sec_interp.core.utils.geometry_utils.extraction module

Geometry extraction utilities.

sec_interp.core.utils.geometry_utils.extraction.extract_all_vertices(geometry: qgis.core.QgsGeometry) → list[qgis.core.QgsPointXY]

Extract all vertices from any QGIS geometry type.

Parameters:

geometry – The input QGIS geometry.

Returns:

A flat list of all vertices found in the geometry.

sec_interp.core.utils.geometry_utils.extraction.extract_lines_from_geometry(geometry: qgis.core.QgsGeometry) → list[qgis.core.QgsGeometry]

Extract individual LineString geometries from a (possibly Multi) geometry.

If the input is a MultiLineString, it decomposes it into its constituent parts. If it’s a single LineString, it returns it in a list.

Parameters:

geometry – Input geometry (LineString or MultiLineString).

sec_interp.core.utils.geometry_utils.extraction.get_line_vertices(geometry: qgis.core.QgsGeometry) → list[qgis.core.QgsPointXY]

Extract vertices specifically from a line or multiline geometry.

Parameters:

geometry – A QGIS geometry of type LineGeometry.

Returns:

A flat list of vertices.

Raises:

ValueError – If the geometry is null, not a line, or contains no vertices.
