Python Wand Drawing()用法及代码示例

魔杖的另一个模块是wand.drawing。该模块为我们提供了一些非常基本的绘图函数。 wand.drawing.Drawing对象缓冲用于将形状绘制为图像的指令，然后可以将这些形状绘制为零个或多个图像。

用法： with Drawing() as draw:

Note:In the above syntax “as draw” is just a nomenclature and can be any string as needed. The Drawing function in Python wand take has no parameter.

范例1：

# Import important objects from wand library 
from wand.image import Image 
from wand.drawing import Drawing 
from wand.color import Color 
  
# Create draw object using Drawing() function 
with Drawing() as draw:
    with Image(width = 200, 
               height = 200, 
               background = Color('green')) as img:
        draw(img) 
        img.save(filename ='empty.gif')

输出图像：

with Drawing() as draw:
    draw.stroke_color = Color('black') 
    draw.stroke_width = 2
    draw.line((5, 5), (45, 50)) 
    with Image(width = 200, 
               height = 200,
