QGIS algorithm - Multi-ring buffer (constant distance) — qgis

QGIS Algorithm provided by QGIS (native c++) Multi-ring buffer (constant distance) (native:multiringconstantbuffer). Computes multi-ring ('donuts') buffer using a fixed or dynamic distance and number of rings. This algorithm computes multi-ring ('donuts') buffer for the features in an input layer, using a fixed or dynamic distance and number of rings. —————- Notes —————- - This algorithm drops existing primary keys or FID values and regenerates them in output layers.

  INPUT = qgisprocess:::qgis_default_value(),

)

Arguments

INPUT: source - Input layer. Path to a vector layer.
RINGS: number - Number of rings. 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.
DISTANCE: distance - Distance between rings. 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 - Multi-ring buffer (constant distance). 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.
