最近在用Python開發自己的博客,需要用到Python生成驗證碼,當然肯定要用到Python的圖形處理庫PIL,因為我用的是windows。
所以在安裝好pil之后就開始寫,就按照題目所說出現了The _imagingft C module is not installed 錯誤,找了很多建議,最后確定在windows下應該用pillpw。下載地址 點擊打開鏈接 找到 Pillow‑2.5.2.win32‑py2.7.exe因為我用的是python2.7和win32系統,所以就應該下載這個,大家可以根據自己的需求找到響應的包進行安裝, Pillow, 它是對PIL的一些BUG修正后的編譯版
到了這里又遇見一個錯誤,那就是在使用Image.save('code.jpg','jpg')的時候會出現KeyError:’jpg‘錯誤,
看stackoverflow文章 http://stackoverflow.com/questions/21128256/why-does-pillow-not-recognize-the-jpeg-format
受到啟發之后只需要把import Image改為 from PIL import Image 就行了
順便附上一個生產中文驗證碼的代碼
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")
