Python PIL | ImageChops.screen() 和 ImageChops.offset() 方法

PIL 是Python Imaging Library，它为Python解释器提供了图像编辑功能。

ImageChops.screen() 方法 –

该方法用于将两个倒置图像叠加在一起。

Syntax: ImageChops.screen(image1, image2)

Parameters:
image1 first image
image2 second image

Return Value: An Image

Python3

# This will import Image and ImageChops modules
from PIL import Image, ImageChops
 
# Opening Images
im = Image.open(r"C:\Users\Admin\Pictures\images.png")
im2 = Image.open(r"C:\Users\Admin\Pictures\download.PNG")
 
# superimposing images im and im2
im3 = ImageChops.screen(im, im2)
 
# showing resultant image
im3.show()

输出：

ImageChops.offset() 方法 –

此方法返回图像的副本，其中数据已偏移给定距离。数据环绕边缘。如果省略 yoffset，则假定它等于 xoffset。

Syntax: ImageChops.offset(image1, xoffset, yoffset = None)
Parameters: 
image: It is the image on which offset is provided 
xoffset: the horizontal distance 
yoffset: it is the vertical distance, if omitted both distance are set to same.
Return value: Copy of the original image 
 

Python3

# This will import Image and ImageChops modules
from PIL import Image, ImageChops
 
# Opening Images
im = Image.open(r"C:\Users\Admin\Pictures\images.png")
im2 = Image.open(r"C:\Users\Admin\Pictures\download.PNG")
 
# Here, xoffset is given 100
# yoffset wil automatically set to 100
im3 = ImageChops.offset(im, 140)
 
# showing resultant image
im3.show()

输出：
