  ORIGINAL = qgisprocess:::qgis_default_value(),
  CORRECTED = qgisprocess:::qgis_default_value(),
  AZI = qgisprocess:::qgis_default_value(),
  HGT = qgisprocess:::qgis_default_value(),
  METHOD = qgisprocess:::qgis_default_value(),
  MINNAERT = qgisprocess:::qgis_default_value(),
  MAXCELLS = qgisprocess:::qgis_default_value(),
  MAXVALUE = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

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.
