Python中的魔杖path_start（）函数

我们还可以在wand.drawing模块中绘制路径。每个路径方法都需要一个目标点，并将从当前点绘制到新点。目标点将成为下一个应用路径方法的新当前点。 wand 中的路径由一些其他方法组成，用于在路径中绘制不同的图形。
在本文中，我们将学习 path_start()函数。使用 path_start函数启动路径。

Syntax: wand.drawing.path_start()

示例 #1：

from wand.image import Image
from wand.drawing import Drawing
from wand.color import Color
  
with Drawing() as draw:
    draw.stroke_width = 2
    draw.stroke_color = Color('black')
    draw.path_start()
      
    # Start middle-left
    draw.path_move(to =(100, 100))
    draw.path_horizontal_line(1)
      
    # Close first & last points
    draw.path_close()
    draw.path_finish()
    with Image(width = 200, 
               height = 200,
               background = Color('green')) as image:
          
        draw(image)
        image.save(filename = "pathstart.png")

输出：

示例 #2：

from wand.image import Image
from wand.drawing import Drawing
from wand.color import Color
   
with Drawing() as draw:
    draw.stroke_width = 2
    draw.stroke_color = Color('black')
    draw.path_start()
      
    # Start middle-left
    draw.path_move(to=(100, 100))
      
    # draw a vertical line from path initial point
    draw.path_vertical_line(1)
      
    # Close first & last points
    draw.path_close()
    draw.path_finish()
    with Image(width=200,
               height=200,
               background=Color('green')) as image:
        draw(image)
        image.save(filename = "pathstart.png")

输出：
