Python Wand path_elliptic_arc()用法及代碼示例

path_elliptic_arc()是專門為路徑引入的函數。 path_elliptic_arc()將從當前點繪製一個橢圓弧到要繪製弧的特定點。
讓我們看看此函數所需的參數。

用法：

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

參數：

參數	輸入類型	描述
to	序列或(數字。實數，數字。實數)	對，代表要繪製的坐標。
radius	collections.abc.sequence或(numbers.Real，numbers.Real)	代表繪製半徑的橢圓對。
rotate	bool	度以在x軸上旋轉橢圓。
large_arc	bool	繪製最大可用弧。
clockwise	bool	從起點到目標順時針繪製弧線路徑。
relative	bool	將給定的坐標視為相對於當前點。

例：畫一條橢圓曲線。

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")
