QGIS algorithm - Sieve classes

Description

QGIS Algorithm provided by SAGA Next Gen Sieve classes (sagang:sieveclasses). —————- Arguments —————- INPUT: Classes Argument type: raster Acceptable values: - Path to a raster layer OUTPUT: Sieved Classes Argument type: rasterDestination Acceptable values: - Path for new raster layer MODE: Neighbourhood Default value: 0 Argument type: enum Available values: - 0: (0) Neumann - 1: (1) Moore Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3' THRESHOLD: Minimum Threshold Default value: 4 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 ALL: Class Selection Default value: 1 Argument type: enum Available values: - 0: (0) single class - 1: (1) all classes Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3' CLASS: Class Identifier Default value: 1 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_sieveclasses(
  INPUT = qgisprocess:::qgis_default_value(),
  OUTPUT = qgisprocess:::qgis_default_value(),
  MODE = qgisprocess:::qgis_default_value(),
  THRESHOLD = qgisprocess:::qgis_default_value(),
  ALL = qgisprocess:::qgis_default_value(),
  CLASS = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT

raster - Classes. Path to a raster layer.

OUTPUT

rasterDestination - Sieved Classes. Path for new raster layer.

MODE

enum of ⁠("(0) Neumann", "(1) Moore")⁠ - Neighbourhood. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

THRESHOLD

number - Minimum 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.

ALL

enum of ⁠("(0) single class", "(1) all classes")⁠ - Class Selection. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

CLASS

number - Class Identifier. 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.
