如何从原始数据创建验证码镜像

from PIL import Image, ImageDraw, ImageFont
import random

def generate_captcha(text='ABCD', size=(120, 40), font_path='arial.ttf', font_size=30):
    # 创建图像
    image = Image.new('RGB', size, color=(255, 255, 255))
    draw = ImageDraw.Draw(image)
    
    # 设置字体
    font = ImageFont.truetype(font_path, font_size)
    
    # 绘制文本
    text_width, text_height = draw.textsize(text, font=font)
    x = (size[0] - text_width) / 2
    y = (size[1] - text_height) / 2
    draw.text((x, y), text, font=font, fill=(0, 0, 0))
    
    # 添加噪点
    for _ in range(100):
        draw.point((random.randint(0, size[0]), random.randint(0, size[1])), fill=(128, 128, 128))
    
    # 保存图像
    image.save('captcha.png')
    return image

# 生成验证码
captcha_image = generate_captcha()
captcha_image.show()
