QGIS algorithm Build overviews (pyramids)

Description

QGIS Algorithm provided by GDAL Build overviews (pyramids) (gdal:overviews)

Usage

gdal_overviews(
  INPUT = qgisprocess::qgis_default_value(),
  CLEAN = qgisprocess::qgis_default_value(),
  LEVELS = qgisprocess::qgis_default_value(),
  RESAMPLING = qgisprocess::qgis_default_value(),
  FORMAT = qgisprocess::qgis_default_value(),
  EXTRA = 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.

CLEAN

boolean - Remove all existing overviews. 1 for true/yes. 0 for false/no.

LEVELS

string - Overview levels (e.g. 2 4 8 16). String value.

RESAMPLING

enum of ("Nearest Neighbour (default)", "Average", "Gaussian", "Cubic Convolution", "B-Spline Convolution", "Lanczos Windowed Sinc", "Average MP", "Average in Mag/Phase Space", "Mode") - Resampling method. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

FORMAT

enum of ("Internal (if possible)", "External (GTiff .ovr)", "External (ERDAS Imagine .aux)") - Overviews format. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

EXTRA

string - Additional command-line parameters. String value.

...

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.
