ArcGlobe组件开发之动画4——加载保存动画

前面的几篇博文提高了3D符号化以及根据路径创建动画方面的内容，先来看下效果图：

那么创建的动画应该怎么保存呢？通过查找帮助文档以及OMD，可以知道Globe实现了IBasicScene接口和IBasicScene2接口，通过其LoadAnimation和SaveAnimation方法就可以加载和保存动画文件。如下图：

代码如下：

 //加载动画文件 .aga
        private void button_loadAnimation_Click (object sender,EventArgs e)
        {
            try
            {
                OpenFileDialog openDlgAnimation = new OpenFileDialog();
                openDlgAnimation.Title = "加载动画文件(.aga)";
                openDlgAnimation.Filter = "动画文件(*.aga)|*.aga";
                string strAnimationName = "";
                DialogResult Dr = openDlgAnimation.ShowDialog();
                if (Dr==DialogResult.OK)
                {
                    strAnimationName = openDlgAnimation.FileName;
                    IGlobe globe = m_globeControl.Globe;
                    IBasicScene basicscene = globe as IBasicScene;
                    basicscene.LoadAnimation(strAnimationName);
                }
            }
            catch (System.Exception ex)
            {
            	MyMessagebox pMyMessagebox=new MyMessagebox(ex.Message);
                pMyMessagebox.Show();
            }
           
        }
        //保存动画文件
        private void button_SaveAnimation_Click (object sender,EventArgs e)
        {
            IGlobe globe = m_globeControl.Globe;
            int tracksCount = (globe as IAGAnimationTracks).AGTracks.Count;
            if (tracksCount>0)
            {
                IBasicScene2 basicscene = globe as IBasicScene2;
                OpenFileDialog openSaveAnimationDlg = new OpenFileDialog();
                openSaveAnimationDlg.Title = "选择动画存放路径";
                openSaveAnimationDlg.Filter = "动画文件(*.aga)|*.aga";
                openSaveAnimationDlg.FileName = "输电线路动画.aga";
                DialogResult DR = openSaveAnimationDlg.ShowDialog();
                if (DR==DialogResult.OK)
                {
                    basicscene.SaveAnimation(openSaveAnimationDlg.FileName);
                } 
                else
                {
                    MyMessagebox pMymessagebox = new MyMessagebox("动画未保存！");
                    pMymessagebox.Show();
                }

            } 
            else
            {
                MyMessagebox mymessagebox = new MyMessagebox("当前视图不包含动画文件！");
                mymessagebox.Show();
            }

   

        }
