PIL(Python Image Library)库是Python平台上一个功能强大的图像处理标准库，支持图像的存储、显示和处理，几乎可以处理所有图片格式，如图像的压缩、裁剪、叠加、添加文字等等。
安装PIL库:pip install pillow
from PIL import Image
ascii_char=list('\~!@#.,[abcdefghij]wmnoxy$%;-=<>?:|^&*/ ')
def get_char(r,b,g,alpha=256):
if alpha==0:
return ' '
gray=int(0.2126*r+0.7125*g+0.0722*b)
uint=256/len(ascii_char)
return ascii_char[int(gray/uint)]
def run():
img=Image.open('0.jpg')
WIDTH,HEIGHT=100,60
img=img.resize((WIDTH,HEIGHT))
txt=""
for i in range(HEIGHT):
for j in range(WIDTH):
txt+=get_char(*img.getpixel((j,i)))
txt+='\n'
with open("pic.txt",'w') as fo:
fo.write(txt)
print(txt)
run()
