Python（三） PIL, Image生成验证图片

 

安装好PIL，开始使用。

在PyCharm中新建一个文件：PIL_Test1.py

 

#  PIL 应用练习
#
# import PIL
# from PIL import Image
# a = Image.open("E:\\照片\\2017-8-6_北海公园\\QQ图片20170806213744.jpg")
# a.rotate(30).show()

from PIL 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 x 60:
width = 60 * 4
height = 60
image = Image.new('RGB', (width, height), (255, 255, 255))
# 创建Font对象:
font = ImageFont.truetype('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=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.show()
image.save('code.jpg', 'jpeg')

运行结果：

 

插曲：

中间出现编译错误：

Traceback (most recent call last):
File "E:/python_pycharm/PIL_Test1.py", line 35, in <module>
font = ImageFont.truetype('Arial.ttf', 36)
File "E:\python_pycharm\venv\lib\site-packages\PIL\ImageFont.py", line 280, in truetype
return FreeTypeFont(font, size, index, encoding, layout_engine)
File "E:\python_pycharm\venv\lib\site-packages\PIL\ImageFont.py", line 145, in __init__
layout_engine=layout_engine)
OSError: cannot open resource

改为font = ImageFont.truetype('arial.ttf', 36)即可
