将jpg图片解码为文字

from PIL import Image

def decode(image):
    #得到图片的大小
    width, height = image.size
    ls = []
    for i in range(height):
        for j in range(width):
            #获得每个位置上的rgb值
            r, g, b = image.getpixel((j, i))
            #获得每个像素对应的汉字字符
            word_number = (r << 16) + (g << 8) + b
            word_string = chr(word_number)
            ls.append(word_string)
    #将列表合成为字符创
    text_result = "".join(ls)
    return text_result

def main():
    #打开图片
    image = Image.open("C:/users/mike1/desktop/PictureForText.png", "r")
    text = decode(image)
    with open("C:/users/mike1/desktop/PictureToText.txt", "w", encoding = "utf-8") as f:
        f.write(text)

if __name__ == "__main__":
    main()



    

 

与原文本一模一样，文件大小为1.74M，比原图片大。
