##' @param TDIRECTION `number` - Maximum 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 TNEIGHBOUR `number` - Minimum Neighbours. 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 ALIGNMENT `enum`  of `("(0) between cells", "(1) on cell")` - Alignment. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
##' @param NEIGHBOUR `enum`  of `("(0) Rooke's case", "(1) Queen's case")` - Edge Connectivity. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
##' @param FEATURES `multilayer` - Features. .
##' @param EDGE_CELLS `rasterDestination` - Edges. Path for new raster layer.
##' @param OUTPUT_ADD `enum`  of `("(0) none", "(1) gradients", "(2) edge cells")` - Additional Output. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

##' @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`.
