Python中的 Wand path_horizontal_line()函数

path_horizontal_line()是路径的另一个函数。 path_horizontal_line()函数生成从目标点到特定 x 点的水平线。它仅将参数中的 x 作为绘制线的点。

Syntax: wand.drawing.path_horizontal_line(to, relative)

Parameters:

Parameter	Input Type	Description
x	Real	x-axis point to draw to.
relative	bool	treat given coordinates as relative to current point.

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.fill_color = Color('white')
    draw.path_start()
      
    # Start middle-left
    draw.path_move(to=(10, 50))
      
    # horizontal line to x=100
    draw.path_horizontal_line(100)
    draw.path_finish()
    with Image(width=200,
               height=200,
               background=Color('lightgreen')) as image:
          
        draw(image)
        image.save(filename="pathhline.png")

输出：

示例 #2：

from wand.drawing import Drawing
from wand.color import Color
   
with Drawing() as draw:
    draw.stroke_width = 2
    draw.stroke_color = Color('black')
    draw.fill_color = Color('white')
    draw.path_start()
      
    # Start middle-left
    draw.path_move(to=(100, 50))
      
    # horizontal line to x=50
    draw.path_horizontal_line(50)
    draw.path_finish()
    with Image(width=200, 
               height=200,
               background=Color('lightgreen')) as image:
          
        draw(image)
        image.save(filename="pathhline.png")

输出：
