前言

本文提供给图片添加文字或者logo图片水印的python工具，打造专属图片。

环境依赖

ffmpeg环境安装，可以参考我的另一篇文章：windows ffmpeg安装部署_阿良的博客-CSDN博客

ffmpy安装：

pip install ffmpy -i https://pypi.douban.com/simple

代码说明

1、image_add_text方法给图片添加文字水印方法，主要参数为：图片路径、输出目录、

水印文字、字体名称、字体大小（默认100）、文字左上角坐标（默认0:0）、文字颜色（默认蓝色）、是否需要背景（默认需要为1，不需要为0）、背景色（默认白色）。

2、image_add_logo方法给图片添加logo，主要参数为：图片路径、输出目录、logo图片地址、文字左上角坐标（默认0:0）。

3、注意logo地址如果有类似C:/这种windows盘的路径情况，需要对":"进行转义。后面验证的时候，可以看看我给的参数。

4、文件名为了避免重复，采用了uuid作为文件名。

5、图片后缀格式校验只有两种，按需添加即可。

验证一下

准备的素材如下，分别为图片与logo图

验证代码

if __name__ == "__main__":    print(        image_add_text(            "C:/Users/huyi/Desktop/1.jpg",            "C:/Users/huyi/Desktop/", "剑客阿良_ALiang", "微软雅黑", box=0))    print(        image_add_logo(            "C:/Users/huyi/Desktop/1.jpg",            "C:/Users/huyi/Desktop/", "C//:/Users/huyi/Desktop/logo.png", (30, 10)))

 注意我给出的logo地址路径有什么不同。
