##' QGIS Algorithm provided by GDAL PCT to RGB (gdal:pcttorgb). ---------------- Arguments ---------------- INPUT: Input layer Argument type: raster Acceptable values: - Path to a raster layer BAND: Band number Default value: 1 Argument type: band Acceptable values: - Integer value representing an existing raster band number RGBA: Generate a RGBA file Default value: false Argument type: boolean Acceptable values: - 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 OUTPUT: PCT to RGB Argument type: rasterDestination Acceptable values: - Path for new raster layer

##' @title QGIS algorithm - PCT to RGB
##'
##' @param INPUT `raster` - Input layer. Path to a raster layer.
##' @param BAND `band` - Band number. Integer value representing an existing raster band number.
##' @param RGBA `boolean` - Generate a RGBA file. 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 OUTPUT `rasterDestination` - PCT to RGB. Path for new raster layer.
##' @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`.
