Solution: To identify self encircled lines you can extract by expression with the following formula: $geometry = make_polygon($geometry) AND num_points($geometry) = num_points(make_polygon($geometry)) This expression checks if the geometry of the line can be converted into a polygon and ensures that the number of points in the original line matches the number of points in the resulting polygon. This helps to ensure that the line forms a closed shape by itself.

I have a temporary vector file from a qgis processing.run() (basically a line shapefile temporary output): gis_osm_roads_free_1_lyr = results['Gis_osm_roads_free_1'] I have a map_item: map_item = layout.itemById('Map 1') I have a list of aspect ratios: aspect_ratios = [(350, 300),(130,180), (180, 240), (150, 200), (150, 210)] There are more of aspect ratio values but these are just for the question.
