处理图片为字符，输出为txt文件（Python）

处理简单的图片效果会更好一些

# coding:UTF-8
from PIL import Image
import os

def main():
    # 获取当前工作目录
    file_path = os.getcwd()

    # 遍历所有文件
    for file in os.listdir(file_path):
        # 获取文件后缀
        suff_name = os.path.splitext(file)[1]

        # 过滤非pdf格式文件
        if suff_name != '.jpg':
            continue
        # 获取文件名称
        file_name = os.path.splitext(file)[0]
        # jpg文件名称
        jpg_name = os.getcwd() + '\\' + file
        # 要转换的txt文件名称
        txt_name = os.getcwd() + '\\' + file_name + '.txt'

        ascii_char = list("$@B%8&WM#*oahkbdpqwmZO0QLCJUYXzcvunxrjft/\|()1{}[]?-_+~<>i!lI;:,\"^`'. ")
        openl(ascii_char,jpg_name,txt_name)


    # 将256灰度映射到70个字符上
def get_char(ascii_char,r, g, b, alpha=256):
        if alpha == 0:
            return ' '
        length = len(ascii_char)
        gray = int(0.2126 * r + 0.7152 * g + 0.0722 * b)

        unit = (256.0 + 1) / length
        return ascii_char[int(gray / unit)]

def openl(scii_char,jpg_name,txt_name):
    WIDTH = 140
    HEIGHT = 40
    im = Image.open(jpg_name)
    im = im.resize((WIDTH, HEIGHT), Image.Dither.NONE)

    txt = ""

    for i in range(HEIGHT):
        for j in range(WIDTH):
            txt += get_char(scii_char,*im.getpixel((j, i)))
        txt += '\n'

    print(txt)

    # 字符画输出到文件
    with open(txt_name, 'w') as f:
        f.write(txt)
main()
