QGIS algorithm - Polygon generalization

Description

QGIS Algorithm provided by SAGA Next Gen Polygon generalization (sagang:polygongeneralization). —————- Arguments —————- POLYGONS: Shapes Argument type: source Acceptable values: - Path to a vector layer GENERALIZED: Shape Indices Argument type: vectorDestination Acceptable values: - Path for new vector layer THRESHOLD: Threshold Default value: 100 Argument type: number Acceptable values: - 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

Usage

sagang_polygongeneralization(
  POLYGONS = qgisprocess:::qgis_default_value(),
  GENERALIZED = qgisprocess:::qgis_default_value(),
  THRESHOLD = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

POLYGONS

source - Shapes. Path to a vector layer.

GENERALIZED

vectorDestination - Shape Indices. Path for new vector layer.

THRESHOLD

number - Threshold. 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.

...

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.
