用ASCII字符转化图片

代码

from PIL import Image# 定义 ASCII 字符集，从最暗到最亮
ASCII_CHARS = "@%#*+=-:. "def resize_image(image, new_width=100):width, height = image.sizeratio = height / widthnew_height = int(new_width * ratio)resized_image = image.resize((new_width, new_height))return resized_imagedef grayify(image):grayscale_image = image.convert("L")return grayscale_imagedef pixels_to_ascii(image):pixels = image.getdata()characters = "".join([ASCII_CHARS[pixel // 25] for pixel in pixels])return charactersdef main(new_width=100):image_path = input("请输入图片的路径: ")try:image = Image.open(image_path)except Exception as e:print(f"无法打开图片: {e}")returnnew_image_data = pixels_to_ascii(grayify(resize_image(image, new_width)))pixel_count = len(new_image_data)ascii_image = "\n".join([new_image_data[index:(index + new_width)] for index in range(0, pixel_count, new_width)])print(ascii_image)with open("ascii_image.txt", "w") as f:f.write(ascii_image)if __name__ == "__main__":main()
