Python batch generates images of any size

Achieve the effect

Use the source image to generate 1000 images ranging from 1*1 to 1000*1000 pixels in the /img directory of the current working directory.

The effect is as follows:

Directory structure

Implementation example

# -*- coding: utf-8 -*-
import threading

from PIL import Image

image_size = range(1, 1001)


def start():
  for size in image_size:
    t = threading.Thread(target=create_image, args=(size,))
    t.start()


def create_image(size):
  pri_image = Image.open("origin.png")
  pri_image.resize((size, size), Image.ANTIALIAS).save("img/png_%d.png" % size)


if __name__ == "__main__":
  start()

Note: This project needs to reference the PIL library.

Here, we use the resize function.

Like most script libraries, the resize function also supports chained calls. First specify the size and quality through resize((size, size), Image.ANTIALIAS), where for parameter two:

Image.NEARESTLow qualityImage.BILINEARBilinearImage.BICUBIC cubic spline interpolationImage.ANTIALIASHigh Quality

parameter Value	##Meaning

Final call

save("img/png_%d.png" % size) method , writes to the specified location in the specified format.

In addition, considering that it is a large number of linearly intensive operations, multi-thread concurrency is used.

Conclusion

The above is the entire content of using Python to batch generate images of any size. I hope it will be helpful for everyone to learn and use Python. .
