qgis_orthogonalize: QGIS algorithm - Orthogonalize

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

QGIS algorithm - Orthogonalize

Description

QGIS Algorithm provided by QGIS (native c++) Orthogonalize (native:orthogonalize). Takes a line or polygon layer and attempts to orthogonalize all the geometries in the layer. This process shifts the nodes in the geometries to try to make every angle in the geometry either a right angle or a straight line. The angle tolerance parameter is used to specify the maximum deviation from a right angle or straight line a node can have for it to be adjusted. Smaller tolerances mean that only nodes which are already closer to right angles will be adjusted, and larger tolerances mean that nodes which deviate further from right angles will also be adjusted. The algorithm is iterative. Setting a larger number for the maximum iterations will result in a more orthogonal geometry at the cost of extra processing time.

Usage

qgis_orthogonalize(
  INPUT = qgisprocess:::qgis_default_value(),
  ANGLE_TOLERANCE = qgisprocess:::qgis_default_value(),
  MAX_ITERATIONS = qgisprocess:::qgis_default_value(),
  OUTPUT = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT	source - Input layer. Path to a vector layer.
ANGLE_TOLERANCE	number - Maximum angle tolerance (degrees). 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.
MAX_ITERATIONS	number - Maximum algorithm iterations. 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.
OUTPUT	sink - Orthogonalized. Path for new vector 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.
