QGIS algorithm Near black

Description

QGIS Algorithm provided by GDAL Near black (gdal:nearblack)

Usage

gdal_nearblack(
  INPUT = qgisprocess::qgis_default_value(),
  NEAR = qgisprocess::qgis_default_value(),
  WHITE = qgisprocess::qgis_default_value(),
  OPTIONS = qgisprocess::qgis_default_value(),
  EXTRA = qgisprocess::qgis_default_value(),
  OUTPUT = qgisprocess::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT	raster - Input layer. Path to a raster layer.
NEAR	number - How far from black (white). A numeric value.
WHITE	boolean - Search for nearly white pixels instead of nearly black. 1 for true/yes. 0 for false/no.
OPTIONS	string - Additional creation options. String value.
EXTRA	string - Additional command-line parameters. String value.
OUTPUT	rasterDestination - Nearblack. Path for new raster 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.
