##' @param GRIDS `multilayer` - Original Channels. .
##' @param PAN `raster` - Panchromatic Channel. Path to a raster layer.
##' @param SHARPEN `rasterDestination` - Sharpened Channels. Path for new raster layer.
##' @param METHOD `enum` of `("(0) correlation matrix", "(1) variance-covariance matrix", "(2) sums-of-squares-and-cross-products matrix")` - Method. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
##' @param RESAMPLING `enum` of `("(0) nearest neighbour", "(1) bilinear", "(2) cubic convolution")` - Resampling. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
##' @param PAN_MATCH `enum` of `("(0) normalized", "(1) standardized")` - Panchromatic Channel Matching. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
##' @param OVERWRITE `boolean` - Overwrite. 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 ... 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`.
