QGIS Algorithm provided by QGIS (native c++) Zonal statistics (native:zonalstatisticsfb). This algorithm calculates statistics of a raster layer for each feature of an overlapping polygon vector layer.

)source - Input layer. Path to a vector layer.
raster - Raster layer. Path to a raster layer.
band - Raster band. Integer value representing an existing raster band number.
string - Output column prefix. String value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
enum of ("Count", "Sum", "Mean", "Median", "St dev", "Minimum", "Maximum", "Range", "Minority", "Majority", "Variety", "Variance") - Statistics to calculate. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
sink - Zonal Statistics. Path for new vector layer.
further parameters passed to qgisprocess::qgis_run_algorithm()
logical specifying if complete out of qgisprocess::qgis_run_algorithm() should be used (TRUE) or first output (most likely the main) should read (FALSE). Default value is TRUE.
logical specifying if parameter .quiet for qgisprocess::qgis_run_algorithm() Default value is TRUE.
logical specifying if messages from qgisprocess::qgis_run_algorithm() should be printed (TRUE) or not (FALSE). Default value is FALSE.
