QGIS Algorithm provided by QGIS (native c++) Tapered buffers (native:taperedbuffer). This algorithm creates tapered buffers along line geometries, using a specified start and end buffer diameter corresponding to the buffer diameter at the start and end of the linestrings.

qgis_taperedbuffer(
  INPUT = qgisprocess:::qgis_default_value(),
  START_WIDTH = qgisprocess:::qgis_default_value(),
  END_WIDTH = qgisprocess:::qgis_default_value(),
  SEGMENTS = 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.

START_WIDTH

number - Start width. 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.

END_WIDTH

number - End width. 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.

OUTPUT

sink - Buffered. 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.
