Arguments

GRID

raster - Grid. Path to a raster layer.

MATCHED

rasterDestination - Adjusted Grid. Path for new raster layer.

REFERENCE

raster - Reference Grid. Path to a raster layer.

METHOD

enum of ("(0) standard deviation", "(1) histogram") - Method. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

NCLASSES

number - Histogramm Classes. 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.

MAXSAMPLES

number - Maximum Sample 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.

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.
