Python如何将图片转换成字符

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()
