In JanCaha/r_package_qgis: An extension of package "qgisprocess" providing direct R functions for QGIS functions

QGIS algorithm - Clip raster by extent

Description

QGIS Algorithm provided by GDAL Clip raster by extent (gdal:cliprasterbyextent). —————- Arguments —————- INPUT: Input layer Argument type: raster Acceptable values: - Path to a raster layer PROJWIN: Clipping extent Argument type: extent Acceptable values: - A comma delimited string of x min, x max, y min, y max. E.g. '4,10,101,105' - Path to a layer. The extent of the layer is used. OVERCRS: Override the projection for the output file Default value: false 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 NODATA: Assign a specified NoData value to output bands (optional) Argument type: number Acceptable values: - 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 OPTIONS: Additional creation options (optional) Default value: Argument type: string Acceptable values: - String 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 DATA_TYPE: Output data type Default value: 0 Argument type: enum Available values: - 0: Use Input Layer Data Type - 1: Byte - 2: Int16 - 3: UInt16 - 4: UInt32 - 5: Int32 - 6: Float32 - 7: Float64 - 8: CInt16 - 9: CInt32 - 10: CFloat32 - 11: CFloat64 - 12: Int8 Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3' EXTRA: Additional command-line parameters (optional) Argument type: string Acceptable values: - String 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 OUTPUT: Clipped (extent) Argument type: rasterDestination Acceptable values: - Path for new raster layer

Usage

gdal_cliprasterbyextent(
  INPUT = qgisprocess:::qgis_default_value(),
  PROJWIN = qgisprocess:::qgis_default_value(),
  OVERCRS = qgisprocess:::qgis_default_value(),
  NODATA = qgisprocess:::qgis_default_value(),
  OPTIONS = qgisprocess:::qgis_default_value(),
  DATA_TYPE = qgisprocess:::qgis_default_value(),
  EXTRA = qgisprocess:::qgis_default_value(),
  OUTPUT = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT	raster - Input layer. Path to a raster layer.
PROJWIN	extent - Clipping extent. A comma delimited string of x min, x max, y min, y max. E.g. '4,10,101,105'. Path to a layer. The extent of the layer is used..
OVERCRS	boolean - Override the projection for the output file. 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.
NODATA	number - Assign a specified NoData value to output bands. 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.
OPTIONS	string - Additional creation options. String 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.
DATA_TYPE	enum of ⁠("Use Input Layer Data Type", "Byte", "Int16", "UInt16", "UInt32", "Int32", "Float32", "Float64", "CInt16", "CInt32", "CFloat32", "CFloat64", "Int8")⁠ - Output data type. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
EXTRA	string - Additional command-line parameters. String 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.
OUTPUT	rasterDestination - Clipped (extent). Path for new raster layer.
...	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.
