About batch generation of 1000 pictures, you can refer to this article: the use of Python batch generation of any size picture

implementation example

Import glob
import OS
import threading

from PIL import Image


def create_image (infile, index):
  Os.path.splitext (infile)
  im = Image.open (infile)
  im.save ("Img_webp/webp_" + str (index) + ". Webp", "WEBP")


def start ():
  index = 0 for
  infile in Glob.glob ("Img/*.png"):
    t = Threading. Thread (Target=create_image, args= (infile, Index,))
    T.start ()
    t.join ()
    index = 1


if __name__ = " __main__ ":
  start ()

Note: This project requires a reference PIL library.

Multithreading concurrency is used in view of the large number of linear-intensive operations. threading.Thread()when you create a thread object, note that the args parameter only accepts meta ancestor.

Here we use the Image.open() function to open the image.

The final calling save("img_webp/webp_" + str(index) + ".webp", "WEBP") method to write to the specified location in the specified format. Where format the parameter is the target format.

Well, the content of this article to this is basically over, we have learned? Hope for everyone's study and work can have certain help.
