Arguments

INPUT

raster - Input layer. Path to a raster layer.

BAND

band - Band number. Integer value representing an existing raster band number.

Z_FACTOR

number - Z factor (vertical exaggeration). A numeric value.

SCALE

number - Scale (ratio of vertical units to horizontal). A numeric value.

AZIMUTH

number - Azimuth of the light. A numeric value.

ALTITUDE

number - Altitude of the light. A numeric value.

COMPUTE_EDGES

boolean - Compute edges. 1 for true/yes. 0 for false/no.

ZEVENBERGEN

boolean - Use Zevenbergen&Thorne formula instead of the Horn's one. 1 for true/yes. 0 for false/no.

COMBINED

boolean - Combined shading. 1 for true/yes. 0 for false/no.

MULTIDIRECTIONAL

boolean - Multidirectional shading. 1 for true/yes. 0 for false/no.

OPTIONS

string - Additional creation options. String value.

EXTRA

string - Additional command-line parameters. String value.

OUTPUT

rasterDestination - Hillshade. Path for new raster layer.

...

further parameters passed to qgisprocess::qgis_run_algorithm()

.complete_output

logical specifing 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.
