python 图片转字符画

Posted 2020-11-14 littlebob

整代码:

将以下代码保存为py文件

from PIL import Image
import argparse

#命令行输入参数处理
parser = argparse.ArgumentParser()

parser.add_argument(\'file\')     #输入文件
parser.add_argument(\'-o\', \'--output\')   #输出文件
parser.add_argument(\'--width\', type = int, default = 80) #输出字符画宽
parser.add_argument(\'--height\', type = int, default = 80) #输出字符画高

#获取参数
args = parser.parse_args()

IMG = args.file
WIDTH = args.width
HEIGHT = args.height
OUTPUT = args.output

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

# 将256灰度映射到70个字符上
def get_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)]

if __name__ == \'__main__\':

    im = Image.open(IMG)
    im = im.resize((WIDTH,HEIGHT), Image.NEAREST)

    txt = ""

    for i in range(HEIGHT):
        for j in range(WIDTH):
            txt += get_char(*im.getpixel((j,i)))
        txt += \'\\n\'

    print(txt)

    #字符画输出到文件
    if OUTPUT:
        with open(OUTPUT,\'w\') as f:
            f.write(txt)
    else:
        with open("output.txt",\'w\') as f:
            f.write(txt)

把要转成字符画的图片置于该文件的同级目录下

 

然后cmd打开命令行窗口
