将字符串转换为图像，并保存字符串的txt文件，如image

from PIL import Image, ImageDraw, ImageFont

def convert_string_to_image(string, image_path, text_path):
    # 设置图像尺寸和背景颜色
    width = 400
    height = 200
    background_color = (255, 255, 255)

    # 创建图像对象
    image = Image.new('RGB', (width, height), background_color)
    draw = ImageDraw.Draw(image)

    # 设置字体和字体大小
    font_size = 30
    font = ImageFont.truetype('arial.ttf', font_size)

    # 计算文本的宽度和高度
    text_width, text_height = draw.textsize(string, font=font)

    # 计算文本在图像中的位置
    x = (width - text_width) // 2
    y = (height - text_height) // 2

    # 在图像上绘制文本
    draw.text((x, y), string, fill=(0, 0, 0), font=font)

    # 保存图像文件
    image.save(image_path)

    # 保存字符串到txt文件
    with open(text_path, 'w') as file:
        file.write(string)

# 示例调用
string = "Hello, World!"
image_path = "image.png"
text_path = "text.txt"
convert_string_to_image(string, image_path, text_path)
