QGIS algorithm - Create random raster layer (uniform distribution) — qgis

QGIS Algorithm provided by QGIS (native c++) Create random raster layer (uniform distribution) (native:createrandomuniformrasterlayer). Generates a raster layer for given extent and cell size filled with random values. By default, the values will range between the minimum and maximum value of the specified output raster type. This can be overridden by using the advanced parameters for lower and upper bound value. If the bounds have the same value or both are zero (default) the algorithm will create random values in the full value range of the chosen raster data type. Choosing bounds outside the acceptable range of the output raster type will abort the algorithm.

Arguments

EXTENT: extent - Desired extent. A comma delimited string of x min, x max, y min, y max. E.g. '4,10,101,105'. Path to a layer. The extent of the layer is used..
TARGET_CRS: crs - Target CRS. CRS as an auth ID (e.g. 'EPSG:3111'). CRS as a PROJ4 string (e.g. 'PROJ4:…'). CRS as a WKT string (e.g. 'WKT:…'). Path to a layer. The CRS of the layer is used..
PIXEL_SIZE: number - Pixel size. 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.
OUTPUT_TYPE: enum of ("Byte", "Integer16", "Unsigned Integer16", "Integer32", "Unsigned Integer32", "Float32", "Float64") - Output raster data type. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
LOWER_BOUND: number - Lower bound for random number range. 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.
UPPER_BOUND: number - Upper bound for random number range. 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.
OUTPUT: rasterDestination - Output raster. 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.
