#图片大小240*60：
width = 60 * 4
height = 60
image = Image.new('RGB', (width, height), (155, 155, 155))

#创建Font对象：
font = ImageFont.truetype('C:\Windows\Fonts\Arial.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=rndColor1())

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

#模糊处理：
image = image.filter(ImageFilter.BLUR)
image.save('test.jpg', 'jpeg')
print('生成成功！')
