python使用PIL模块生成验证码

import Image, ImageDraw, ImageFont, ImageFilter
import random

# 随机字母
def rndChar():
return chr(random.randint(65, 90))

# 随机颜色1
def rndColor():
return (random.randint(64, 255), random.randint(64, 255), random.randint(64, 255))

# 随机颜色2
def rndColor2():
return (random.randint(32, 127), random.randint(32, 127), random.randint(32, 127))

# 240 * 60
width = 60 * 4
height = 60
image = Image.new('RGB', (width, height), (255,255,255))

# 创建Font对象
font = ImageFont.truetype('/usr/share/fonts-droid/truetype/DroidSansFallback.ttf', 36)

# 创建Draw对象
draw = ImageDraw.Draw(image)

# 填充每个像素
for x in range(width):
for y in range(height):
draw.point((x, y),fill=rndColor())

# 输出文字
for t in range(4):
draw.text((60 * t +10, 10), rndChar(), font=font, fill=rndColor2())

# 模糊
image = image.filter(ImageFilter.BLUR)
image.save('/home/godben/code.jpg', 'jpeg')
