QGIS algorithm - Remove duplicate vertices — qgis

QGIS Algorithm provided by QGIS (native c++) Remove duplicate vertices (native:removeduplicatevertices). This algorithm removes duplicate vertices from features, wherever removing the vertices does not result in a degenerate geometry. The tolerance parameter specifies the tolerance for coordinates when determining whether vertices are identical. By default, z values are not considered when detecting duplicate vertices. E.g. two vertices with the same x and y coordinate but different z values will still be considered duplicate and one will be removed. If the Use Z Value parameter is true, then the z values are also tested and vertices with the same x and y but different z will be maintained. Note that duplicate vertices are not tested between different parts of a multipart geometry. E.g. a multipoint geometry with overlapping points will not be changed by this method.

Arguments

INPUT: source - Input layer. Path to a vector layer.
TOLERANCE: distance - Tolerance. 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.
USE_Z_VALUE: boolean - Use Z Value. 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.
OUTPUT: sink - Cleaned. 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.
