第 0010 題:使用 Python 生成類似於下圖中的字母驗證碼圖片
# -*- coding: utf-8 -*-
from PIL import Image, ImageDraw, ImageFont, ImageFilter
import random
# 隨機字母:
def rndChar():
return chr(random.randint(65, 90))
# 隨機顏色1:
def rndColor():
return (random.randint(64, 255), random.randint(64, 255), random.randint(64, 255))
# 隨機顏色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))
# 創建Font對象:
font = ImageFont.truetype('Arial.ttf', 36)
# 創建Draw對象:
draw = ImageDraw.Draw(image)
# 填充每個像素:
for x in range(width):
for y in range(height):
draw.point((x, y), fill=rndColor())
# 輸出文字:
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('code.jpg', 'jpeg')
