Send a high-fashion friend in Python

Today I want to introduce you to a python library: the

PIL(python Image Library)

Here's a real-world example of what magic 50 lines of python code can do.

This is a circle of friends sent, before the cut is a picture, after the cut is nine pictures, successfully dominated the screen

In addition to working with regular square images, you can also work with non-regular images. For example, how do you handle the following image, which is much wider than its height?

It's simple, take the larger value between the width and height and fill it with white to construct a square image.

Of course, it's easy to make a picture look like this, as many photo manipulation apps on your phone can do it now.

This example is given just to give you an idea of PIL Library If you are interested in programming, you can also practice it.

All right, now check this out. PIL Library What the hell is it?

PIL is a very powerful Python image processing standard library, but then, since PIL supports Python 2.7, the The programmers who use Python3 have separated out another branch of PIL and created another library, Pillow, that is Python3-capable . Pillow is compatible with most of the syntax of PIL and is very easy to use.

Here's how the PIL library was used to implement the applet described above.

The idea is actually quite simple.

The corresponding codes are as follows.

I believe that you know how to implement the code, the code may be difficult to understand the corresponding comments are also given, you quickly download the code to take a run.

github address.

Finally, some students asked in the background whether there is any crawler, Python basic class book recommendations, here I recommend two very good books, "Fluent Python" and "Python3 web crawler development practice", but also welcome you to leave a message you feel good python books.
