效果图：

from PIL import Image

imgSrc = 'test.jpg'
chars = list("⣿⣷⣾⢿⡾⣮⣭⣝⣫⣥⡛⣏⡏⢸⡇⢘⠛⡲⠲⢃⠒⠤⣀⠄")   # 使用的字符
output = '1.txt'

width = 512
height = 512


def getChar(r, g, b, a=256):
    if a == 0:
        return '⠄'
    length = len(chars)
    gray = 0.2126 * r + 0.7152 * g + 0.0722 * b    # 灰度计算
    block = (256.0 + 1) / length
    return chars[int(gray / block)]


txt = ''
img = Image.open(imgSrc)
img = img.resize((width, height), Image.NEAREST)
imgWidth = img.width
imgHeight = img.height

for i in range(imgHeight):
    for j in range(imgWidth):
        txt += getChar(*img.getpixel((j, i)))
    txt += 'n'
img.close()

with open(output, mode='w', encoding='utf-8') as f:
    f.write(txt)
