41、Halcon 报错：Index out of range

创建一个空的Region区域时，假若用的是GenEmptyObj，则用AreaCenter算面积时会报错Index out of range，解决办法：

把GenEmptyObj用专门创建Region的算子GenEmptyRegion

 

Dim Reg As HObject = Nothing

HOperatorSet.GenEmptyObj(Reg)

'HOperatorSet.GenEmptyRegion(Reg)

Dim Area1 As Double

Dim X1 As Double

Dim Y1 As Double

HOperatorSet.AreaCenter(Reg, Area1, Y1, X1)
