Arguments

GRID

raster - Grid. Path to a raster layer.

CONTRAST

rasterDestination - Contrast. Path for new raster layer.

ENERGY

rasterDestination - Energy. Path for new raster layer.

ENTROPY

rasterDestination - Entropy. Path for new raster layer.

VARIANCE

rasterDestination - Variance. Path for new raster layer.

TYPE

enum of ("(0) square", "(1) circle") - Kernel. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

RADIUS

number - Radius. 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.

NORMALIZE

enum of ("(0) no", "(1) scale to range") - Normalization. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

NORM_MIN

number - Minimum. 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.

NORM_MAX

number - Maximum. 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.

...

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.
