使用PIL将图片转成字符

注意：转化成txt后，txt的字体使用“宋体”，不能使用“微软雅黑”，否则图像会变形

import numpy as np
from PIL import Image

if __name__ == \'__main__\':
    image_file = \'huarun3.png\'
    height = 100

    img = Image.open(image_file)
    img_width, image_height = img.size
    print(\'img_width:\', img_width)
    print(\'image_height:\', image_height)
    width = int(height / image_height * img_width * 2)
    img = img.resize((width, height), Image.ANTIALIAS)
    print(img)

    img_l = img.convert(\'L\')
    pixels = np.array(img_l)
    print(img_l)

    chars = \'MNHQ$OC?7>!:-;. \'
    step = 256 // len(chars)
    result = \'\'
    for i in range(height):
        for j in range(width):
            result += chars[pixels[i][j] // step]
        result += \'\n\'

    with open(image_file + \'.txt\', mode=\'w\') as f:
        f.write(result)
