Arguments

DIR: raster - Direction. Path to a raster layer.
LEN: raster - Length. Path to a raster layer.
DX: rasterDestination - X Component. Path for new raster layer.
DY: rasterDestination - Y Component. Path for new raster layer.
UNITS: enum of ("(0) radians", "(1) degree") - Polar Angle Units. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
SYSTEM: enum of ("(0) mathematical", "(1) geographical", "(2) user defined") - Polar Coordinate System. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
SYSTEM_ZERO: number - User defined Zero Direction. 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.
SYSTEM_ORIENT: enum of ("(0) clockwise", "(1) counterclockwise") - User defined Orientation. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
...: 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.
