The results of a Geometric Image Analysis may be accessed using:
gia = TheSystem.Analyses.New_Analysis(ZOSAPI.Analysis.AnalysisIDM.GeometricImageAnalysis)
gia_setting = gia.GetSettings()
gia.ApplyAndWaitForCompletion()
gia_results = gia.GetResults()
gia.ApplyAndWaitForCompletion()
gia_data = zos.DoubleToNumpy(gia_results.GetDataGrid(0).Values).reshape(-1, gia_setting.NumberOfPixels)
where zos.DoubleToNumpy is tucked into the boilerplate PythonStandaloneApplication class.
