qgis_arrayoffsetlines: QGIS algorithm - Array of offset (parallel) lines

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

QGIS algorithm - Array of offset (parallel) lines

Description

QGIS Algorithm provided by QGIS (native c++) Array of offset (parallel) lines (native:arrayoffsetlines). Creates multiple offset copies of lines from a layer. This algorithm creates copies of line features in a layer, by creating multiple offset versions of each feature. Each copy is offset by a preset distance. —————- Notes —————- - This algorithm drops existing primary keys or FID values and regenerates them in output layers.

Usage

qgis_arrayoffsetlines(
  INPUT = qgisprocess:::qgis_default_value(),
  COUNT = qgisprocess:::qgis_default_value(),
  OFFSET = qgisprocess:::qgis_default_value(),
  SEGMENTS = qgisprocess:::qgis_default_value(),
  JOIN_STYLE = qgisprocess:::qgis_default_value(),
  MITER_LIMIT = 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.
COUNT	number - Number of features to create. 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.
OFFSET	distance - Offset step distance. 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.
SEGMENTS	number - Segments. 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.
JOIN_STYLE	enum of ⁠("Round", "Miter", "Bevel")⁠ - Join style. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
MITER_LIMIT	number - Miter limit. 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.
OUTPUT	sink - Offset lines. 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.
