##' @title QGIS algorithm - Translate (convert format)
##'
##' @param INPUT `raster` - Input layer. Path to a raster layer.
##' @param TARGET_CRS `crs` - Override the projection for the output file. CRS as an auth ID (e.g. 'EPSG:3111'). CRS as a PROJ4 string (e.g. 'PROJ4:…'). CRS as a WKT string (e.g. 'WKT:…'). Path to a layer. The CRS of the layer is used..
##' @param NODATA `number` - Assign a specified NoData value to output bands. 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 COPY_SUBDATASETS `boolean` - Copy all subdatasets of this file to individual output files. 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 OPTIONS `string` - Additional creation options. String 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 EXTRA `string` - Additional command-line parameters. String 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 DATA_TYPE `enum`  of `("Use Input Layer Data Type", "Byte", "Int16", "UInt16", "UInt32", "Int32", "Float32", "Float64", "CInt16", "CInt32", "CFloat32", "CFloat64", "Int8")` - Output data type. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
##' @param OUTPUT `rasterDestination` - Converted. 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`.
