这篇教程Python 实现给图片加文字或logo水印写得很实用，希望能帮到您。
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，ffmpy安装： pip install ffmpy -i https://pypi.douban.com/simple
代码上代码。 #!/user/bin/env python# coding=utf-8"""@project : csdn@author : 剑客阿良_ALiang@file : image_add_watermark_tool.py@ide : PyCharm@time : 2021-11-20 14:18:13"""import osimport uuidfrom ffmpy import FFmpeg # 图片加文字水印def image_add_text( image_path: str, output_dir: str, text: str, font_name: str, font_size=100, position=(0, 0), font_color='blue', box=1, box_color='white'): ext = _check_format(image_path) result = os.path.join(output_dir, '{}.{}'.format(uuid.uuid4(), ext)) ff = FFmpeg( inputs={ image_path: None}, outputs={ result: '-vf drawtext=/"fontsize={}:fontfile={}:text=/'{}/':x={}:y={}:fontcolor={}:box={}:boxcolor={}/"'.format( font_size, font_name, text, position[0], position[1], font_color, box, box_color)}) print(ff.cmd) ff.run() return result # 图片添加logodef image_add_logo( image_path: str, output_dir: str, logo_path: str, position=(0, 0)): ext = _check_format(image_path) result = os.path.join(output_dir, '{}.{}'.format(uuid.uuid4(), ext)) filter_cmd = '-vf /"movie=/'{}/' [wm];[in] [wm]overlay={}:{} [out]/"' ff = FFmpeg( inputs={ image_path: None}, outputs={ result: filter_cmd.format(logo_path, position[0], position[1])}) print(ff.cmd) ff.run() return result def _check_format(image_path: str): ext = os.path.basename(image_path).strip().split('.')[-1] if ext not in ['png', 'jpg']: raise Exception('format error') return ext 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。
