##' @param INPUT `multilayer` - Grids. .
##' @param OUTPUT `rasterDestination` - Resampled Grids. Path for new raster layer.
##' @param KEEP_TYPE `boolean` - Preserve Data Type. 1 for true/yes. 0 for false/no. 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 SCALE_UP `enum`  of `("(0) Nearest Neighbour", "(1) Bilinear Interpolation", "(2) Bicubic Spline Interpolation", "(3) B-Spline Interpolation", "(4) Mean Value", "(5) Mean Value (cell area weighted)", "(6) Minimum Value", "(7) Maximum Value", "(8) Majority")` - Upscaling Method. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
##' @param SCALE_DOWN `enum`  of `("(0) Nearest Neighbour", "(1) Bilinear Interpolation", "(2) Bicubic Spline Interpolation", "(3) B-Spline Interpolation")` - Downscaling Method. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
##' @param TARGET_USER_XMIN_TARGET_USER_XMAX_TARGET_USER_YMIN_TARGET_USER_YMAX `extent` - Output extent. A comma delimited string of x min, x max, y min, y max. E.g. '4,10,101,105'. Path to a layer. The extent of the layer is used.. Original algorithm parameter name: TARGET_USER_XMIN TARGET_USER_XMAX TARGET_USER_YMIN TARGET_USER_YMAX.
##' @param TARGET_USER_SIZE `number` - Cellsize. 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`.
