Python Wand path_elliptic_arc()用法及代码示例

path_elliptic_arc()是专门为路径引入的函数。 path_elliptic_arc()将从当前点绘制一个椭圆弧到要绘制弧的特定点。
让我们看看此函数所需的参数。

用法：

wand.drawing.path_elliptic_arc(to, radius, rotation, large_arc, clockwise, relative)

参数：

参数	输入类型	描述
to	序列或(数字。实数，数字。实数)	对，代表要绘制的坐标。
radius	collections.abc.sequence或(numbers.Real，numbers.Real)	代表绘制半径的椭圆对。
rotate	bool	度以在x轴上旋转椭圆。
large_arc	bool	绘制最大可用弧。
clockwise	bool	从起点到目标顺时针绘制弧线路径。
relative	bool	将给定的坐标视为相对于当前点。

例：画一条椭圆曲线。

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, 100)) 
    # draw elliptical curve 
    draw.path_elliptic_arc(to =(10, 180), 
                           radius = (20, 40), 
                           rotation = 270, 
                           large_arc = True, 
                           clockwise = True, 
                           relative = True ) 
    with Image(width = 200, height = 200, background = Color('lightgreen')) as image:
        draw(image) 
        image.save(filename ="pathecurve.png")

输出：
