Python中的魔杖旋转（）函数

旋转改变图像的方向或将图像旋转到特定角度。 rotate()的度数可以是 0 到 359。（实际上您可以传递 360、361 或更多，但分别与 0、1 或更多相同。）。

Syntax : 
 

Parameters : 
 

Parameter	Input Type	Description
degree	numbers.Real	a degree to rotate. multiples of 360 affect nothing
background	wand.color.Color	an optional background color. default is transparent.
reset_coords	bool	optional flag. If set, after the rotation, the coordinate frame will be relocated to the upper-left corner of the new image. By default is True.

示例 1：

Python3

wand.image.rotate(degree, background, reset_coords)

Python3

# Import Image from wand.image module
from wand.image import Image
 
with Image(filename ="koala.jpeg") as img:
    with img.clone() as rotated:
        # rotate image using rotate() function
        rotated.rotate(90)
        rotated.save(filename ='transform-rotated-90.jpg')

输出 ：

示例 2：

Python3

# Import Image from wand.image module
from wand.image import Image
from wand.color import Color
 
with Image(filename ="koala.jpeg") as img:
    with img.clone() as rotated:
        # rotate image using rotate() function
        rotated.rotate(135, background = Color('rgb(229, 221, 112)'))
        rotated.save(filename ='transform-rotated-135.jpg')

输出 ：
