Hello，1024背后可爱的人儿

# 用PIL包：

from PIL import Image

# 用于打印字符画的字符集：
ascii_char = list("$@B%8&WM#*oahkbdpqwmZO0QLCJUYXzcvunxrjft/\|()1{}[]?-_+~<>i!lI;:,\"^`'. ")

# 将像素值转换为对应的字符：
def rgb_to_char(r, g, b, 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)]

# 生成字符画
