beauty's Introduction

一键美肤功能--beauty

首先 (￣▽￣)* 我们来分析下功能--拆解步骤就是

  1. 复制图层

  2. 图层模式滤色

  3. 高斯模糊

  4. 透明度降至75%

  5. 调整图片饱和度

关于这里的公式可以搜Photoshop图层混合模式计算公式大全 里面可以查到各种算法

(づ￣ 3￣)づ最后是关于饱和度的实现啦

  • 首先要把rgb转为hsv --->o(╯□╰)o 因为人家只搜到rgb转hsv的转换方法啦

  • 然后捏调整饱和度我调了一米米 大家可以根据需要来改数值

  • 最后再转为rgb就好了喵~o( =∩ω∩= )m
