raster
- Name for input raster map (red). Path to a raster layer.
raster
- Name for input raster map (green). Path to a raster layer.
raster
- Name for input raster map (blue). Path to a raster layer.
rasterDestination
- Hue. Path for new raster layer.
rasterDestination
- Intensity. Path for new raster layer.
rasterDestination
- Saturation. Path for new raster layer.
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..
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.
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.
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()
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
.
logical specifying if parameter .quiet
for qgisprocess::qgis_run_algorithm()
Default value is TRUE
.
logical specifying if messages from qgisprocess::qgis_run_algorithm()
should be printed (TRUE
) or not (FALSE
). Default value is FALSE
.
