 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

ic = ImageChar(fontColor=(100,211, 90)) 

ic.randChinese(4) 
ic.save("1.jpeg")
