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

QGIS algorithm - Threshold raster buffer

Description

QGIS Algorithm provided by SAGA Next Gen Threshold raster buffer (sagang:thresholdrasterbuffer). —————- Arguments —————- FEATURES: Features Grid Argument type: raster Acceptable values: - Path to a raster layer VALUE: Value Grid Argument type: raster Acceptable values: - Path to a raster layer THRESHOLDGRID: Threshold Grid (optional) Argument type: raster Acceptable values: - Path to a raster layer BUFFER: Buffer Grid Argument type: rasterDestination Acceptable values: - Path for new raster layer THRESHOLD: Threshold Default value: 0 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 THRESHOLDTYPE: Threshold Type Default value: 0 Argument type: enum Available values: - 0: (0) Absolute - 1: (1) Relative from cell value Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3'

Usage

sagang_thresholdrasterbuffer(
  FEATURES = qgisprocess:::qgis_default_value(),
  VALUE = qgisprocess:::qgis_default_value(),
  THRESHOLDGRID = qgisprocess:::qgis_default_value(),
  BUFFER = qgisprocess:::qgis_default_value(),
  THRESHOLD = qgisprocess:::qgis_default_value(),
  THRESHOLDTYPE = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

FEATURES	raster - Features Grid. Path to a raster layer.
VALUE	raster - Value Grid. Path to a raster layer.
THRESHOLDGRID	raster - Threshold Grid. Path to a raster layer.
BUFFER	rasterDestination - Buffer Grid. Path for new raster 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.
THRESHOLDTYPE	enum of ⁠("(0) Absolute", "(1) Relative from cell value")⁠ - Threshold Type. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
...	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.
