把图片转换成字符画的小程序，效果如下
from PIL import Image
color = 'MNHQ$OC?7>!:-;.' #zifu
def to_html(func):
html_head = '''
<html>
<head>
<style type="text/css">
body {font-family:Monospace; font-size:5px;}
</style>
</head>
<body> '''
html_tail = '</body></html>'
# ding yi HTML
def wrapper(img):
pic_str = func(img)
pic_str = ''.join(l + ' <br/>' for l in pic_str.splitlines())
return html_head + pic_str + html_tail
return wrapper
# fan hui zhi
@to_html
def make_char_img(img):
pix = img.load()
pic_str = ''
width, height = img.size
for h in range(height):
for w in range(width):
pic_str += color[int(pix[w, h] * 14 / 255)]
pic_str += '\n'
return pic_str
def preprocess(img_name):
img = Image.open(img_name)
w, h = img.size
m = max(img.size)
delta = m / 200.0
w, h = int(w / delta), int(h / delta)
img = img.resize((w, h))
img = img.convert('L')
return img
def save_to_file(filename, pic_str):
outfile = open(filename, 'w')
outfile.write(pic_str)
outfile.close()
def main():
img = preprocess(input('input your filename:'))
pic_str = make_char_img(img)
save_to_file('char.html', pic_str)
if __name__ == '__main__':
main()
