Python特效之文字成像方法详解

作者:autofelix

文字成像,即将原图片经过 python 处理后,生成完全由纯文字组成的图像。本文将具体为大家介绍如何通过Python实现这一效果,感兴趣的可以学习一下

一、特效预览

处理前

处理后

细节放大后

二、程序原理

1.输入你想隐藏的文字

2.然后写到另一张跟照片同等大小的空白纸张上

3.将相同位置的文字的颜色用照片上相同位置的颜色填充即可

4.然后生成新的图片你听懂了吗 

三、程序源码

#!/usr/bin/env python
# encoding: utf-8
 
from PIL import Image, ImageDraw, ImageFont
 
class wordPicture:
    '''
     This is a main Class, the file contains all documents.
     One document contains paragraphs that have several sentences
     It loads the original file and converts the original file to new content
     Then the new content will be saved by this class
    '''
    def __init__(self):
        self.font_size = 7
        self.picture = 'assets/picture.jpeg'
 
    def hello(self):
        '''
        This is a welcome speech
        :return: self
        '''
        print('*' * 50)
        print(' ' * 20 + '文字成像')
        print(' ' * 5 + 'Author: autofelix  Date: 2022-01-06 13:14')
        print('*' * 50)
        return self
 
    def run(self):
        '''
        The program entry
        '''
        word = input('请输入你想说的:') or '我钟意你'
 
        resource = Image.open(self.picture)
        img_array = resource.load()
 
        image_new = Image.new('RGB', resource.size, (0, 0, 0))
        draw = ImageDraw.Draw(image_new)
        font = ImageFont.truetype('/System/Library/Fonts/PingFang.ttc', self.font_size)
 
        yield_word = self.character_generator(word)
 
        for y in range(0, resource.size[1], self.font_size):
            for x in range(0, resource.size[0], self.font_size):
                draw.text((x, y), next(yield_word), font=font, fill=img_array[x, y], direction=None)
 
        image_new.convert('RGB').save('result.jpeg')
 
    def character_generator(self, text):
        while True:
            for i in range(len(text)):
                yield text[i]
 
 
if __name__ == '__main__':
    wordPicture().hello().run()
