qgis_affinetransform: QGIS algorithm - Affine transform

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

QGIS algorithm - Affine transform

Description

QGIS Algorithm provided by QGIS (native c++) Affine transform (native:affinetransform). Applies an affine transformation to geometries. Applies an affine transformation to the geometries from a layer. Affine transformations can include translation, scaling and rotation. The operations are performed in a scale, rotation, translation order. Z and M values present in the geometry can also be translated and scaled independently.

Usage

qgis_affinetransform(
  INPUT = qgisprocess:::qgis_default_value(),
  DELTA_X = qgisprocess:::qgis_default_value(),
  DELTA_Y = qgisprocess:::qgis_default_value(),
  DELTA_Z = qgisprocess:::qgis_default_value(),
  DELTA_M = qgisprocess:::qgis_default_value(),
  SCALE_X = qgisprocess:::qgis_default_value(),
  SCALE_Y = qgisprocess:::qgis_default_value(),
  SCALE_Z = qgisprocess:::qgis_default_value(),
  SCALE_M = qgisprocess:::qgis_default_value(),
  ROTATION_Z = 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.
DELTA_X	distance - Translation (x-axis). 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.
DELTA_Y	distance - Translation (y-axis). 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.
DELTA_Z	number - Translation (z-axis). 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.
DELTA_M	number - Translation (m 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.
SCALE_X	number - Scale factor (x-axis). 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.
SCALE_Y	number - Scale factor (y-axis). 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.
SCALE_Z	number - Scale factor (z-axis). 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.
SCALE_M	number - Scale factor (m 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.
ROTATION_Z	number - Rotation around z-axis (degrees counter-clockwise). 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 - Transformed. 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.
