How to use Python to merge multiple pictures into one picture

In daily life and work, we often need to merge multiple pictures into one picture. For example, merge multiple photos into one album cover, merge multiple images into one PDF file, etc. This function can be easily implemented using Python. This article will introduce how to use Python to merge multiple pictures into one picture, with code examples.

First, we need to install the Pillow library. Enter the following command on the command line to install:

pip install pillow

Next, let’s take a look at the specific code implementation.

from PIL import Image

# 打开多张图片
image1 = Image.open("image1.jpg")
image2 = Image.open("image2.jpg")
image3 = Image.open("image3.jpg")

# 获取图片的宽度和高度
width, height = image1.size

# 创建一张新的图片，大小为所有图片总宽度和高度
new_image = Image.new('RGB', (width*3, height))

# 将图片粘贴到新的图片中
new_image.paste(image1, (0, 0))
new_image.paste(image2, (width, 0))
new_image.paste(image3, (width*2, 0))

# 保存合并后的图片
new_image.save("merged_image.jpg")

The above code uses the Image module in the Pillow library to process images. First, we open multiple images through the Image.open() function. Then, use the size properties to get the width and height of one of the images. Next, we create a new image that is the total width and height of all images so that it can accommodate all the images. Next, use the paste() function to paste each picture into a new picture, specifying the paste position of each picture. Finally, use the save() function to save the merged image locally.

Using the above code example, we can easily merge multiple pictures into one picture. You can freely modify the code according to actual needs, such as adjusting the pasting position of pictures, the order of merging, etc. Of course, you can also write more complex picture merging logic according to your own needs.

To summarize, this article introduces how to use Python to merge multiple pictures into one picture, and attaches code examples. I hope this article will be helpful to you and allow you to process multiple images more conveniently.
