##' @param INPUT `raster` - Grid. Path to a raster layer.
##' @param MASK `raster` - Mask. Path to a raster layer.
##' @param RESULT3 `rasterDestination` - Destriped Grid. Path for new raster layer.
##' @param RESULT1 `rasterDestination` - Low-pass 1. Path for new raster layer.
##' @param RESULT2 `rasterDestination` - Low-pass 2. Path for new raster layer.
##' @param STRIPES `rasterDestination` - Stripes. Path for new raster layer.
##' @param ANG `number` - Angle. 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.
##' @param R `number` - Radius. 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.
##' @param D `number` - Stripes Distance. 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.
##' @param ... further parameters passed to `qgisprocess::qgis_run_algorithm()`
##' @param .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`.
##' @param .quiet logical specifying if parameter `.quiet` for `qgisprocess::qgis_run_algorithm()` Default value is `TRUE`.
##' @param .messages logical specifying if messages from `qgisprocess::qgis_run_algorithm()` should be printed (`TRUE`) or not (`FALSE`). Default value is `FALSE`.
