Python Wand circle()用法及代碼示例

circle()函數是Wand中的另一個繪圖函數。此方法用於在圖像中繪製圓。它僅需要兩個參數，即圓的原點和周長。

用法： wand.drawing.circle(origin, perimeter)

參數：

參數	輸入類型	描述
origin	(collections.abc.Sequence)或(實數，數字。實數)	表示圓的原點x和y的一對。
perimeter	(collections.abc.Sequence)或(實數，數字。實數)	對，代表圓的周長x和y

範例1：

# Import required objects from wand modules 
from wand.image import Image 
from wand.drawing import Drawing 
from wand.color import Color 
  
# generate object for wand.drawing 
with Drawing() as draw:
  
    # set stroke color 
    draw.stroke_color = Color('black') 
  
    # set width for stroke 
    draw.stroke_width = 1
  
    # fill white color in arc 
    draw.fill_color = Color('white') 
    origin = (100, 100) 
    perimeter = (50, 50) 
  
    # draw circle using circle() function 
    draw.circle(origin, perimeter)  
    with Image(width = 200, 
               height = 200, 
               background = Color('green')) as img:
  
        # draw shape on image using draw() function 
        draw.draw(img) 
        img.save(filename ='circle.png')

輸出：

範例2：
輸入圖片：

# Import required objects from wand modules 
from wand.image import Image 
from wand.drawing import Drawing 
from wand.color import Color 
  
# generate object for wand.drawing 
with Drawing() as draw:
    origin = (100, 100) 
    perimeter = (50, 50) 
  
    # set stroke color 
    draw.stroke_color = Color('black') 
  
    # set width for stroke 
    draw.stroke_width = 1
  
    # fill white color in arc 
    draw.fill_color = Color('white') 
  
    # draw bezier curve using bezier function 
    draw.circle(origin, perimeter) 
    with Image(filename ="gog.png") as img:
  
        # draw shape on image using draw() function 
        draw.draw(img) 
        img.save(filename ='circle2.png')

輸出：
