This article mainly explains how python changes the size of all the pictures in the folder. Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how python resizes all the pictures in the folder.

Specific operation methods:

1. First, you need to import the os module in the python script.

Import os

2. define the width, height and folder path of the picture.

3. Use the os.listdir () function to read the folder.

4. Customize a method to set the intercept size from the center of the image.

5. Finally, traverse all the pictures in the folder.

The code example is as follows:

# www.xieniao.com

# Import module

Import os

From PIL import Image,ImageDraw,ImageFont

# take iphone5 resolution as an example

W = 640

H = 1136

Path = "/ Users/U/workspace/python learning/0005/" # Picture directory

Dir = os.listdir (path) # read file directory

Def crop (str):

# intercept from the image center

Size= (

(im.size [0]-w) / 2

(im.size [1]-h) / 2

(im.size [0] + w) / 2

(im.size [1] + h) / 2)

Imcrop = im.crop (size)

Imcrop.save (path + '.clients' + file, im.format)

For file in dir: # traversing directories

# if os.path.splitext (file) [1] = '.png': # identify the file type by suffix method, one icon type at a time

# another way

Try:

With Image.open (path+file) as im:

# print (im.format) # print picture file type

Crop (file)

Except IOError:
