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

QGIS algorithm Polygonize (raster to vector)

Description

QGIS Algorithm provided by GDAL Polygonize (raster to vector) (gdal:polygonize)

Usage

gdal_polygonize(
  INPUT = qgisprocess::qgis_default_value(),
  BAND = qgisprocess::qgis_default_value(),
  FIELD = qgisprocess::qgis_default_value(),
  EIGHT_CONNECTEDNESS = qgisprocess::qgis_default_value(),
  EXTRA = qgisprocess::qgis_default_value(),
  OUTPUT = qgisprocess::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT	raster - Input layer. Path to a raster layer.
BAND	band - Band number. Integer value representing an existing raster band number.
FIELD	string - Name of the field to create. String value.
EIGHT_CONNECTEDNESS	boolean - Use 8-connectedness. 1 for true/yes. 0 for false/no.
EXTRA	string - Additional command-line parameters. String value.
OUTPUT	vectorDestination - Vectorized. Path for new vector layer.
...	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.
