Python 如何为模型创建.py文件

draw.py

from PIL import Image
import argparse

parser = argparse.ArgumentParser()

parser.add_argument('file')
parser.add_argument('-o', '--output')
parser.add_argument('--width', type = int, default = 80)
parser.add_argument('--height', type = int, default = 80)

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;:,\"^`'. ")

def get_char(r,b,g,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

    if OUTPUT:
        with open(OUTPUT,'w') as f:
            f.write(txt)
    else:
        with open("output.txt",'w') as f:
            f.write(txt)

使用上面代码中的

python draw.py image.png

我可以得到如下ascii图像：

现在我想让它成为一个模型，这样我就可以导入它，然后我用image.jpgor bmp，png…制作一个ascii图像。。。。在同一路径中，只需使用一个函数即可将其打印出来，并将其写入txt文件

from PIL import Image
import argparse

parser = argparse.ArgumentParser()

parser.add_argument('file')
parser.add_argument('-o', '--output')
parser.add_argument('--width', type = int, default = 80)
parser.add_argument('--height', type = int, default = 80)

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;:,\"^`'. ")

def get_char(r,b,g,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

    if OUTPUT:
        with open(OUTPUT,'w') as f:
            f.write(txt)
    else:
        with open("output.txt",'w') as f:
            f.write(txt)

txt=draw.get\u ascii\u imagemyPATH，表示未定义全局名称“宽度”

import draw

txt = draw.get_ascii_image("PATH", width=80, height=80)
draw.save(txt, "DESTINATION_PATH")
