Description

Returns the minimum value for specified field and band in MRR. If field and band are not specified, it considers the default field and band that is used for MRR rendering. If the MRR contains only the continuous field, the return type is double. If the MRR contains fields other than the continuous one, the return type is a string. This function supports all field and band types in multi-field multi-band MRR.
