Using Python to generate pictures of any size in batches _python

Implementation effect

From the source picture, in the current working directory in the/IMG directory to generate 1000 pieces, from 1*1 to 1000*1000 pixels of the picture.

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 requires a reference PIL library.

Here, we use resize functions.

Like most script libraries, resize functions also support chained calls. First by resize((size, size), Image.ANTIALIAS) specifying the size and quality, which for parameter two:

Parameter values	Meaning
Image.nearest	Low quality
Image.bilinear	Bilinear
Image.bicubic	Three cubic spline interpolation
Image.antialias	Quality

The final calling save("img/png_%d.png" % size) method to write to the specified location in the specified format.

In addition, multithreading concurrency is used in view of the large number of linear-intensive operations.

Conclusion

The above is the use of Python batch production of any size pictures of the entire content, I hope to learn and use Python can help.
