##' @title QGIS algorithm - Line smoothing
##'
##' @param LINES_IN `source` - Lines. Path to a vector layer.
##' @param LINES_OUT `vectorDestination` - Smoothed Lines. Path for new vector layer.
##' @param METHOD `enum` of `("(0) basic SIA model", "(1) improved SIA model", "(2) Gaussian Filtering")` - Method. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
##' @param SENSITIVITY `number` - Sensitivity. 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 ITERATIONS `number` - Iterations. 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 PRESERVATION `number` - Preservation. 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 SIGMA `number` - Sigma. 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`.
