QGIS Algorithm provided by SAGA Next Gen Sieve classes (sagang:sieveclasses). ---------------- Arguments ---------------- INPUT: Classes Argument type: raster Acceptable values: - Path to a raster layer OUTPUT: Sieved Classes Argument type: rasterDestination Acceptable values: - Path for new raster layer MODE: Neighbourhood Default value: 0 Argument type: enum Available values: - 0: (0) Neumann - 1: (1) Moore Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3' THRESHOLD: Minimum Threshold Default value: 4 Argument type: number Acceptable values: - A numeric 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 ALL: Class Selection Default value: 1 Argument type: enum Available values: - 0: (0) single class - 1: (1) all classes Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3' CLASS: Class Identifier Default value: 1 Argument type: number Acceptable values: - A numeric 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

)raster - Classes. Path to a raster layer.
rasterDestination - Sieved Classes. Path for new raster layer.
enum of ("(0) Neumann", "(1) Moore") - Neighbourhood. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
number - Minimum Threshold. A numeric 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 ("(0) single class", "(1) all classes") - Class Selection. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
number - Class Identifier. A numeric 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.
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.
