QGIS algorithm - Principal component based image sharpening

Description

QGIS Algorithm provided by SAGA Next Gen Principal component based image sharpening (sagang:principalcomponentbasedimagesharpening). —————- Arguments —————- GRIDS: Original Channels Argument type: multilayer PAN: Panchromatic Channel Argument type: raster Acceptable values: - Path to a raster layer SHARPEN: Sharpened Channels Argument type: rasterDestination Acceptable values: - Path for new raster layer METHOD: Method Default value: 1 Argument type: enum Available values: - 0: (0) correlation matrix - 1: (1) variance-covariance matrix - 2: (2) sums-of-squares-and-cross-products matrix Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3' RESAMPLING: Resampling Default value: 2 Argument type: enum Available values: - 0: (0) nearest neighbour - 1: (1) bilinear - 2: (2) cubic convolution Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3' PAN_MATCH: Panchromatic Channel Matching Default value: 1 Argument type: enum Available values: - 0: (0) normalized - 1: (1) standardized Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3' OVERWRITE: Overwrite Default value: true Argument type: boolean Acceptable values: - 1 for true/yes - 0 for false/no - 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

Usage

sagang_principalcomponentbasedimagesharpening(
  GRIDS = qgisprocess:::qgis_default_value(),
  PAN = qgisprocess:::qgis_default_value(),
  SHARPEN = qgisprocess:::qgis_default_value(),
  METHOD = qgisprocess:::qgis_default_value(),
  RESAMPLING = qgisprocess:::qgis_default_value(),
  PAN_MATCH = qgisprocess:::qgis_default_value(),
  OVERWRITE = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

GRIDS	multilayer - Original Channels. .
PAN	raster - Panchromatic Channel. Path to a raster layer.
SHARPEN	rasterDestination - Sharpened Channels. Path for new raster layer.
METHOD	enum of ⁠("(0) correlation matrix", "(1) variance-covariance matrix", "(2) sums-of-squares-and-cross-products matrix")⁠ - Method. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
RESAMPLING	enum of ⁠("(0) nearest neighbour", "(1) bilinear", "(2) cubic convolution")⁠ - Resampling. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
PAN_MATCH	enum of ⁠("(0) normalized", "(1) standardized")⁠ - Panchromatic Channel Matching. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
OVERWRITE	boolean - Overwrite. 1 for true/yes. 0 for false/no. 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.
