要求图片是正方形，否则效果不太好。

from PIL import Image
from sys import argv

PATH = os.getcwd()+'\\'
imgname = argv[1]
IMG = PATH + imgname # 获得图片文件的路径+文件名
WIDTH = 120

11.27更新
在字符画的基础上，可以生成字符联播，像小视频一样。这里的参考资料是：殷缘星 https://www.cnblogs.com/kirito-c/p/5971988.html

我分了好几个程序实现：
- 先用Mp42Png.py实现视频分解成图片，
- 再用zifuhua.py生成文本文件，
- 最后用player.py播放出来。
最后一步与参考资料不同，采用了python的界面工具Tkinter，但不知为什么，定时器设置为21ms刷新一张图片就太慢了，而20ms刷新一次就太快了，很迷，所以也没有加入音乐，目前只是一个半成品。
代码如下：
# Mp42Png.py
# https://www.cnblogs.com/kirito-c/p/5971988.html
# 分解视频的程序，直接copy了参考资料里的
# 此程序有个bug，视频逐帧分解完了之后还在运行，除非ctrl+C
import numpy as np
import cv2
import os
cap = cv2.VideoCapture('argv[1]')
num = 0
while (cap.isOpened()):
print('pic',num)
ret, frame = cap.read()
# gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
cv2.imwrite(os.getcwd()+'\\pictures\\img%d.png' % num, frame)
num += 1
print('finish')
# zifuhua.py
# 字符画生成的程序，每帧生成一个文本文件，存放在 当前目录\text\文件夹中
from PIL import Image
from sys import argv
import os
IMGPATH = os.getcwd()+'\\pictures\\'
WIDTH = 160
HEIGHT = 60
# OUTPUT = os.getcwd()+'\\zifuhua.txt'
IMGNUM = sum([len(x) for _, _, x in os.walk(os.path.dirname(IMGPATH+'img0.png'))]) # 得到\picture\目录中有多少文件
TXTPATH = os.getcwd()+'\\text\\'
ascii_char = list("$*+. ")
def get_char(r,b,g,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)]
if __name__ == '__main__':
x = 0
while x< IMGNUM:
f = open(TXTPATH+'txt'+str(x)+'.txt','w')
im = Image.open(IMGPATH+'img'+str(x)+'.png')
im = im.resize((WIDTH,HEIGHT),Image.NEAREST)
txt = ""
for i in range(HEIGHT):
for j in range(WIDTH):
txt += get_char(*im.getpixel((j,i)))
txt += '\n'
print('finish %d',x)
f.write(txt)
x = x+1
f.close()
# 看播放效果
# 思路是在界面上放一个文本框，用合适的频率不断刷新这个文本框
# 遗憾的是我并没有找到合适的频率

FRAMETIME = 20 # 20ms播放一帧
window = Tkinter.Tk() # 放置窗体
window.title('Bad Apple Player') # 修改窗体标题
window.geometry('1000x850') # 修改窗体大小
txtpage = ""
player = Tkinter.Label(window,text = txtpage,width=800,height=600,font=('Consolas',8),justify="left") # 设置文本框初始值
player.pack() # 放置文本框
x = 1 # x表示当前帧数
# 定时器处理函数
def trickit():
global x
global time1
txtpage = ""
f = open(TXTPATH+'txt'+str(x)+'.txt','r')
for line in f:
txtpage = txtpage + line
player.config(text = txtpage)
window.update()
f.close()
x += 1
if x <= IMGNUM:
player.after(FRAMETIME, trickit)
player.after(0, trickit) # 激活定时器
window.mainloop()

这是生成的效果，生成gif的软件是ScreenToGif 2，又小又轻便，大赞！
