Python PIL | ImagePath.Path.tolist() 方法

PIL 是Python Imaging Library，它为Python解释器提供了图像编辑功能。 ImagePath模块用于存储和操作二维矢量数据。路径对象可以传递给ImageDraw模块上的方法。

ImagePath.Path.tolist()将路径转换为Python列表 [(x, y), ...]。

Syntax: PIL.ImagePath.Path.tolist(flat=0)

Parameters:

flat – By default, this function returns a list of 2-tuples [(x, y), …]. If this argument is True, it returns a flat list [x, y, …] instead.

Returns: A list of coordinates.

# from PIL importing ImagePath
from PIL import ImagePath
  
# creating a list to map
getbox = list(zip(range(3, 41, 1), range(11, 22, 2)))
result = ImagePath.Path(getbox)
  
# using tolist function
a = result.tolist()
print(getbox)
print(a)

输出：

[(3, 11), (4, 13), (5, 15), (6, 17), (7, 19), (8, 21)]
[(3.0, 11.0), (4.0, 13.0), (5.0, 15.0), (6.0, 17.0), (7.0, 19.0), (8.0, 21.0)]

另一个例子：改变参数。

# from PIL importing ImagePath
from PIL import ImagePath
  
# creating a list to map
getbox = list(zip(range(5, 51, 16), range(15, 22, 4)))
result = ImagePath.Path(getbox)
  
# using tolist function
a = result.tolist()
print(getbox)
print(a)

输出：

[(5, 15), (21, 19)]
[(5.0, 15.0), (21.0, 19.0)]
