sagang_simplefilterrestrictedtopolygons: QGIS algorithm - Simple filter (restricted to polygons)

In JanCaha/r_package_qgis: An extension of package "qgisprocess" providing direct R functions for QGIS functions

QGIS algorithm - Simple filter (restricted to polygons)

Description

QGIS Algorithm provided by SAGA Next Gen Simple filter (restricted to polygons) (sagang:simplefilterrestrictedtopolygons). —————- Arguments —————- INPUT: Grid Argument type: raster Acceptable values: - Path to a raster layer RESULT: Filtered Grid Argument type: rasterDestination Acceptable values: - Path for new raster layer SHAPES: pPolygons Argument type: source Acceptable values: - Path to a vector layer METHOD: Filter Default value: 0 Argument type: enum Available values: - 0: (0) Smooth - 1: (1) Sharpen - 2: (2) Edge Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3' KERNEL_TYPE: Kernel Type Default value: 1 Argument type: enum Available values: - 0: (0) Square - 1: (1) Circle Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3' KERNEL_RADIUS: Radius Default value: 2 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

Usage

sagang_simplefilterrestrictedtopolygons(
  INPUT = qgisprocess:::qgis_default_value(),
  RESULT = qgisprocess:::qgis_default_value(),
  SHAPES = qgisprocess:::qgis_default_value(),
  METHOD = qgisprocess:::qgis_default_value(),
  KERNEL_TYPE = qgisprocess:::qgis_default_value(),
  KERNEL_RADIUS = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT	raster - Grid. Path to a raster layer.
RESULT	rasterDestination - Filtered Grid. Path for new raster layer.
SHAPES	source - pPolygons. Path to a vector layer.
METHOD	enum of ⁠("(0) Smooth", "(1) Sharpen", "(2) Edge")⁠ - Filter. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
KERNEL_TYPE	enum of ⁠("(0) Square", "(1) Circle")⁠ - Kernel Type. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
KERNEL_RADIUS	number - Radius. 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()
.complete_output	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.
.quiet	logical specifying if parameter .quiet for qgisprocess::qgis_run_algorithm() Default value is TRUE.
.messages	logical specifying if messages from qgisprocess::qgis_run_algorithm() should be printed (TRUE) or not (FALSE). Default value is FALSE.
