Arguments

GRID

raster - Classification. Path to a raster layer.

GRID_VALUES

enum of ("(0) values are class identifiers", "(1) use look-up table") - Value Interpretation. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

GRID_LUT

source - Look-up Table. Path to a vector layer.

GRID_LUT_MIN

field - Value. The name of an existing field. ; delimited list of existing field names.

GRID_LUT_MAX

field - Value (Maximum). The name of an existing field. ; delimited list of existing field names.

GRID_LUT_NAM

field - Name. The name of an existing field. ; delimited list of existing field names.

POLYGONS

source - Polygons. Path to a vector layer.

FIELD

field - Classes. The name of an existing field. ; delimited list of existing field names.

CONFUSION

vectorDestination - Confusion Matrix. Path for new vector layer.

CLASSES

vectorDestination - Class Values. Path for new vector layer.

SUMMARY

vectorDestination - Summary. Path for new vector layer.

NO_CLASS

boolean - Unclassified. 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.

...

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.
