python练习七十：图片生成

题目：使用python生成类似于下图的字母验证码图片

实现代码:

from PIL import Image,ImageFont,ImageDraw,ImageFilter
import random

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

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

#随机颜色2
def randColor2():
    return (random.randint(32,127),random.randint(32,127),random.randint(32,127))

width,height = 240,60   #定义画布大小
image = Image.new("RGB",(width,height),(255,255,255))
#创建Font对象
font = ImageFont.truetype("C:\Windows\Fonts\ITCBLKAD.TTF",36)  #字体必须是ttf格式
draw = ImageDraw.Draw(image) #创建Draw对象

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

#生成文字
for t in range(4):
    draw.text((60*t + 10,10),randChar(),font=font,fill=randColor2())

image = image.filter(ImageFilter.BLUR)#模糊处理
image.save('text.jpg',"jpeg")
