qgis_centroids: QGIS algorithm - Centroids

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

QGIS algorithm - Centroids

Description

QGIS Algorithm provided by QGIS (native c++) Centroids (native:centroids). This algorithm creates a new point layer, with points representing the centroid of the geometries in an input layer. The attributes associated to each point in the output layer are the same ones associated to the original features. —————- Notes —————- - This algorithm may drop existing primary keys or FID values and regenerate them in output layers, depending on the input parameters.

Usage

qgis_centroids(
  INPUT = qgisprocess:::qgis_default_value(),
  ALL_PARTS = qgisprocess:::qgis_default_value(),
  OUTPUT = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT	source - Input layer. Path to a vector layer.
ALL_PARTS	boolean - Create centroid for each part. 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.
OUTPUT	sink - Centroids. 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.
