示例1: tree_to_ps
# 需要导入模块: from nltk.draw.util import CanvasFrame [as 别名]
# 或者: from nltk.draw.util.CanvasFrame import canvas()['scrollregion'] [as 别名]
def tree_to_ps(s, outfile):
global _canvas_frame
if _canvas_frame is None:
_canvas_frame = CanvasFrame()
# May throw ValueError:
widget = tree_to_widget(s, _canvas_frame.canvas())
_canvas_frame.canvas()['scrollregion'] = (0, 0, 1, 1)
_canvas_frame.add_widget(widget)
_canvas_frame.print_to_file(outfile)
bbox = widget.bbox()
_canvas_frame.destroy_widget(widget)
## Testing..
#for (key, val) in metrics.items():
