qgis_rasterlayerhistogram.Rd
QGIS Algorithm provided by QGIS Raster layer histogram (qgis:rasterlayerhistogram). This algorithm generates a histogram with the values of a raster layer. The raster layer must have a single band.
qgis_rasterlayerhistogram(
INPUT = qgisprocess:::qgis_default_value(),
BAND = qgisprocess:::qgis_default_value(),
BINS = qgisprocess:::qgis_default_value(),
OUTPUT = qgisprocess:::qgis_default_value(),
...,
.complete_output = .complete_output_option(),
.quiet = .quiet_option(),
.messages = .message_option()
)
raster
- Input layer. Path to a raster layer.
band
- Band number. Integer value representing an existing raster band number.
number
- number of bins. 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.
fileDestination
- Histogram. Path for new file.
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
.
