Arguments

red	raster - Name of red channel. Path to a raster layer.
green	raster - Name of green channel. Path to a raster layer.
blue	raster - Name of blue channel. Path to a raster layer.
pan	raster - Name of raster map to be used for high resolution panchromatic channel. Path to a raster layer.
method	enum of ⁠("brovey", "ihs", "pca")⁠ - Method. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
.l	boolean - Rebalance blue channel for LANDSAT. 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. Original algorithm parameter name: -l.
.s	boolean - Process bands serially (default: run in parallel). 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. Original algorithm parameter name: -s.
redoutput	rasterDestination - Enhanced Red. Path for new raster layer.
greenoutput	rasterDestination - Enhanced Green. Path for new raster layer.
blueoutput	rasterDestination - Enhanced Blue. Path for new raster layer.
GRASS_REGION_PARAMETER	extent - GRASS GIS region 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..
GRASS_REGION_CELLSIZE_PARAMETER	number - GRASS GIS region cellsize (leave 0 for default). 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.
GRASS_RASTER_FORMAT_OPT	string - Output Rasters format options (createopt). 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.
GRASS_RASTER_FORMAT_META	string - Output Rasters format metadata options (metaopt). 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.
...	further parameters passed to qgisprocess::qgis_run_algorithm()
.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.
.quiet	logical specifying if parameter .quiet for qgisprocess::qgis_run_algorithm() Default value is TRUE.
.messages	logical specifying if messages from qgisprocess::qgis_run_algorithm() should be printed (TRUE) or not (FALSE). Default value is FALSE.
