1. 代码

python 复制代码

from PIL import Image


def process():
    print(f'Hello, World!')
    # 打开图片
    image = Image.open(r'logo.png').convert('L')  # 将图片转为灰度模式，这里需把'your_image_path.jpg'替换为你实际图片路径

    # 设置缩放比例，例如0.2表示将图片缩小为原来的20%，可按需调整
    scale = 0.2
    new_width = int(image.width * 0.1)
    new_height = int(image.height * 0.05)
    image = image.resize((new_width, new_height))

    width, height = image.size

    # 定义用于替换像素的字符集，从亮到暗
    ascii_chars = [' ', '.', '-', '=', '+', '*', '#', '%', '@']

    result = []
    for y in range(height):
        line = ""
        for x in range(width):
            pixel = image.getpixel((x, y))
            # 根据像素值映射到字符集
            char_index = int(pixel / 256 * len(ascii_chars))
            line += ascii_chars[char_index]
        result.append(line)

    # 将结果写入文件
    with open('banner.txt', 'w') as f:
        for line in result:
            f.write(line + '\n')


if __name__ == '__main__':
    process()
