字符画效果

1.代码：

from PIL import Image
ascii_char = list('"$%_&WM#*oahkbdpqwmZO0QLCJUYXzcvunxrjft/\|()1{}[]?-/+@<>i!;:,\^`.')
def get_char(r, b, g, alpha=256):
    if alpha == 0:
        return ' '
    gray = int(0.2126 * r + 0.7152 * g + 0.0722 * b)
    unit = 256 / len(ascii_char)
    return ascii_char[int(gray//unit)]
def main():
    im = Image.open('A.jpg')
    WIDTH, HEIGHT = 100, 60
    im = im.resize((WIDTH, HEIGHT))
    txt = ""
    for i in range(HEIGHT):
        for j in range(WIDTH):
            txt += get_char(*im.getpixel((j, i)))
        txt += '\n'
    fo = open("A.txt","w")
    fo.write(txt)
    fo.close()
main()
