QGIS algorithm - Raster layer unique values report — qgis

QGIS Algorithm provided by QGIS (native c++) Raster layer unique values report (native:rasterlayeruniquevaluesreport). Returns the count and area of each unique value in a given raster layer. This algorithm returns the count and area of each unique value in a given raster layer. The area calculation is done in the area unit of the layer's CRS.

qgis_rasterlayeruniquevaluesreport(
  INPUT = qgisprocess:::qgis_default_value(),
  BAND = qgisprocess:::qgis_default_value(),
  OUTPUT_HTML_FILE = qgisprocess:::qgis_default_value(),
  OUTPUT_TABLE = 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.
BAND: band - Band number. Integer value representing an existing raster band number.
OUTPUT_HTML_FILE: fileDestination - Unique values report. Path for new file.
OUTPUT_TABLE: sink - Unique values table. Path for new vector 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.
