函数：c++

void readScaleAndOffset(const char* FileName,const char* VarName)
{NcFile dataFile(FileName, NcFile::read);NcVar Varf = dataFile.getVar(VarName);//查看维度cout << "XSizef" << Varf.getDim(0).getSize() << endl;cout << "YSizef" << Varf.getDim(1).getSize() << endl;cout << "ZSizef" << Varf.getDim(2).getSize() << endl;cout << "WSizef" << Varf.getDim(3).getSize() << endl;//查看压缩值NcVarAtt AttT = Varf.getAtt("scale_factor");NcType TypeT = AttT.getType();int TypeId = TypeT.getId();  //float,长度是1float fScale = 0.0f;AttT.getValues(&fScale);AttT = Varf.getAtt("add_offset");float fOffset = 0.0f;AttT.getValues(&fOffset);cout << "scale_factor" << fScale << endl;cout << "add_offset" << fOffset << endl;
}

结果：

XSizef1
YSizef30
ZSizef501
WSizef751
scale_factor0.00189809
add_offset-7.62598
