ClipperBase
概述
ClipperBase 是 Aspose.Page FOSS 中用于 Python 的类。
此类提供 35 个方法,用于在 Python 程序中处理 ClipperBase 对象。可用的方法包括:__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,以及另外 23 个方法。安装 Aspose.Page FOSS for Python 包后,所有公共成员对任何 Python 应用程序均可访问。属性:current_lm、edges、has_open_paths、minima_list、preserve_collinear、use_full_range。
