QGIS Algorithm provided by SAGA Next Gen Convex hull (sagang:convexhull). ---------------- Arguments ---------------- SHAPES: Points Argument type: source Acceptable values: - Path to a vector layer HULLS: Convex Hull Argument type: vectorDestination Acceptable values: - Path for new vector layer BOXES: Minimum Bounding Box Argument type: vectorDestination Acceptable values: - Path for new vector layer POLYPOINTS: Hull Construction Default value: 1 Argument type: enum Available values: - 0: (0) one hull for all shapes - 1: (1) one hull per shape - 2: (2) one hull per shape part Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3' POLYGONCVX: Polygon Convexity Default value: false Argument type: boolean Acceptable values: - 1 for true/yes - 0 for false/no - 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

)source - Points. Path to a vector layer.
vectorDestination - Convex Hull. Path for new vector layer.
vectorDestination - Minimum Bounding Box. Path for new vector layer.
enum of ("(0) one hull for all shapes", "(1) one hull per shape", "(2) one hull per shape part") - Hull Construction. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
boolean - Polygon Convexity. 1 for true/yes. 0 for false/no. 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.
