QGIS Algorithm provided by QGIS (native c++) Offset lines (native:offsetline). Offsets lines by a specified distance. This algorithm offsets lines by a specified distance. Positive distances will offset lines to the left, and negative distances will offset to the right of lines. The segments parameter controls the number of line segments to use to approximate a quarter circle when creating rounded offsets. The join style parameter specifies whether round, miter or beveled joins should be used when offsetting corners in a line. The miter limit parameter is only applicable for miter join styles, and controls the maximum distance from the offset curve to use when creating a mitered join.

)source - Input layer. Path to a vector layer.
distance - 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.
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.
enum of ("Round", "Miter", "Bevel") - Join style. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
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.
sink - Offset. Path for new vector layer.
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.
