字体输出成字符(pil应用)

就是将一些各种字体渲染过的字符，用单独的字母显示，不知咋说。
今天突然想起，咋以前没想到呢。
下面的示例用pil， 字体用的是隶书。windows下环境。
输出到1个文件，想得出清晰点的就靠改变fontsize了；
下面有空看看如何折腾图像

import Image,ImageFont
import random

def char2txt(inputchar,outfile='char2txt.out',fontsize=30,truetypefile='STLITI.TTF',
randstr='#$%*'):
    font = ImageFont.truetype(truetypefile,fontsize)    
    w, h = font.getsize(inputchar)
    im = Image.new('RGBA',(w,h))
    draw = ImageDraw.Draw(im)
    draw.text((0,0),inputchar.decode('gb2312'),font=font,fill='rgb(110,0,255)')
    imgdata = list(im.getdata())
    outfh=open(outfile,'wb')
    
    for i in range(len(imgdata)):
        if imgdata[i] == (0,0,0,0): outfh.write(' ')
        else:  outfh.write(random.choice(randstr))
        if ((i+1) % w) == 0:  outfh.write('\n')
   
    outfh.close()
   
char2txt('清明')
