If not specified, or if an error occurs opening the log file, the default action is to output messages to standard output. The output dimensions are determined by the input. The return value is an integer defining the error status. In addition, to return mW rather than W, an additional scaling of 1000 is applied. All calculations are done in double precision.
Calculation is done in double precision.
See radiance output description for allowed dimensionality. If not specified, or if an error occurs opening the log file, the default action is to output messages to standard output. The output dimensions are determined by the input. See chart above. The return value is an integer defingin the error status.
