python代码
代码如下:
# -*- coding: utf-8 -*-
 import image,imagedraw,imagefont
 import random
 import math, string  
 class randomchar():
   用于随机生成汉字
   @staticmethod
   def unicode():
     val = random.randint(0x4e00, 0x9fbf)
     return unichr(val)  
   @staticmethod
   def gb2312():
     head = random.randint(0xb0, 0xcf)
     body = random.randint(0xa, 0xf)
     tail = random.randint(0, 0xf)
     val = ( head
     str = %x % val
     return str.decode('hex').decode('gb2312')
class imagechar():
   def __init__(self, fontcolor = (0, 0, 0),
                      size = (100, 40),
                      fontpath = 'wqy.ttc',
                      bgcolor = (255, 255, 255),
                      fontsize = 20):
     self.size = size
     self.fontpath = fontpath
     self.bgcolor = bgcolor
     self.fontsize = fontsize
     self.fontcolor = fontcolor
     self.font = imagefont.truetype(self.fontpath, self.fontsize)
     self.image = image.new('rgb', size, bgcolor)  
   def rotate(self):
     self.image.rotate(random.randint(0, 30), expand=0)  
   def drawtext(self, pos, txt, fill):
     draw = imagedraw.draw(self.image)
     draw.text(pos, txt, font=self.font, fill=fill)
     del draw  
   def randrgb(self):
     return (random.randint(0, 255),
            random.randint(0, 255),
            random.randint(0, 255))  
   def randpoint(self):
     (width, height) = self.size
     return (random.randint(0, width), random.randint(0, height))  
   def randline(self, num):
     draw = imagedraw.draw(self.image)
     for i in range(0, num):
       draw.line([self.randpoint(), self.randpoint()], self.randrgb())
     del draw
def randchinese(self, num):
     gap = 5
     start = 0
     for i in range(0, num):
       char = randomchar().gb2312()
       x = start + self.fontsize * i + random.randint(0, gap) + gap * i
       self.drawtext((x, random.randint(-5, 5)), randomchar().gb2312(), self.randrgb())
       self.rotate()
     self.randline(18)  
   def save(self, path):
     self.image.save(path)
调用方法
代码如下:
ic = imagechar(fontcolor=(100,211, 90))
 ic.randchinese(4)
 ic.save(1.jpeg)
