PIL库将图片转成字符

Posted 2022-03-10 liunlls

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('\\[email protected]#.,[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()
