ClipperBase
Overzicht
ClipperBase is een klasse in Aspose.Page FOSS voor Python.
Deze klasse biedt 35 methoden voor het werken met ClipperBase objecten in Python programma’s. Beschikbare methoden zijn: __init__, add_bounds_to_lml, add_path, add_paths, all_horizontal, ascend_to_max, clear, descend_to_min, do_minima_lml, get_bounds, get_last_horz, init_edge, en 23 extra methoden. Alle openbare leden zijn toegankelijk voor elke Python applicatie na het installeren van het Aspose.Page FOSS voor Python pakket. Eigenschappen: current_lm, edges, has_open_paths, minima_list, preserve_collinear, use_full_range.
