵呵
private void DrawRect(Graphics Painter, int Mouse_x, int Mouse_y) { int width = 0; int heigth = 0; if (Mouse_y < Rect.Y) { Rect.Y = Mouse_y; heigth = downPoint.Y - Mouse_y; } else { heigth = Mouse_y - downPoint.Y; } if (Mouse_x < Rect.X) { Rect.X = Mouse_x; width = downPoint.X - Mouse_x; } else { width = Mouse_x - downPoint.X; } Rect.Size = new Size(width, heigth); Painter.DrawRectangle(pen, Rect); } private Image DrawScreen(Image back, int Mouse_x, int Mouse_y) { Graphics Painter = Graphics.FromImage(back); DrawRect(Painter, Mouse_x, Mouse_y); return back; } private void MoveRect(Image image, Rectangle Rect) { Graphics Painter = Graphics.FromImage(image); Painter.DrawRectangle(pen, Rect.X, Rect.Y, Rect.Width, Rect.Height); DrawRects(Painter); MainPainter.DrawImage(image, 0, 0); image.Dispose(); } |
到这里,代码就算是写完了,运行
截取结果,这里截取的边界没有控制好,所以还有边界可以见到,稍微设置一下就可以了
好了,这个东东就这样搞完了，接下来要做利用钩子的了....希望能够快点完成,累呀~~~~
