1. Preview of special effects

Before treatment

After treatment

After the details are enlarged

II. Program principle

Map 256 grayscale of the picture to the corresponding characters

That is, the RGB value is converted to the corresponding character.

Then write the characters to the file.

Do you understand me?

Third, the program source code #! / usr/bin/env python# encoding: utf-8from PIL import Image class charsetPicture:''This is a main Class, the file contains all documents. One document contains paragraphs that have several sentences It loads the original file and converts the original file to new content Then the new content will be saved by this class''def _ _ init__ (self): self.char = list ("$@ B%8&WM#*oahkbdpqwmZO0QLCJUYXzcvunxrjft/\ | () 1 {} []?-_ + ~ itransitive init__,\" ^ `'.
