CAD注记层转到SDE Annotation Features本文会提到两种方式,不过都是要添加一个element,所以,首先给出一个创建element的函数
ITextElementPtr MakeTextElement(CString strText, double x, double y)
{
HRESULT hr;
ITextElementPtr ipTextElement(CLSID_TextElement);
hr = ipTextElement->put_ScaleText(VARIANT_TRUE);
hr = ipTextElement->put_Text(CComBSTR(strText));
IGroupSymbolElementPtr ipGroupSymEle = ipTextElement;
ipGroupSymEle->put_SymbolID(0);
IPointPtr ipPoint(CLSID_Point);
ipPoint->put_X(x);
ipPoint->put_Y(y);
IElementPtr ipElement = ipTextElement;
ipElement->put_Geometry(ipPoint);
return ipTextElement;
}
第一种办法,通过IFDOGraphicsLayer添加Elements的方式实现,实现办法如下
BOOL AddTextElementEx(CString strText, double x, double y)
{
HRESULT hr;
IFeatureWorkspacePtr ipFeatWorkspace = m_ipWorkspace;
if(ipFeatWorkspace == NULL)
return FALSE;
IFeatureClassPtr ipFeatureClass;
hr = ipFeatWorkspace->OpenFeatureClass(CComBSTR(_T("abc")),&ipFeatureClass);
IWorkspaceEditPtr ipWorkspaceEdit = m_ipWorkspace;
if(ipWorkspaceEdit==NULL)
return FALSE;
IDatasetPtr ipDataset(ipFeatureClass);
IFDOGraphicsLayerFactoryPtr ipFDOGLFactory(CLSID_FDOGraphicsLayerFactory);
IWorkspacePtr ipWs;
ipDataset->get_Workspace(&ipWs);
IFeatureWorkspacePtr ipFeatWs(ipWs);
IFeatureDatasetPtr ipFeatDataset;
ipFeatureClass->get_FeatureDataset(&ipFeatDataset);
ILayerPtr ipLayer;
BSTR bstr;
hr = ipDataset->get_Name(&bstr);
hr = ipFDOGLFactory->OpenGraphicsLayer(ipFeatWs,ipFeatDataset,bstr,&ipLayer);
if(FAILED(hr))
return FALSE;IFDOGraphicsLayerPtr ipFDOGLayer(ipLayer);
IElementCollectionPtr ipElementColl;
hr = ipElementColl.CreateInstance(CLSID_ElementCollection);
if(FAILED(hr)||ipElementColl==NULL)
return FALSE;
ITextElementPtr ipTextElement = MakeTextElement(strText,x,y);
hr = ipElementColl->Add((IElementPtr)ipTextElement,-1);
hr = ipFDOGLayer->BeginAddElements();
hr = ipFDOGLayer->DoAddElements(ipElementColl,0);
hr = ipFDOGLayer->EndAddElements();
return TRUE;
}
第二种方式,通过IAnnotationFeature来实现,实现代码如下
BOOL AddTextElement(CString strText, double x, double y)
{
HRESULT hr;
IFeatureWorkspacePtr ipFeatWorkspace = m_ipWorkspace;
if(ipFeatWorkspace == NULL)
return FALSE;
IFeatureClassPtr ipFeatureClass;
hr = ipFeatWorkspace->OpenFeatureClass(CComBSTR(_T("abc")),&ipFeatureClass);
IWorkspaceEditPtr ipWorkspaceEdit = m_ipWorkspace;
if(ipWorkspaceEdit==NULL)
return FALSE;
hr = ipWorkspaceEdit->StartEditing(TRUE);
hr = ipWorkspaceEdit->StartEditOperation();
hr = ipWorkspaceEdit->EnableUndoRedo();
IElementPtr ipElement = MakeTextElement(strText,x , y);
IAnnotationFeaturePtr ipAnnotationFeature = ipFeature;
if(ipAnnotationFeature == NULL)
return FALSE;
hr=ipAnnotationFeature->put_Annotation(ipElement);
ipWorkspaceEdit->DisableUndoRedo();
ipWorkspaceEdit->StopEditOperation();
ipWorkspaceEdit->StopEditing(TRUE);
return TRUE;
}
这两种方法,经过实际测试都可以成功,在导入的时候还需要注意一下空间参考系的问题,需要对应上,特别要注意dwg中的数据是否正确,如果注记的坐标不在参考系范围内,会出现导入失败的现象,我就是因为这个低级的错误,纠结了两天。
