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
上代码。

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。
