Arguments

DEM: raster - Elevation. Path to a raster layer.
ORIGINAL: raster - Original Image. Path to a raster layer.
CORRECTED: rasterDestination - Corrected Image. Path for new raster layer.
AZI: number - Azimuth. 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.
HGT: number - Height. 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.
METHOD: enum of ("(0) Cosine Correction (Teillet et al. 1982)", "(1) Cosine Correction (Civco 1989)", "(2) Minnaert Correction", "(3) Minnaert Correction with Slope (Riano et al. 2003)", "(4) Minnaert Correction with Slope (Law & Nichol 2004)", "(5) C Correction", "(6) Normalization (after Civco, modified by Law & Nichol)") - Method. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
MINNAERT: number - Minnaert Correction. 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.
MAXCELLS: number - Maximum Cells (C Correction Analysis). 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.
MAXVALUE: enum of ("(0) 1 byte (0-255)", "(1) 2 byte (0-65535)") - Value Range. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
...: 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.
