Arguments

BANDS

multilayer - Bands. .

MEAN

rasterDestination - Mean Distance. Path for new raster layer.

STDDEV

rasterDestination - Standard Deviation. Path for new raster layer.

DIFF

rasterDestination - Distance. Path for new raster layer.

RADIUS

number - Radius (Cells). 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.

DW_WEIGHTING

enum of ("(0) no distance weighting", "(1) inverse distance to a power", "(2) exponential", "(3) gaussian") - Weighting Function. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

DW_IDW_POWER

number - Power. 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.

DW_BANDWIDTH

number - Bandwidth. 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.
