修正光标图像热点

        public void SetCursor(Bitmap cursor, Point hotPoint)//移动自定义光标的图象位置，使他在0 0点起作用
        {
            try {
            int hotX = hotPoint.X;
            int hotY = hotPoint.Y;
            Bitmap myNewCursor = new Bitmap(cursor.Width * 2 - hotX, cursor.Height * 2 - hotY);
            Graphics g = Graphics.FromImage(myNewCursor);
            g.DrawImage(cursor, cursor.Width - hotX, cursor.Height - hotY, cursor.Width, cursor.Height);
            theImage.Cursor = new Cursor(myNewCursor.GetHicon());
            g.Dispose();
            }
            catch(Exception ex)
            { }
        }

 

 

调用方法 

                        Cursor obj = new Cursor(curbmp.GetHicon());
                        SetCursor(curbmp, obj.HotSpot);//目前遇到的自定义光标是在中间位置
