[求助]如何把图纸中所有的文字提取出来
刚学ObjectARX，现在想实现把当前文档中包含的所有文字提取出来，请各位前辈高人指点。 最简单的就是遍历数据库然后判断类型是否是文字了，isKindOf( AcdbText::desc() )
谢谢dll，不知道有没有这样的例子 给你一段代码吧 希望对你有启发
AcDbDatabase* pDb = acdbHostApplicationServices()->workingDatabase();
if (pDb == NULL)
{
acutPrintf("\n当前无活动的图形!");
return false;
}
AcDbBlockTable *pBlockTable;
if (pDb->getBlockTable(pBlockTable, AcDb::kForRead) != Acad::eOk)
{
acutPrintf("\n打开块表失败!");
return false;
}
AcDbBlockTableRecord *pBlockRec;
if (pBlockTable->getAt(ACDB_MODEL_SPACE, pBlockRec, AcDb::kForRead)!= Acad::eOk)
{
acutPrintf("打开模型空间失败!");
pBlockTable->close();
return false;
}
pBlockTable->close();
AcDbBlockTableRecordIterator* pIterator,*pIter;
pBlockRec->newIterator(pIterator,true,false);
pBlockRec->newIterator(pIter,true,false);
if( pIterator->done())
{
acutPrintf("\n当前图形无数据。");
pBlockRec->close();
delete pIterator;
return false;
}
AcDbEntity* pEnt;
for(; !pIterator->done(); pIterator->step(true,false))
{
if(pIterator->getEntity(pEnt, AcDb::kForRead,true)!=Acad::eOk)
continue;
if(pEnt->isKindOf(AcdbText::desc() true)
{
AcDbObjectId eId;
eId=pEnt->objectId();
ids.append(eId);
}
pEnt->close();
}
pBlockRec->close();
delete pIterator;
太感谢nogirlfriend了。
