This article introduces the relevant knowledge of "how to use Python to make Nine Palace Pictures". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Principle

1. The Nine Miyagi Image Generator made by Python is used to package exe files. Users do not need to deploy and install the Python development environment to run the program locally to quickly generate the Nine Miyagi image.

2. Use the PIL library to constantly draw small areas, cut them off and save them into new small pictures.

Example

Suppose that the width and height of each lattice are w and h respectively, then the coordinates of the upper left corner and the lower right corner of the row row (counting from 0) and column col (counting from 0) are (col * w, row * h), (col * w + w, r * h + h), respectively.
