建立注記圖層要素

建立完文本注記TextElement後，可以選擇以螢幕注記的形式加到螢幕上，也可以通過下面的方式轉為注記圖層要素：

IFeatureClass annocls = 擷取注記圖層

                    IDataset pDataset = annocls as IDataset;

                    ITransactions pTransactions = pDataset.Workspace as ITransactions;

                    pTransactions.StartTransaction();

                    IFDOGraphicsLayerFactory pFDOGLFactory = new FDOGraphicsLayerFactoryClass();

                    ILayer tmpLayer = pFDOGLFactory.OpenGraphicsLayer(pDataset.Workspace as IFeatureWorkspace, annocls.FeatureDataset, pDataset.Name);

                    IFDOGraphicsLayer pFDOGLayer = tmpLayer as IFDOGraphicsLayer;

                    IElementCollection pElementColl = new ElementCollectionClass();

                    pFDOGLayer.BeginAddElements();

            ////每新增100個送出下，最後再送出下。防止過多轉換失敗

            if ((pElementColl != null) && (pElementColl.Count == 100))

            {

                pFDOGLayer.DoAddElements(pElementColl, 0);

                pFDOGLayer.EndAddElements();

                pElementColl.Clear();

                pTransactions.CommitTransaction();

 

                pTransactions.StartTransaction();

                pFDOGLayer.BeginAddElements();

            }

 

                    if (pElementColl.Count > 0)

                        pFDOGLayer.DoAddElements(pElementColl, 0);

                    pFDOGLayer.EndAddElements();

                    pElementColl.Clear();

                    pTransactions.CommitTransaction();
