最近在用Python开发自己的博客,需要用到Python生成验证码,当然肯定要用到Python的图形处理库PIL,因为我用的是windows。
所以在安装好pil之后就开始写,就按照题目所说出现了The _imagingft C module is not installed 错误,找了很多建议,最后确定在windows下应该用pillpw。下载地址点击打开链接找到Pillow?2.5.2.win32?py2.7.exe因为我用的是python2.7和win32系统,所以就应该下载这个,大家可以根据自己的需求找到响应的包进行安装,Pillow, 它是对PIL的一些BUG修正后的编译版
到了这里又遇见一个错误,那就是在使用Image.save(‘code.jpg‘,‘jpg‘)的时候会出现KeyError:’jpg‘错误,
看stackoverflow文章http://stackoverflow.com/questions/21128256/why-does-pillow-not-recognize-the-jpeg-format
受到启发之后只需要把import Image改为from PIL import Image 就行了
顺便附上一个生产中文验证码的代码
import ImageDraw,ImageFont from PIL import Image import random import math, string class RandomChar(): @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 << 8 ) | (body << 4) | tail str = "%x" % val return str.decode('hex').decode('gb2312') class ImageChar(): def __init__(self, fontColor = (0, 0, 0), size = (100, 40), fontPath = 'simsun.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,'jpeg') if __name__=='__main__': ic = ImageChar(fontColor=(100,211, 90)) ic.randChinese(4) ic.save("1.jpeg")
